How often have your new year's resolutions failed? For a majority of individuals, the answer is most if not all. Often the problem has to do with the type of resolution you set and whether it is truly achievable. Unfortunately, many set unrealistic goals and once they "fall off the wagon" feel they failed. This article discusses the most common resolutions and how to go about setting yourself up for success.
Every January 1, millions of people make New Year's resolutions. Chances are, they won't stick around for too long. Why?
Because most resolutions are unrealistic, or even unreasonable. Here are seven outdated fitness and nutrition resolutions that are destined — and deserve — to fail, along with smarter options to make sure you follow through and succeed.
This is an amusing Ted talk about positive psychology, a focus on resilience and strength. Dr. Shawn Achor shares insights into how we can become more positive and in turn become more productive and creative. There are simple steps you can take to reprogram your mind into a more positive frame of being and acting.
From Ted website: We believe that we should work to be happy, but could that be backwards? In this fast-moving and entertaining talk, psychologist Shawn Achor argues that actually happiness inspires productivity. (Filmed at TEDxBloomington.)
Ever wonder what happens in the brain when you are curious? Why does being curious help you learn? In a new study on curiosity, these questions are answered.
The brain is magnificent. Sleep and its function is one more reason to marvel at it's efficiency. Watch this informative and entertaining Ted talk on how the brain "cleans up" during sleep.
From Ted.com website: The brain uses a quarter of the body's entire energy supply, yet only accounts for about two percent of the body's mass. So how does this unique organ receive and, perhaps more importantly, rid itself of vital nutrients? New research suggests it has to do with sleep.
We hear about how bad stress is for our health, but just how bad is it? This article sheds some important light on this issue. It is more important than ever to address your chronic stress through exercise, self care activities, social support and even therapy.
Elissa Epel is studying how personality, stress processes and environment affect our DNA — and how we might lessen damaging effects.
What do you do when your child is disappointed? How do you manage those moments so they become a learning opportunity. In this article I was interviewed on how to help your children learn and grow when they don't succeed.
No one – including Supermom – can prevent kids from experiencing setbacks in life. Your daughter may miss the class field trip because she caught a nasty cold. Or she may come home crying when her science-fair project earns a less-than-hoped-for grade. Kids’ disappointments are no fun for parents to witness. But kids learn to lift themselves up when they get knocked down. Marriage and family therapist Christina Steinorth, M.A., author of “Cue Cards for Life” (Hunter House, 2013), says parents can help kids learn to bounce back from adversities by taking a teaching role. During tough times, aim to build your child’s coping skills and reinforce the value of persistence. Here’s how.
Food is comfort. It is no surprise that when we are upset we turn to food to soothe ourselves. Turns out that there is growing research supporting the idea that different foods can help you feel less stressed. Read below for more information.
Can erotic romances be good for you? There are multiple reasons why these books can help you improve your love life beyond providing entertainment.
By Charlotte Rose
Although erotic romance books have been around for a long time, they have experienced an amazing resurgence since Fifty Shades of Grey. And they have gone mainstream!
When I wrote my first erotic romance 20 years ago, it was sold in the secret back section of book stores or sex novelty shops, or by mail order, in a plain brown wrapper. How things have changed! Books are so much more accessible now due the advent of the e-reader, the convenience (and addictive nature) of technological wonders such as the Amazon “one click” buying method, and the explosion in self-published books in the erotic romance genre.
Can music help improve your physical and mental health? Listen to this 10 minute lecture of music and its healing effects.
Can music make us healthier or even smarter? Can it change how we experience pain? In this episode, former rock musician and studio producer Daniel Levitin, PhD, talks about how music changes our brain’s chemistry and affects our health.
Nannies are more than babysitters. They nurture while mommies are away. I was recently quoted in an article discussing how nannies can create a warm and trusting relationship with the children they are responsible for. For moms, making sure your nanny is connecting with your child is essential, these are techniques you can share with your nanny to help foster the kind of bonded and safe relationship you want for your children.
There is nothing more precious than a child who wraps his or her arms around your neck and enjoys the comfort and nurturing you provide. As a nanny, a mom/child relationship is only natural when you have bonded with a little one.
It takes time, creativity and a sense of trust to establish this close relationship with the children you care for on a daily basis. In order to enhance the nurturing environment and a child’s sense of comfort in your care, begin by creating a bond that will last a lifetime with loving actions and fun activities.
Why is parenting so difficult? What does it even mean to be a parent? This Ted talk frames these questions and puts present day parenting into context.
Ever wonder why the terrible 2s are so terrible? This article goes into 5 reasons why toddlers are different and why it is important to nurture those differences.
by Rebecca M Gruber
Sometimes parenting books feel like they're a dime a dozen — a handful cross my desk each week promising to provide the definitive method for raising sweet, well-adjusted tots — spoiler alert: few actually do. But when I learned that Dr. Tovah Klein, a mother of three and the director of the Barnard College Center For Toddler Development in NYC who has been observing toddlers for over 20 years, would be speaking at my son's preschool PTA meeting, I made sure I was seated in the front row to hear her philosophy and learnings firsthand. Dr. Klein's recently released How Toddlers Thrive: What Parents Can Do Today For Children Ages 2-5 to Plant the Seeds of Lifelong Success ($19, originally $25) was already generating buzz, and after hearing her in person, I understand why.
Based on the philosophy that toddlers are not miniadults, that they're individuals fueled by a desire to know was just the beginning. In just 45 minutes Dr. Klein took us deep into the magical world of the toddler years and got to the root of many of our biggest frustrations with our tots. I learned a few fascinating philosophies about young kids that have already helped me better understand my child. I highly suggest you pick up a copy, but in the interim, here are a handful of teasers you'll find in the book.
1: Toddlers Have No Sense of Time
2: To Them, the World Is All About Power and Control
3: Happiness Doesn't Come From Trying to Make Them Happy
4: They Need to Stumble and Fall
5: The Qualities That Drive Us Nuts Now Are the Ones We'll Want Later

The new year seems to trigger discussions about connections, loneliness and friendships. Perhaps a time for reflection or a reaction to all the expectations of gathering with others around the holidays. This article explores and explains the importance of social connections to our emotional and physical health.
New research by psychologists uncovers the health risks of loneliness and the benefits of strong social connections.

It took a trip to the hospital for Cathryn Jakobson Ramin, 56, to confront a nagging concern she'd had for years: She had no friends. "I didn't have one person who could pick me up," says the journalist in Mill Valley, Calif., who went to the hospital for a small medical procedure.
Ramin does have many friends — those she first met in childhood and in the four cities she's lived in as an adult — but they don't live nearby anymore. She also has a strong marriage, two grown sons and a successful career. But she has few local friends she can call on in a time of need — or for simple companionship.
"I like the sense of sitting in someone's kitchen with a cup of tea and cookies and just shooting the [breeze]," she says, admitting she feels a void. "That to me is a very important part of life."
Psychologists agree. While research on relationships has skirted adult friendships — tending to focus on adolescent friendships and adult romances — the importance of strong social connections throughout life is gaining scientific clout, having been linked with such benefits as a greater pain tolerance, a stronger immune system, and a lower risk of depression and early death.
"For years and years … people speculated that if you felt alone or you lived alone or you were alone a lot, you wouldn't eat good meals, you wouldn't exercise as much, nobody would take you to the doctor," says Laura Carstensen, PhD, who directs Stanford University's Center on Longevity. "But I think what we're learning is that emotions cause physiological processes to activate that are directly bad for your health."
Yet forging platonic relationships isn't always easy. Ramin's situation appears to be increasingly common: According to a meta-analysis with more than 177,000 participants, people's personal and friendship networks have shrunk over the last 35 years (Psychological Bulletin, 2013).
Combine that trend with the United States's rising age of first marriage, a divorce rate nearing 50 percent and a life expectancy that's at an all-time high, and you get "a demographic shift such that there are now [more] people who don't have a marital partner to supply the intimacy they need," says Beverley Fehr, PhD, a social psychologist at the University of Winnipeg and author of the 1996 book "Friendship Processes." "In light of those shifts, I think that friendships are more important today than ever before."
I'm so lonesome I could die
A lack of friends isn't simply an inconvenience when you want a movie partner or a ride to the hospital. A sparse social circle is a significant health risk, research suggests. In one meta-analysis of 148 studies comprising more than 308,000 people, for example, Brigham Young University psychologists found that participants with stronger social relationships were 50 percent more likely to survive over the studies' given periods than those with weaker connections — a risk comparable to smoking up to 15 cigarettes a day and one double that of obesity. And the risks of poor relationships are likely greater, the researchers say, since the studies didn't look at the quality of participants' social connections (PLOS Medicine, 2010).
There's some evidence that more really is merrier. In one recent study tracking 6,500 British men and women ages 52 and older, psychologist Andrew Steptoe, PhD, of the University College London and colleagues found that both feeling lonely and being socially isolated raised the risk of death. However, only social isolation — measured in terms of frequency of contact with family and friends, and participation in organizations outside of work — appeared to be related to increased mortality when the researchers adjusted for demographic factors and baseline health (PNAS, 2013).
But contrary to Steptoe's findings, most research indicates that feeling isolated is more dangerous than being isolated, says psychologist John Cacioppo, PhD, co-author of the 2008 book "Loneliness: Human Nature and the Need for Social Connection." In one 2012 study, he and colleagues looked at data from more than 2,100 adults ages 50 and older and found that feelings of loneliness were associated with increased mortality over a six-year period. The finding was unrelated to marital status and number of relatives and friends nearby, as well as to health behaviors such as smoking and exercise (Social Science and Medicine, 2012).
"It's not being alone or not" that affects your health, Cacioppo says. "You can feel terribly isolated when you're around other people."
In his ongoing Chicago Health Aging and Social Relations Study, funded by the National Institute on Aging, Cacioppo and colleagues have also linked loneliness with depressive symptoms and an increase in blood pressure over time.
Other research indicates positive social connections might accelerate disease recovery. In a study of 200 breast cancer survivors, psychologist Lisa Jaremka, PhD, and colleagues at the Ohio State University found that lonelier women experienced more pain, depression and fatigue than those who had stronger connections to friends and family. The more disconnected women also had elevated levels of a particular antibody associated with the herpes virus — a sign of a weakened immune system (Psychoneuroendocrinology, 2013).
Particular genes may play a role in explaining why our bodies are so attuned to our social lives, says psychologist Steve Cole, PhD, at the University of California, Los Angeles. In one study, he and colleagues including Cacioppo analyzed the gene expression profiles of chronically lonely people and found that genes expressed within two subtypes of white blood cells are uniquely responsive to feelings of loneliness. The cells — plasmacytoid dendritic cells and monocytes — are associated with diseases such as atherosclerosis and cancer, as well as "first line of defense" immune responses (PNAS, 2011).
Cole says the most "biologically toxic" aspect of loneliness is that it can make you feel chronically threatened, an emotion that can wear on the immune system. "It's really that sense of unsafe threat, that vague worry, that's probably what's actually kicking off the fight-or-flight stress responses that affect the immune system most directly," he says.
Friends in adulthood
As researchers work to better understand the link between friendships and health, they're also helping to answer a question familiar to anyone who's ever moved to a new city, lost a spouse or otherwise found themselves feeling alone: How do you make friends as an adult? Here's what the research suggests might work:
Be a familiar face. The idea that familiarity breeds attraction is long-established by research, and was again supported in a 2011 study led by psychologist Harry Reis, PhD, at the University of Rochester. In the first experiment, same-sex strangers rated how much they liked one another after having several structured conversations. In the other, strangers chatted freely online. In both cases, the amount participants liked their partners increased with each exchange (Journal of Personality and Social Psychology, 2011).
Rachel Bertsche, a writer in Chicago, witnessed this phenomenon outside of the lab when she joined a weekly comedy class a few years ago. At first, she thought her classmates were strange. But she gradually changed her mind — and soon wound up joining the group for drinks after class. "Consistency is so important," she says.
Fehr agrees. She says sticking to a simple routine — whether it's going to the same coffee shop at the same time every day, joining a class like Bertsche or even just going to the office mailroom when it's most crowded — can help turn strangers into friends.
Divulge a secret. There are ways to make fast friends, too, psychologists say. Research by Stony Brook University professor Arthur Aron, PhD, showed that gradually increasing the depth of questions and answers between strangers can spawn friendships in just 45 minutes (Personality and Social Psychology Bulletin, 1997). Fehr and her team are building on this model by directing a couple of college buddies first to ask each other neutral questions, such as, "When did you last go to the zoo?" and slowly build up to more intimate questions such as, "If you knew someone close to you was going to die tomorrow, what would you tell them today — and why haven't you told them yet?"
So far, she's seeing men's friendships getting stronger. "When they do open up to each other, they feel closer to each other and they feel more satisfaction with the relationship," she says.
Realize it's in your head. Loneliness is a subjective experience that can often be a self-fulfilling prophecy, says Cacioppo. "When people feel isolated, the brain goes into self-preservation mode," he says, meaning that they become preoccupied with their own — not others' — welfare. While the response is an innate one meant to protect us from threats, over time, it harms physical and mental health and well-being, and makes us more likely to see everything in a negative light. It can also make us seem cold, unfriendly and socially awkward. But recognizing what's in your head can help you get out of it, Cacioppo says.
In a review of interventions to reduce loneliness, he and colleagues found that those that encouraged participants to challenge their own negative thought processes — for example, by sharing a positive part of their day with someone else — were more effective than interventions seeking to improve social skills, enhance social support or increase opportunities for social contact. "It has a surprising effect," Cacioppo says. (Personality and Social Psychology Review, 2010).
Log on, with caution. Liz Scherer, a copywriter in Silver Spring, Md., used social media to forge friendships when she moved from New York City to Annapolis, Md., about 10 years ago at age 42. Through Twitter, she connected online with others in her business and met many of them in person at social media conferences. "I've made some really good friends who I talk to … every single day," she says. "They're good social supports and business supports."
Research suggests Scherer's positive experience with social media is most common among people who are already well connected. A review of four studies by psychologist Kennon Sheldon, PhD, of the University of Missouri, and colleagues, for example, found that more time on Facebook was linked to both high and low levels of connectedness. Psychologists posit this may be the case because Facebook supports relationships among those who are already highly socially connected, but might make those who are isolated feel even more so (Journal of Personality and Social Psychology, 2011).
"If you rely on virtual relationships entirely, that's probably bad for you," Carstensen says. "But when you're using email and face time to supplement real relationships, that's a good thing."
Don't force it. If the pressure to forge new relationships is more external than internal, put away the "friend wanted" ad and focus on what and who does make you happy, says Carstensen. "If people are not very socially active and they aren't necessarily interested in expanding their social networks, and they seem OK emotionally, then you shouldn't feel alarmed," she says.
After all, being highly connected has its downsides, too, says University of Sheffield psychologist Peter Totterdell, PhD, who studies social networks in organizations. He's found that people with large work-based networks tend to be more anxious than those with fewer connections. "Possibly what's going on there is that you get more possibilities, more resources, but at the same time you've got more responsibility as well," he says.
And trying to change who you are can backfire, since people's likelihood to forge connections seems to be relatively constant throughout life, Totterdell says. "People may have a natural inclination, and to try to change that [may] make them uncomfortable with the results," he says.
The bottom line? Whether you're content with two close friends or prefer to surround yourself with 20 loose acquaintances, what matters is that you feel a part of something greater than yourself, Carstensen says.
"We shouldn't judge people who say, ‘I'm not a party goer, I don't want to make friends, I don't want to hang out in the bars or the clubs' — that's fine," she says. "There's a whole bunch of people who feel the same way."
This is a great article about a counter intuitive phenomenon. How can you want to fall asleep when you are clearly upset. Mr. Wolfson explores the possible psychological and biological explanations in this article.
Last month, my wife and I found ourselves in a disagreement about whether or not our apartment was clean enough for guests—the type of medium-sized disagreement that likely plagues all close relationships. In the midst of it, there was a lull and, feeling exhausted all of a sudden, I got up and left the living room. In the bedroom, I immediately fell face down into the sheets. The next thing I knew it was 20 minutes later and my wife was shaking me awake. I hadn’t meant to fall asleep; I just felt so fatigued in that moment that there was nothing else I could do.
This wasn’t new for me. A few weeks earlier, I had come into conflict with an acquaintance over some money. We were exchanging tense emails while I was at my office, and I began to feel the slow oozing onset of sleep, the same tiredness that came on when, as a child, I rode in the backseat of the car on the way home from some undesired trip. A sleepiness that overtakes the body slowly but surely and feels entirely outside of your control.
Though this has happened many times before, my response to conflict still seems strange to me. After all, as everyone knows from 9th grade biology class, when faced with stress—an acute threat—our bodies enter fight-or-flight mode. It’s supposed to be automatic: the adrenal cortex releases stress hormones to put the body on alert; the heart begins to beat more rapidly; breathing increases frequency; your metabolism starts to speed up, and oxygen-rich blood gets pumped directly to the larger muscles in the body. The point is to become energized, to prepare to face the source of the conflict head on, or, at the worst, be ready to run away, at top speed.
Of course, you don’t actually want the stress response system to be too reactive. If you were constantly in fight or flight mode, constantly stressed, it could actually have long-term effects on your neurochemistry, leading to chronic anxiety, depression, and, well, more sleeplessness. Even so, it seems like a good idea to sometimes be on high alert when dealing with stressful situations.
But that’s not what my body did. My body shut down.
I asked around, and found out that many others experience the same thing. For example, Dawn, a family counselor in Columbus, Ohio, told me that her husband Brad often “starts yawning in the middle of heated discussions, and will even lie down and go right to sleep.” One time their toddler son fell down the stairs (he was fine), and Brad left the room and went to bed. Brad has had this kind of stress response for all 24 years of their relationship; Dawn says she’s used to it by now.
Even though dozens of people told me similar stories, I began to wonder what was wrong with us—what was wrong with me. Why was my body, in the face of conflict, simply acquiescing? Where was the fight in me?
There’s a concept in psychology called “learned helplessness” used to explain certain aspects of depression and anxiety. It’s fairly old, having been firstrecognized and codified in the 1970s, but has remained largely relevant and accepted within the field. The name (mostly) explains it all: If, at a very early stage in development, a living thing comes to understand that it is helpless in the face of the world’s forces, it will continue to perceive a lack of control, and therefore actually become helpless, no matter if the context changes.
In the early studies, dogs were divided into two groups: The first half were subjected to electric shocks, but were given a way to stop the shocks (they just had to figure it out themselves). The second group of dogs received shocks but had no way to avoid, escape, or stop them. The experience, sadly, had long-term effects on the animals. When faced with stressful environments later on in life, the first group of dogs did whatever they could to try to deal with it; the second group simply gave up. They had been conditioned to respond to stress with acquiescence.
This type of learned helplessness isn’t limited to animals; many of the adults I spoke with all mentioned childhood anxiety stemming from uncontrollable situations.
“When I hit high school and stress levels became higher in my life (messy divorce between my parents and lots of moving), I began escaping into sleep,” says LeAnna, a 25-year-old from Washington state. “As an adult, I still have ‘go to sleep’ impulses whenever I feel overwhelmed.” Daniel, from Baltimore told me that “whenever there was any kind of ‘family strife’ I would just go to my room and sleep.” Daniel is now 51, and starts yawning any time he encounters a stressful situation.
My parents divorced by the time I hit high school, but before they did, they fought a lot, usually in the kitchen beneath my bedroom. What I remember feeling most was powerlessness—not anger or sadness, but a shrug-your-shoulders, close-the-door, shut-your-eyes type of response because what was I going to do? Tell them to break it up?
That coping mechanism worked for me back then. I was able to compartmentalize those stressful experiences and move on with my life. I stayed in school and kept my grades up; I had friends and was relatively well-rounded. Things went well. But now, at 28, I still deal with interpersonal conflict by shutting the door and going to sleep. I act on feelings that are no longer relevant to the situation.
“Our feelings are always in the past,” says John Sharp, a psychiatrist at Harvard Medical School. “This is something that’s really outlived its adaptive value.” As an adult I should have control over my current situation, but I don’t. Am I like those lab dogs, shocked into helplessness?
At first glance, sleep might seem like quintessential avoidance, like burying your head in the pillow is no better than burying your head in the sand.
But I don’t feel as though I am not helping myself. After all, going to sleep isn’t like turning the lights off; the truth is that there’s a lot still going on while your eyes are closed. While we might be able to temporarily stave the flow of conflict by falling asleep, we’re not really escaping anything. In fact, sleep in some ways forces us to not only relive the emotional experience but to process and concretize it—by going to sleep I may be making the fight with my wife more real.
If you’re like me, you probably imagine memories work pretty simply: you have an experience, it gets stored somewhere, and then you retrieve it when you need it. But that leaves out a key step, memory consolidation, and that’s where sleep comes into play.
Here’s how it really works, according to Dr. Edward Pace-Schott, professor at Harvard Medical School’s Division of Sleep Medicine: When an experience is initially encoded as a memory, it rests in the brain’s short term storage facilities, where it is fragile, easily forgotten if other experiences come along quickly. In order for the experience to last, it needs to go through a process of consolidation, where it becomes integrated into other memories that you have. That’s why when you think of, say the 1993 baseball game between the Yankees and Orioles, you also think of bright green grass, the smell of peanuts and beer, your dad, and Bobby Bonilla, and not thousands of random bits and pieces.
Of course, not every experience is worth remembering. Only the highly intense experiences—positive or negative—are prioritized for storage later on. “Emotions put a stamp on a memory to say ‘this is important,’” says Pace-Schott. It makes sense: the color of the grocery store clerk’s shirt is significantly less essential than, say, your mother’s birthday.
If we didn’t shelve our memories appropriately, everything would be a jumble, and without consolidation, we would forget it all. Life would have no meaning, and more importantly (at least from an evolutionary standpoint) we would never learn anything—we’d be helplessly amorphous, easy prey.
Here’s the conundrum, though: the same experiences that are stamped as emotionally important can overwhelm your brain’s short term storage facilities. Dr. Rebecca Spencer, a professor at the University of Massachusetts Department of Psychology, likens it to a desk where “whatever is stressing you out is this big pile of papers, but there are also other memories piling up on you.” With more and more papers landing in front of you all day, you’ll never effectively get to them all. And emotionally rich experiences are all high priority messages, screaming to be dealt with right away. So what happens next?
“You can be driven to sleep simply by having a lot of emotional memories to process,” says Spencer. It takes sleep to provide the space needed to sift through the days’ experiences, and make permanent those that matter.
Studies show that sleep enhances your memory of experiences, and the effect is multiplied for experiences with the stamp of emotion. In fact, the memory-consolidation process that occurs during sleep is so effective that some scientists, including Pace-Schott and Spencer, have suggested that it could be used to treat PTSD. Spencer posits that keeping someone from sleep following a traumatic event could be good in the long run. “If you force yourself to stay awake through a period of insomnia,” Spencer says, “the [traumatic] memory and emotional response will both decay.”
On the flip side, when it comes to the majority of the negative things we experience in life—the things that aren’t necessarily traumatizing like, say, a fight with your significant other—we want to go to sleep, because that protects the memory and emotional response.
And Pace-Schott points out that sleep disruption may prevent consolidation of potentially therapeutic memories, sometimes termed 'fear extinction' memories. These are memories that can dull the effect of a traumatic experience by creating more positive associations with specific triggers.] This means that improving sleep quality following traumatic events may be crucial to preventing PTSD.
Ever wonder why little kids nap so much? Researchers believe that it’s not just because they’ve been running around all day—it’s also due to the fact their short-term memory storage space is so small, and they constantly need to unload experiences and consolidate memories more often. One recent study, in fact, found that “distributed sleep” (a.k.a. napping) is critical for learning at an early age. The nap that follows a 4 year-old child getting burnt on a hot stove should help him learn from the experience.
Similarly, the nap following a fight with my wife should, ideally, teach me how to better manage interpersonal conflict. The benefits of sleep on memory don’t go away.
When we wake up from sleep, we feel different. It's not just that time has passed; we've undergone a real chemical response. When we sleep, all the stress systems in our body are damped down, letting it relax, so that tenseness you felt, the sickness in your stomach, the frayed nerves, will all be gone in the morning. “It’s almost like we are different people when we wake up,” says Pace-Schott.
One particular neurochemical, called orexin, may hold the key to the puzzle. Orexin, which was discovered only about 15 years ago, is unique in that it plays a very clearly defined dual role in the body. First and foremost, it’s a crucial element in your daily sleep/wake rhythm. You get a boost of the stuff when you wake up, and it drops before you go to sleep. Studies in rats show that if you take all of an animal’s orexin away, it can no longer effectively control sleeping and waking. Since its discovery, orexin has become one of the key diagnostic criteriafor determining narcolepsy—those with the sleep disorder essentially have none of the neurochemical.
And then there’s the second function: It’s part of the stress response system.
“The orexin system is absolutely hardwired into the sympathetic nervous system,” says Philip L. Johnson, a neuroscientist at the Indiana University School of Medicine. If everything is working normally, when you are faced with a stressful situation, your orexin system kicks in and triggers the stress responses that you expect: fight or flight.
In other words, the same exact neural pathway that handles wakefulness (we can’t even get out of bed without orexin kicking in) also handles a key aspect of our stress response.
Think about this: while narcoleptics do sometimes just nod off randomly, strong emotions are, most often, connected to onset of sleep. It’s counterintuitive, but it’s true, says Johnson. For many narcoleptics, strong emotions associated with stress can cause a complete collapse.
Of course, this should sound familiar—it’s not so different than what happens when Brad, LeAnna, Daniel, I, and so many others go head to head with stress. The science on this is still in its infancy, and it remains unclear exactly what’s going on at a chemical level here, but there does seem to be some connection.
In the meantime, sleep doesn’t seem too bad. The problem may still be there when you awake, but you’ll have a better understanding of it, and hopefully, a clear slate to handle it.
Can stress in the earliest days of our lives set us up for how we cope and our preferences to eating comfort food? This study finds evidence for this.
Apr. 7, 2013 — Researchers at the University of Calgary's Hotchkiss Brain Institute have discovered that stress circuits in the brain undergo profound learning early in life. Using a number of cutting edge approaches, including optogenetics, Jaideep Bains, PhD, and colleagues have shown stress circuits are capable of self-tuning following a single stress. These findings demonstrate that the brain uses stress experience during early life to prepare and optimize for subsequent challenges.
The team was able to show the existence of unique time windows following brief stress challenges during which learning is either increased or decreased. By manipulating specific cellular pathways, they uncovered the key players responsible for learning in stress circuits in an animal model. These discoveries culminated in the publication of two back-to-back studies in the April 7 online edition of Nature Neuroscience.
"These new findings demonstrate that systems thought to be 'hardwired' in the brain, are in fact flexible, particularly early in life," says Bains, a professor in the Department of Physiology and Pharmacology. "Using this information, researchers can now ask questions about the precise cellular and molecular links between early life stress and stress vulnerability or resilience later in life."
Stress vulnerability, or increased sensitivity to stress, has been implicated in numerous health conditions including cardiovascular disease, obesity, diabetes and depression. Although these studies used animal models, similar mechanisms mediate disease progression in humans.
"Our observations provide an important foundation for designing more effective preventative and therapeutic strategies that mitigate the effects of stress and meet society's health challenges," he says.
Can the stress mom's experience while pregnant impact their children into adulthood. There is growing evidence that a baby's wiring and predisposition is strongly influenced by the emotional health of their mother. Read on to discover how.
Nov. 14, 2012 — Children whose mothers were overly stressed during pregnancy are more likely to become victims of bullying at school.
New research from the University of Warwick shows stress and mental health problems in pregnant women may affect the developing baby and directly increases the risk of the child being victimized in later life.
The study has been published in theJournal of Child Psychology and Psychiatry and is based on 8,829 children from the Avon Longtitudinal Study of Parents and Children (ALSPAC).
Professor Dieter Wolke, Professor of Developmental Psychology at University of Warwick and Warwick Medical School headed up the study.
He said: "This is the first study to investigate stress in pregnancy and a child's vulnerability to being bullied. When we are exposed to stress, large quantities of neurohormones are released into the blood stream and in a pregnant woman this can change the developing fetus' own stress response system.
"Changes in the stress response system can affect behaviour and how children react emotionally to stress such as being picked on by a bully. Children who more easily show a stress reaction such as crying, running away, anxiety are then selected by bullies to home in to."
The research team identified the main prenatal stress factors as severe family problems, such as financial difficulty or alcohol/drug abuse, and maternal mental health.
Professor Wolke added: "The whole thing becomes a vicious cycle, a child with an altered stress response system is more likely to be bullied, which affects their stress response even further and increases the likelihood of them developing mental health problems in later life."
Does depression make quitting smoking more difficult? This study seems to find that treating depression does help people quit smoking. Read more to find out.
Sep. 19, 2013 — Studies have shown that people with depression are about twice as likely to smoke cigarettes as people without depression and they are less likely to successfully quit than smokers without depression. A new evidence review in The Cochrane Library finds that depressed smokers may stop smoking longer and benefit overall from mood management interventions after they quit smoking.
“Health professionals should encourage their smoking patients with depression to use a smoking cessation intervention that includes a psychosocial mood management component,” said the study’s lead author Regina van der Meer, MPH, a researcher at the Dutch Expert Centre on Tobacco Control.
The researchers studied 49 randomized controlled trials, including 33 trials that focused on smoking cessation with a mood management element for those with current or past depression. The analysis compared both smoking cessation programs using psychosocial interventions, like counseling or exercise, and those using bupropion, an antidepressant to standard non-smoking programs.
When psychosocial components were added, smokers were able to stop smoking for longer periods. While bupropion was effective for those with a history of depression, it was not found to be effective for smokers with current depression.
Gregory L. Kirk, M.D., director of Rocky Mountain Psychiatry Consultants, LLC in Denver, who agreed with the review’s findings, emphasized that smokers with depression, past or present, have more medical problems from smoking and higher death rates from smoking-related illnesses.
“In a standard smoking cessation program, people with depression are more likely to have negative mood changes from nicotine withdrawal, but the non-depressed group can experience mood states as well. But when depressed smokers quit, depression symptoms may actually improve. This makes it all the more critical to understand this high-risk group of smokers and what helps them quit tobacco,” he said.
Can depression lead to death in people with diabetes? According to new research depression causes people with diabetes to follow a cycle of hopelessness, poor self care and increased risk of other health conditions. This in turn leads to increased mortality. This study urges integrative care to address the depression in individuals with diabetes.
Feb. 21, 2013 — People living with diabetes who also have untreated depression are at increased risk of death, according to a new evidence review in General Hospital Psychiatry.
More than 42,000 patients with type 1 or type 2 diabetes and depression were analyzed in the review. The reviewers discovered that depression was associated with a 1.5 fold increase in the risk of dying. In four of the studies reviewed, co-morbid depression was linked to about a 20 percent higher risk of cardiovascular death for people with diabetes.
Diabetes affects 25.8 million people in the U.S., according to the 2011 National Diabetes Fact Sheet, and about 30 percent of these people also experience symptoms of depression.
"Depression consistently increased the risk of mortality across virtually all studies," said Mijung Park, Ph.D., lead author and assistant professor at the University of Pittsburgh School of Nursing. "We can now postulate that the harmful effect of depression is universal to individuals with diabetes."
Todd Brown, M.D., associate professor of medicine and epidemiology at Johns Hopkins University in Baltimore, said it is very common to see a patient go into a downward spiral when obesity-related co-morbidities, such as diabetes, high blood pressure, obesity and depression converge.
"Obesity can lead to worsening metabolic status that can lead to hopelessness and decreased physical activity, which in turns worsens obesity, and the cycle continues," he explained.
The encouraging news is that depression is a highly treatable condition, said Park. Because depression can make diabetes self-care more difficult and lessen quality of life, she suggested that depression treatment should be included in overall diabetes care strategies.
Having "motors" in the brain not working properly might lead to less serotonin getting to where it needs to go, in turn leading to higher levels of anxiety. This is promising new research that can lead to medication that "fixes" the "motors" and restores serotonin pathways and levels. Read article below for further details.
Feb. 7, 2013 — When motors break down, getting where you want to go becomes a struggle. Problems arise in much the same way for critical brain receptors when the molecular motors they depend on fail to operate. Now, researchers reporting in Cell Reports, a Cell Press publication, on February 7, have shown these broken motors induce stress and anxiety in mice. The discovery may point the way to new kinds of drugs to treat anxiety and other disorders.
The study in mice focuses on one motor in particular, known as KIF13A, which, according to the new evidence, is responsible for ferrying serotonin receptors. Without proper transportation, those receptors fail to reach the surface of neurons and, as a result, animals show signs of heightened anxiety.
In addition to their implications for understanding anxiety, the findings also suggest that defective molecular motors may be a more common and underappreciated cause of disease.
"Most proteins are transported in vesicles or as protein complexes by molecular motors," said Nobutaka Hirokawa of the University of Tokyo. "As shown in this study, defective motors could cause many diseases."
Scientists know that serotonin and serotonin receptors are involved in anxiety, aggression, and mood. But not much is known about how those players get around within cells. When Hirokawa's team discovered KIF13A at high levels in the brain, they wondered what it did.
The researchers discovered that mice lacking KIF13A show greater anxiety in both open-field and maze tests and suggest that this anxious behavior may stem from an underlying loss of serotonin receptor transport, which leads to a lower level of expression of those receptors in critical parts of the brain.
"Collectively, our results suggest a role for this molecular motor in anxiety control," the researchers wrote. Hirokawa says the search should now be on for anti-anxiety drug candidates aimed at restoring the brain's serotonin receptor transport service.
