17 Surprising Reasons You’re Stressed Out

April 13, 2015 / / 0 Comments





Excerpt from huffingtonpost.com
By Amanda MacMillan


You're probably all too aware of the major sources of stress in your life -- money, your terrible commute, the construction workers who start jackhammering at 5 a.m. But stress and anxiety don't have to just come from obvious or even negative sources. "There are plenty of chronic strains and low-grade challenges that don't necessarily overwhelm you in the moment, but almost take more of a toll in the long run," says Scott Schieman, Ph.D., professor of sociology at the University of Toronto. These are some of unexpected reasons why you might feel anxious or agitated. By recognizing them for what they are, says Schieman, you can better prepare to cope.

1. Your Significant Other
Even if you have a blissfully happy relationship with your live-in partner or spouse, you're both bound to do things that get on each other's nerves. "Early in the relationship, it's usually about space and habits -- like whether you squeeze the toothpaste from the middle or the bottom of the tube," says Ken Yeager, Ph.D., associate professor of psychiatry at the Ohio State University Wexner Medical Center. "Later on, you might clash over parenting style or financial issues, and finding a unified front to face these issues together." So what's the key to surviving and thriving in your life together? Finding balance, says Yeager: spending the right amount of time together (not too much and not too little), making compromises, keeping communication open and honest, and remembering to acknowledge what you love about each other on a daily basis.

2. Everyday Annoyances
We're told not to sweat the small stuff, but sometimes it's the little things that have the biggest impact on our mood: the never-ending phone calls with your insurance company, the rude cashier at the grocery store, the 20 minutes you lose looking for a parking space. "We let these things bother us because they trigger unconscious fears," says Yeager -- fears of being seen as irresponsible, of being bullied or embarrassed, or of being late all the time, for example. "Sometimes you need to take a step back and realize that you're doing the best you can given the circumstances." 

3. Other People's Stress
Stress is contagious, according to a 2014 German study: In a series of experiments, most participants who simply observed others completing a stressful task experienced an increase themselves in production of the stress hormone cortisol -- a phenomenon known as empathic stress. You can also experience stress when someone you know is affected by a traumatic event, like a car crash or a chronic illness. "You start to worry, 'Oh my gosh, could that happen to me?'," says Yeager. "We tend not to think about these things until they hit close to home."

4. Social Media social media
It may seem like Facebook is the only way you keep up with the friends you don't see regularly -- which, during particularly busy times, can be just about all of them. The social network also has a downside, according to a 2015 study from the Pew Research Center: It can make you aware of stressful situations in your friends' lives, which in turn can add more stress to your life. The Pew report didn't find that social media users, overall, had higher levels of stress, but previous studies have suggested that frequent social-media use can be associated with negative body image and prolonged breakup pain.

5. Distraction
A distraction can be a good thing then when it takes your mind off of a stressful situation or difficult decision, like when you take a break from work to meet a friend for lunch. But it works the other way, as well: When you're so busy thinking about something else that you can't enjoy what's going on around you, that kind of distraction can be a recipe for stress. Practicing mindfulness gives you brain the refresh it needs, says Richard Lenox, director of the Student Counseling Center at Texas Tech University. Paying full attention to your surroundings when you're walking and driving can help, he adds. "Stress and anxiety tend to melt away when our mind is focused on the present." 

6. Your Childhood
Traumatic events that happened when you were a kid can continue to affect your stress levels and overall health into adulthood. A 2014 University of Wisconsin-Madison study found that these childhood experiences may actually change parts of the brain responsible for processing stress and emotion. The way you were raised can also have a lasting impact on your everyday angst, suggests a 2014 Johns Hopkins University study. Researchers found that children of parents with social anxiety disorders are more likely to develop "trickle-down anxiety" -- not simply because of their genes, but because of their parents' behaviors toward them such as a lack of warmth and emotion, or high levels of criticism and doubt.

7. Tea And Chocolate
You probably know to take it easy on the coffee when you're already feeling on edge. "Caffeine is always going to make stress worse," says Yeager. But you may not think as much about drinking several cups of tea at once, or chowing down on a bar of dark chocolate -- both of which can contain nearly as much caffeine as a cup of joe. "Chocolate is a huge caffeine source," says Yeager. "I know people who don't drink coffee but they'll eat six little candy bars in a two-hour period because they want the same kind of jolt." Too much caffeine, in any form, can cause problems with sleep, digestion, and irritability. 

8. Your Expectations woman trail running
When things don't go the way you've planned, do you tend to get upset and act defensively, or do you roll with the punches and set off on a new plan? If it's the former, you could be contributing to a mindset of pessimism and victimization that will slowly wear you down, even when things may not be as bad as they seem. "Your level of serenity is inversely proportionate to your expectations," says Yeager. That doesn't mean you shouldn't set ambitious goals for yourself or settle for less than what you want, of course, but being realistic about what's truly possible is important, as well.

9. Your Reaction To Stress
If you tend to deal with stressful situations by working long hours, skipping your workouts, and bingeing on junk food, we've got some bad news: You're only making it worse. "We know that physical activity and healthy foods will help your body better deal with stress, and yet we often avoid them when we need them the most," says Yeager. "People really need to think about this downward spiral we get into and work harder to counteract it."

10. Multitasking
Think you're being super efficient by tackling four tasks at once? Chances are you're not -- and it's only decreasing your productivity while increasing your stress. A 2012 University of Irvine study, for example, found that people who responded to emails all day long while also trying to get their work done experienced more heart-rate variability (an indicator of mental stress) than those who waited to respond to all of their emails at one time. Focusing on one task at a time can ensure that you're doing that job to the best of your abilities and getting the most out of it, so you won't have to worry about or go back and fix it later, says Schieman. And don't worry: You'll have enough time to do it all. In fact, you may discover you have more time than you thought.

11. Your Favorite Sport
Watching a tight game of college hoops can stress you out -- even if your alma mater wins. "The body doesn't distinguish between 'bad' stress from life or work and 'good' stress caused by game-day excitement," says Jody Gilchrist, a nurse practitioner at the University of Alabama at Birmingham’s Heart and Vascular Clinic. Watching sports can even trigger the body's sympathetic nervous system, releasing adrenaline and reducing blood flow to the heart. Those temporary consequences aren't usually anything to be concerned about, but over time, chronic stress can lead to high blood pressure and increased disease risk. And, of course, it doesn't help if you're adding alcohol and binge-eating to a situation that's already stressful on your body. You may not be able to control the outcome of the game, says Gilchrist, but you can limit its effects on your own body. 

12. Digital Devices laptop in bed
Whether you're using it for work or play, technology may play a large role in your mental health, says Yeager. Using computers or e-readers too close to bedtime could lead to sleep problems, he says, and spending too much time virtually socializing can make real-life interactions seem extra stressful. (Plus, texting doesn't trigger the same feel-good hormones as face-to-face talk does.) Then there's the dreaded "work creep," says Schieman, when smartphones allow employees to be tethered to their jobs, even during off-hours. "People say they're only going to check email for an hour while they're on vacation, but the problem with email is that they're filled with responsibilities, new tasks, and dilemmas that are going to be hard to compartmentalize and put out of your head once that hour is up."

13. Your (Good) Health
While it may not be as stressful as having a chronic illness or getting bad news at the doctor's office, even people in the best shape of their lives worry about their bodies, their diets, and their fitness levels. In fact, people who take healthy living to an extreme may experience some rather unhealthy side effects. People who follow low-carb diets, for example, are more likely to report being sad or stressed out, while those on any kind of restrictive meal plan may feel more tired than usual. And it's not unheard of for someone to become obsessed with healthy eating (known as orthorexia) or working out (gymorexia). Like any form of perfectionism, these problems can be stressful at best, and extremely dangerous at worst.

14. Housework
Does folding laundry help you feel calm, or does it make your blood boil? If you're in a living situation where you feel you're responsible for an unfair share of work, even chores you once enjoyed may start to feel like torture. "Dividing up housework and parenting responsibilities can be tricky, especially if both partners work outside the home," says Schieman. "And whether you define that division of labor as equal or unequal can really change your attitude toward it."

15. Uncertainty
Stress can be defined as any perceived or actual threat, says Yeager, so any type of doubt that's looming over you can contribute to your anxiety levels on a daily basis. "When you know something could change at any minute, you always have your guard up and it's hard to just relax and enjoy anything." Financial uncertainty may be the most obvious stressor -- not being sure if you'll keep your job during a round of layoffs, or not knowing how you'll pay your credit card bill. Insecurities in other areas of life, like your relationship or your housing status, can eat away at you too.

16. Your Pet bulldog puppy
No matter how much you love your furry friends, there's no question that they add extra responsibility to your already full plate. Even healthy animals need to be fed, exercised, cleaned up after, and given plenty of attention on a regular basis -- and unhealthy ones can be a whole other story. "Pets can be the most positive source of unconditional love, but at the same time they require an extreme amount of energy," says Yeager. People also tend to underestimate the stress they'll experience when they lose a pet. "I've had people in my office tell me they cried more when their dog died than when their parent died. It's a very emotional connection."

17. Your Education
Having a college degree boosts your odds of landing a well-paying job, so although you're less likely to suffer from money-related anxiety, your education can bring on other types of stress, according to a 2014 study by Schieman and his University of Toronto colleagues. His research found that highly educated people were more likely to be stressed out thanks to job pressures, being overworked, and conflicts between work and family. "Higher levels of authority come with a lot more interpersonal baggage, such as supervising people or deciding whether they get promotions," says Schieman. "With that type of responsibility, you start to take things like incompetency and people not doing their jobs more personally, and it bothers you more."

Did natural selection make the Dutch the tallest people on the planet?

April 9, 2015 / / 0 Comments

Excerpt from news.sciencemag.org
ByMartin Enserink

AMSTERDAM—Insecure about your height? You may want to avoid this tiny country by the North Sea, whose population has gained an impressive 20 centimeters in the past 150 years and is now officially the tallest on the planet. Scientists chalk up most of that increase to rising wealth, a rich diet, and good health care, but a new study suggests something else is going on as well: The Dutch growth spurt may be an example of human evolution in action.
The study, published online today in the Proceedings of the Royal Society B, shows that tall Dutch men on average have more children than their shorter counterparts, and that more of their children survive. That suggests genes that help make people tall are becoming more frequent among the Dutch, says behavioral biologist and lead author Gert Stulp of the London School of Hygiene & Tropical Medicine.

"This study drives home the message that the human population is still subject to natural selection," says Stephen Stearns, an evolutionary biologist at Yale University who wasn't involved in the study. "It strikes at the core of our understanding of human nature, and how malleable it is." It also confirms what Stearns knows from personal experience about the population in the northern Netherlands, where the study took place: "Boy, they are tall."

For many years, the U.S. population was the tallest in the world. In the 18th century, American men were 5 to 8 centimeters taller than those in the Netherlands. Today, Americans are the fattest, but they lost the race for height to northern Europeans—including Danes, Norwegians, Swedes, and Estonians—sometime in the 20th century.

Just how these peoples became so tall isn't clear, however. Genetics has an important effect on body height: Scientists have found at least 180 genes that influence how tall you become. Each one has only a small effect, but together, they may explain up to 80% of the variation in height within a population. Yet environmental factors play a huge role as well. The children of Japanese immigrants to Hawaii, for instance, grew much taller than their parents. Scientists assume that a diet rich in milk and meat played a major role.

The Dutch have become so much taller in such a short period that scientists chalk most of it up to their changing environment. As the Netherlands developed, it became one of the world's largest producers and consumers of cheese and milk. An increasingly egalitarian distribution of wealth and universal access to health care may also have helped.

Still, scientists wonder whether natural selection has played a role as well. For men, being tall is associated with better health, attractiveness to the opposite sex, a better education, and higher income—all of which could lead to more reproductive success, Stulp says.
Yet studies in the United States don't show this. Stulp's own research among Wisconsinites born between 1937 and 1940, for instance, showed that average-sized men had more children than shorter and taller men, and shorter women had more children than those of average height. Taken together, Stulp says, this suggests natural selection in the United States pulls in the opposite direction of environmental factors like diet, making people shorter instead of taller. That may explain why the growth in average American height has leveled off.

Stulp—who says his towering 2-meter frame did not influence his research interest—wondered if the same was true in his native country. To find out, he and his colleagues turned to a database tracking key life data for almost 100,000 people in the country's three northern provinces. The researchers included only people over 45 who were born in the Netherlands to Dutch-born parents. This way, they had a relatively accurate number of total children per subject (most people stop having children after 45) and they also avoided the effects of immigration.

In the remaining sample of 42,616 people, taller men had more children on average, despite the fact that they had their first child at a higher age. The effect was small—an extra 0.24 children at most for taller men—but highly significant. (Taller men also had a smaller chance of remaining childless, and a higher chance of having a partner.)  The same effect wasn't seen in women, who had the highest reproductive success when they were of average height.  The study suggests this may be because taller women had a smaller chance of finding a mate, while shorter women were at higher risk of losing a child.

Because tall men are likely to pass on the genes that made them tall, the outcome suggests that—in contrast to Americans—the Dutch population is evolving to become taller, Stulp says. "This is not what we've seen in other studies—that's what makes it exciting," says evolutionary biologist Simon Verhulst of the University of Groningen in the Netherlands, who was Stulp's Ph.D. adviser but wasn't involved in the current study. Verhulst points out that the team can't be certain that genes involved in height are actually becoming more frequent, however, as the authors acknowledge.

The study suggests that sexual selection is at work in the Dutch population, Stearns says: Dutch women may prefer taller men because they expect them to have more resources to invest in their children. But there are also other possibilities. It could be that taller men are more resistant to disease, Stearns says, or that they are more likely to divorce and start a second family. "It will be a difficult question to answer.”

Another question is why tall men in Holland are at a reproductive advantage but those in the United States are not. Stulp says he can only speculate. One reason may be that humans often choose a partner who's not much shorter or taller than they are themselves. Because shorter women in the United States have more children, tall men may do worse than those of average height because they're less likely to partner with a short woman.

In the end, Stearns says, the advantage of tall Dutchmen may be only temporary. Often in evolution, natural selection will favor one trend for a number of generations, followed by a stabilization or even a return to the opposite trend. In the United States, selection for height appears to have occurred several centuries ago, leading to taller men, and then it stopped. "Perhaps the Dutch caught up and actually overshot the American men," he says.
