Stressing Fitness

"Research shows it's possible to cushion yourself against stress, and the tactics we're using with soldiers also apply to real folks and more common types of anxiety." Key to the recent breakthroughs is a much clearer picture of how destructive stress can be. Persistent anxiety can kill neurons in brain structures concerned with memory and decisionmaking, and such damage is even visible on brain scans.

Fortunately, experts are learning that all along the continuum—from severe anxiety disorders to garden-variety worry—coping and even prevention tactics are highly effective. Here's what new PTSD science can teach all of us about outsmarting stress. If these solutions work for soldiers in Iraq and Afghanistan, they can certainly help the rest of us on the home front.

Researchers are learning that exercise doesn't just soothe stress, it also fortifies brain cells so they're less vulnerable to anxiety in the future.

Cellphones, which in the last few years have become full-fledged computers with high-speed Internet connections, let people relieve the tedium of exercising, the grocery store line, stoplights or lulls in the dinner conversation.

The technology makes the tiniest windows of time entertaining, and potentially productive. But scientists point to an unanticipated side effect: when people keep their brains busy with digital input, they are forfeiting downtime that could allow them to better learn and remember information, or come up with new ideas.

“Almost certainly, downtime lets the brain go over experiences it’s had, solidify them and turn them into permanent long-term memories,” said Loren Frank, assistant professor in the department of physiology at the university, where he specializes in learning and memory. He said he believed that when the brain was constantly stimulated, “you prevent this learning process.”

Research suggests that as many as 25% of children in the United States report being subjected to cyberbullying, which is the use of technological devices to deliberately harass or harm other people through e-mail, text messaging, instant messaging, cell phones and online social networking sites.

And at least 20% of teens say they've engaged in sexting, which is the sending of sexually explicit photos via cell phones.

We should move toward food-based instead of nutrient-based dietary guidelines.

we should be promoting whole foods, not specific nutrients which push consumers toward processed products

While nutritional science at the nutrient and molecular level is fascinating and making incredible progress, I think the most effective way to reverse health epidemics is to focus on education about foods and changing the nutritional environment.

Stress caused by social situations, such as giving a speech or going to a job interview, can affect some people's immune system in ways that harm their health, researchers have found.The study included 124 volunteers who were purposely put into awkward social situations. Those who exhibited greater neural sensitivity to social rejection also had greater increases in inflammatory activity when exposed to social stress.

The findings provide "further evidence of how closely our mind and body are connected. We have known for a long time that social stress can 'get under the skin' to increase risk for disease, but it's been unclear exactly how these effects occur. To our knowledge, this study is the first to identify the neurocognitive pathways that might be involved in inflammatory responses to acute social stress," Slavich said.

Surveys by Mental Health America and other researchers have found that people affected by the lousy economy have a higher risk for mental illness, especially such conditions as depression and anxiety.

The Mental Health America survey found that unemployed people were four times as likely as people with jobs to report symptoms consistent with severe mental illness.But the harmful mental effects of the economy aren't limited to the unemployed. People whose jobs were changed by the economic downturn -- those who went through involuntary job changes or had their hours or pay cut at work -- were twice as likely to have symptoms consistent with severe mental illness, the survey found.It also found that unemployed people were four times more likely to think of harming themselves and twice as likely to report substance or alcohol abuse or worries about their mental health.

At a time when they need professional help more than ever, many people have less access to it, the survey also revealed. About half of the survey participants who were unemployed said they had difficulty obtaining health care. Of those who hadn't spoken to a doctor about their mental health concerns, 42% said it was because the care was too expensive or they didn't have insurance to cover it.

Drinking wine in moderate amounts may reduce the risk of decline in thinking skills in some people and may even protect against dementia, a new study shows.

women who reported drinking wine at least four times over a two-week period were at reduced risk of scoring poorly on the tests, compared with women who had less than one drink during the period. In addition, women who didn't drink any alcohol scored lowest on the tests. The average age of people in the study was 58, and none had suffered a stroke.

Eating some kinds of berries can help your brain stay healthy by helping to clean out toxic material linked to mental decline, including age-related memory loss, a new study shows.

Experts have long known that as the body ages it suffers “oxidative damage” and is less likely to be able to protect itself against cancer, heart disease and age-related mental decline.

But Poulose and his colleague found that strawberries, blueberries and acai berries activate brain cells called microglia. These cells, according to the ACS, act as the brain’s “housekeeper.” In a process called autophagy, they clean out “biochemical debris that would otherwise interfere with brain function.”

People at risk for type 2 diabetes are also more likely to have brain abnormalities associated with Alzheimer's disease, according to a new study from Japan. The study is the latest evidence of a diabetes-dementia link.

The researchers found that men and women in their 60s with higher-than-average levels of blood sugar (glucose) or insulin -- two signs of type 2 diabetes -- are between three and six times more likely to have certain protein deposits in their brains a decade or more later, according to the study, which appears in the journal Neurology.

Alzheimer's disease affects as many as 5 million people in the U.S., and the cause is largely unknown (although genes play a role). About 24 million people in the U.S. have diabetes, and about 90 percent of those have type 2.

Although mind-bending drugs such as psilocybin are still used most often by people looking to get high, researchers around the country have begun to explore whether these and other illegal drugs can help treat intractable depression, anxiety, and other mental-health problems.

n the past month alone, studies have been published on the benefits of MDMA (better known as Ecstasy) in people with post-traumatic stress disorder and on the fast-acting antidepressive effects of the club drug ketamine (aka "Special K").

But research into the potential benefits of psychedelic drugs ground to a halt in the early 1970s, after the federal government criminalized LSD and psilocybin -- and after the drugs were eagerly adopted by college students and the hippie counterculture. "These studies had to be shut down because of the cultural reaction,"

Eating more oily fish like sardines, salmon and yellowtail could help teenage boys feel less blue, suggests a new Japanese study. The same does not appear to hold for teen girls, however.

People with metabolic syndrome -- a cluster of risk factors for heart disease, stroke and type 2 diabetes -- have a better chance of reversing it if they stick to a healthy diet, a new study shows.

A person is considered to have metabolic syndrome if they have three or more of the following risk factors: excess belly fat; high triglyceride levels (a harmful blood fat); low levels of "good" HDL cholesterol; high blood pressure; and either high blood sugar levels or type 2 diabetes.

According to the National Heart Lung and Blood Institute (NHLBI), having metabolic syndrome doubles a person's risk of heart disease and quintuples their risk of developing type 2 diabetes. Nearly a quarter of US adults have the metabolic syndrome.

It was a primitive trip with a sophisticated goal: to understand how heavy use of digital devices and other technology changes how we think and behave, and how a retreat into nature might reverse those effects.

"Even if you're aerobically fit, it helps to be limber, too, so your body can easily adapt to physical stressors,"

Although countless studies have shown how beneficial exercise is for your body and mind (it may do everything from reducing the risk of some cancers to helping improve memory), less attention has been paid to flexibility.

"Flexibility is the third pillar of fitness, next to cardiovascular conditioning and strength training
