5个压力神话被揭穿
5 Myths About Stress, Debunked

In today's world, feeling stressed out is the rule, not the exception. For most of us, learning more about how to handle stress is a crucial step toward better physical and psychological health.
Unfortunately, a lot of what passes for common wisdom about stress turns out not to be so wise after all. Watch out for these five common myths.
Myth: Stress makes you pessimistic and cautious.
神话：压力使你悲观和谨慎
Reality: Stress is often associated with bad experiences, so you might think it would bias your thinking in a negative direction. However, a recent article in Current Directions in Psychological Science concluded that the opposite is true: When people are put under stress in studies—for example, by being asked to hold their hand in ice water or give a speech—they begin paying more attention to positive information.
According to the article’s authors at the University of Southern California, this finding has important implications for decision-making in everyday life. For example, let’s say you’re trying to lose weight and deciding whether to have chocolate cake for dessert. After a stressful day, you may be more likely to focus on how good the cake will taste and to discount the unwanted calories it contains. If you're not aware of this tendency and don't compensate for it, you might make some decisions you later regret.
Myth: Chronic stress is linked to heart disease, not brain disease.
神话：持续压力会引起心脏疾病，而不是大脑疾病
Reality: The relationship between stress and heart disease still isn’t fully understood. But it’s known that chronic stress causes an increase in heart rate and blood pressure that might damage artery walls over time. The risks don’t stop there, however. Stress affects your whole body, including your brain.
One recent line of research suggests that frequent stress may even boost the risk for Alzheimer’s disease. A new study headed by scientists at the University of California at San Diego showed that repeated stress triggered brain changes in mice that were similar to the abnormal clumps of protein seen in the brains of Alzheimer’s patients. The changes were most pronounced in the hippocampus. In humans, this part of the brain plays a key role in memory and is hard hit by Alzheimer’s disease.
Myth: Stress management is about controlling difficult situations.
神话：压力管理就是控制艰难处境
Reality: Some situations that give rise to stress are under your control, but many are not. You can’t control bad weather, traffic jams, your boss’s crankiness, a stranger’s rudeness, or an infinitely long list of other situations and events. But that’s okay, because you can manage your reaction to these things, and that’s what many stress management strategies are designed to do.
One way to stop stress is by reappraising a difficult situation as a challenge rather than a threat. For example, when you're given a tough new assignment at work, you can make a conscious choice to think about it as an opportunity to grow in your job—not a chance to fall flat on your face. A new study showed that this may come more easily if you’re naturally open to new experiences and less easily if you’re prone to anxiety. But it’s a habit of mind that anyone can cultivate with practice.
Myth: A couple of drinks will help you de-stress.
神话：喝几杯可以减压
Reality: A study in Alcoholism: Clinical and Experimental Research showed why alcohol doesn’t work very well as a stress relief strategy. In the study, University of Chicago researchers first put men under stress with a public speaking task. Then they gave the men either the equivalent of two drinks of alcohol or a placebo by IV and measured the results. Although alcohol dampened the men's hormonal responses to stress, it actually prolonged their subjective feelings of tension.
To make matters worse, the same study showed that stress could reduce the pleasant effects of alcohol or increase the craving for more of it. In the real world, this might encourage drinking too much—and that can lead to a whole host of bad choices that only multiply stress.
Myth: Everyone needs to meditate (or do yoga or take long walks).
神话：每人都需要冥想（或做瑜伽或长跑）
Reality: Another way to counter stress is by learning effective ways to relax your body and calm your mind. For example, you might take several deep breaths, go for a walk or bike ride, practice mindfulness or meditation, do yoga or tai chi, call a supportive friend, or spend time in nature. But it’s not a one-size-fits-all solution. The key is finding strategies that suit your personality and lifestyle.
There are a few universal guidelines, however. For optimal stress relief, it’s essential to get regular physical activity and adequate sleep. Recent research suggests that REM sleep—the stage during which dreaming occurs—may be particularly important. In the REM state, emotional memories are reprocessed, but stress hormones are suppressed. This may take some of the edge off painful memories, making it easier to cope the next day.
