文章大意:本文是说明文。文章主要研究人员发现,经常打盹的成年人更容易患高血压和中风。但这并不意味着小睡会导致这些健康问题——相反,小睡可能是由于不健康的行为造成的。研究人员发现,经常打瞌睡的人中有很高比例的人有吸烟、每天饮酒、失眠以及其他可能导致健康相关问题的因素。
A new study published on Monday in an American Heart Association journal Hypertension, examined 360,000 participants who provided blood, saliva (唾液)and urine samples, as well as detailed information about their lifestyles. Researchers found that adults who napped (打盹) often were more likely to develop high blood pressure and have a stroke (中风). But that doesn’t mean napping causes these health issues-instead, napping may be due to unhealthy behaviors. The researchers found that a high percentage of frequent nappers reported cigarette smoking, daily drinking, sleeplessness and other factors that could cause health-related issues.
Dr. Margaret Blattner, a clinical instructor, from the department of neurology at Beth Israel Deaconess Medical Center, tells PEOPLE that frequent or long daytime naps can have a bad effect on healthy nighttime sleep. Napping during the day may make it harder to fall asleep at night or cause nighttime sleep to become fragmented (支离破碎的) and missing out on nighttime sleep can cause severe daytime sleepiness.
“Often, naps continuing long are less beneficial than more brief daytime naps; people often wake up unrefreshed after a long nap,” she adds. “Additionally, long daytime naps take away time from other healthy things that people enjoy during the day: spending time with family, enjoying hobbies, and exercise.” When napping during the day becomes unpredictable, uncontrollable, or stops an individual from finishing what they need or want to do, it could show a possible sleep disorder.
Blattner believes that taking naps can also be beneficial. “Napping is not always a cause for concern. Taking a nap can be refreshing and enjoyable,” she says. “The key is, are you missing out on things that you enjoy because you are too sleepy to stay awake-that can indicate a problem-or does the nap help you get more out of your day?”
“Taking a brief nap can feel refreshed, reduce stress, and improve focus. Early afternoon is a good time to nap, as this agrees with a physical circle drop in energy,” Blattner continues. “However, napping too late into the afternoon or evening may have a bad effect on nighttime sleep quality and make it harder to fall asleep.”
