不定项选择题 While one in five people in China have symptoms of a sleep disorder, only one in 10 who exercise regularly report problems sleeping, according to a study released on Thursday by the Chinese Sleep Research Society.
The COVID-19 epidemic has also deepened the divide in sleeping patterns between couch potatoes and regular exercisers, as people who lead sedentary lifestyles and often sleep badly are less inclined to work out due to travel restrictions, causing further kerfuffle to their circadian rhythms, the study said.
Experts said the results provide a strong impetus for people suffering persistent sleep disorders, such as insomnia, irregular breathing and frequent nightmares, to incorporate more exercise into their lives or upgrade their workout regimes.
Sleep disorders and insufficient sleeping hours have become more prominent in China in recent years. Acute insomnia turning into chronic insomnia has to do with a common mistake people make after a night or two of poor sleep. Even among those who have struggled for years with insomnia, many continue to employ this same counterproductive strategy.
Experts said that the common, insomnia-perpetuating error that most people commit is that they try to make up for lost sleep; they take naps, they go to bed early, and they sleep in late. “All of this contributes to sleep dysregulation.” Elliot, one of the experts suggested that they should not try to make up for lost sleep. Instead, they should stick to their usual sleep-wake routine even on days when they’re exhausted and dying for a nap or a sleep-in. “I tell people to be awake in the service of sleep,” he says. “If you build up enough sleep debt, sooner or later that will be enough to force you into deep and prolonged sleep. The ship will right itself.”
The study also found that exercising for at least half an hour daily, doing more full-body cardio exercises such as swimming and boxing, and working out more in the morning, are some of the key factors that contribute to high-quality sleep at night. Those who incorporate weight lifting in their workout plans find it easier to pull themselves out of bed every morning after waking up, the study said. People who prefer ball sports, planking and sit-ups report longer periods of slow-wave sleep, or deep sleep, it said.
