Adding 17 minutes of sleep seems to be very few, but in fact it may be a lot, which varies from person to person. For those who sleep deeply and calmly, sleeping 65,438+07 minutes a day doesn't seem to change anything, but for those who have difficulty falling asleep or wake up many times in the morning, sleeping a little more every night may be very beneficial.
For the latter, they must be interested in the details of a recent study. According to this study, lifting weights or doing push-ups can provide 17 minutes of extra sleep. For people with sleep problems, this kind of exercise seems to be better than jogging or cycling.
This study studied 386 overweight or obese people, aged between 35 and 70, who lived a sedentary life and had relatively high blood pressure.
In order to facilitate the analysis, the participants were divided into four groups: one group did not exercise, the other group spent three hours a week on strength training on fitness equipment, the third group did aerobic exercise for three hours a week, ran on the treadmill or stepped on the elliptical machine, and the last group did the above two kinds of exercise every week. All participants were asked to report the sleep quality, sleep time and how long they actually stayed in bed.
The researchers observed that among those who slept less than 7 hours a night, those who ran, rode bicycles or stepped on elliptical machines slept an average of 23 minutes more every night. Those who do strength training have an extra 40 minutes of sleep. At the same time, people in aerobic exercise group and comprehensive exercise group spend more time in bed, and people in strength training group fall asleep faster. The sleep quality and sleep disorder of all exercise groups have improved.
Angelique Brerentin, a scientist at Iowa State University, pointed out that aerobic exercise and strength training are both important for human health. The results of this study further show that strength training may be better in improving the quality of sleep at night.
