5. Set consistent, healthy mealtimes.

Regular mealtimes, not just regular sleep times, help regulate our circadian rhythms. Eating a healthy breakfast and lunch on time -- rather than grabbing a doughnut and coffee in the morning or a late sandwich on the run -- also prevents energy deficits¹ during the day that will aggravate² your sleepiness. Plan to finish eating meals two to three hours before bedtime.

设定一个一致的，健康的饮食时间

不仅是有规律的睡眠时间，有规律的饮食时间也对调节我们的生理节奏有帮助。按时吃健康的早中餐——而不是早上随手拿点油炸圈饼，喝点咖啡或者跑着吃些三明治——这可以防止我们在白天能量不足，如果能量不足的话将使你白天更困乏。计划在就寝两三个小时之前吃晚餐。

6. Exercise.

Regular exercise (30 minutes a day on most days) offers multiple benefits for sleep. Exercise, especially aerobic³ exercise, generally makes it easier to fall asleep and sleep more soundly.Exercise also gives you more daytime energy and keeps your thinking sharp. And if you exercise outside in daylight, you get still more benefits. Sleep experts recommend 30 minutes of exposure to sunlight a day because daylight helps regulate our sleep patterns. Avoid exercising within three hours of bedtime.

做运动锻炼

有规律的体育锻炼（大多数的时间坚持每天30分钟）对睡眠有诸多益处。运动，特别是有氧运动通常会使入睡更容易并且让你睡得更香。运动同时也使你白天的时候精力更充足，思维更敏锐。并且如果你在户外的阳光下运动的话，你将得到更多的益处。睡眠专家建议每天30分钟的日照时间，因为阳光帮助你调节我们的睡眠模式。就寝前三个小时之内不要有体育运动。
