With these tips you can finally get a solid night's sleep.
Reserve Your Bed
Get into bed just for sleeping. Avoid working, paying bills, reading, or watching television in bed. If you associate your bed only with sleep, you’ll be more likely to fall asleep.
Watch the Caffeine(咖啡因)
Too much caffeine throughout the day can cause interrupted sleep. Limit yourself to two cups of tea, coffee, or cola, taken at least 6 hours before bedtime.
Tap the Exercise Answer
In a study from Stanford University School of Medicine, a group of 50- to 76-year-olds who had complained of sleep problems began proper exercise for about half an hour four times a week. Compared with a similar group of people who didn’t exercise, the more active group slept an average of one hour more each night, took less time to fall asleep.
Take a Bath
Take a warm bath an hour or two before bed. Your body temperature will slowly drop after you get out of the tub（浴盆）, making you feel tired. Don’t bathe right before bed, however, because it can briefly stimulate you enough to make it hard to fall asleep.
Buy the Right Bed
A bed that’s too soft can cause poor sleep. Replace your mattress(床垫)if it’s more than ten years old, and buy one that’s as firm as you can tolerate but still comfortable.
If 30 minutes go by and you haven’t fallen asleep, don’t lie in bed feeling frustrated. Get up and do something relaxing.
