人的一生中超过三分之一的时间是在睡眠中度过的。高质量的睡眠是健康和更好地学习、工作的保证。然而，你是不是也有过失眠的经历?或者睡了一觉醒来还是觉得昏昏沉沉?其实，睡眠其实也是一门学问，掌握一些小窍门，你会睡得更香甜。
No one likes to toss and turn all night, or even worse, struggle with outright insomnia.
There are things you can do to help get a better night’s rest. Try any or all of the following relaxing behaviors just before bedtime to ensure a more restful night.
Shun p.m. stimulants
Skipping your normal cup of joe should help you fall asleep quicker, because caffeine is a stimulant. “I don’t like people having caffeine after noontime if they have poor sleep, because it can hang out in the system for a long time,” says Walsleben.
Even decaf drinkers should beware: A recent Consumer Reports study found that even decaffeinatedcoffees sold at several chain restaurants contained caffeine, with one from a big chain having 32milligrams of caffeine per cup—about the same amount as in 12 ounces of cola.
Nicotine is also a stimulant; smoking to relax before bed can actually do the opposite, revving up your heart rate and keeping your brain alert, says Walsleben.
Limit evening food and drinks
A large meal or spicy snack too close to bedtime can leave your digestive system working overtime while the rest of your body lies awake. And alcohol may make you drowsy, but it will disrupt your sleep patterns later in the night and keep you from getting the deep, which you need to feel refreshed.
If you drink a lot of any liquid before bed, for that matter, you may be up throughout the night using the bathroom.
Take a hot bath
Your temperature naturally dips at night, starting two hours before sleep and bottoming out at 4 a.m. or 5 a.m., according to a study conducted by New York Hospital-Cornell Medical Center in White Plains, N.Y. When you soak in a hot tub, your temperature rises—and the rapid cool-down period immediately afterward relaxes you.
Two hours before bed, soak in the tub for 20 or 30 minutes, recommends Joyce Walsleben, PhD, associate professor at New York University School of Medicine. “If you raise your temperature a degree or two with a bath, the steeper drop at bedtime is more likely to put you in a deep sleep,” she says. A shower is less effective but can work, as well.
Lay out your clothes
You can help your body recognize that bedtime is imminent by setting routines and repeating them every night.
“We suggest that people establish regular nightly routines before they get into bed, to help their brain shift into sleep mode,” says Gary Zammit, PhD, director of the Sleep Disorders Institute in New York. “Laying out your pajamas, brushing your hair and your teeth—these habits can be very sleep-conducive.”
Install a dimmer switch
Late in the evening, your body releases the chemical melatonin, which makes you sleepy—but only if it receives the right cues from your environment. “Melatonin is your hormone of darkness—it won’t flow with the lights on,” says Walsleben. Sitting in a dimly lit room before getting ready for bed can put you in the right mind-set for sleep.
Shut down electronics
You may find it relaxing to catch up on correspondence with friends just before turning in for the night, but the practice could increase the amount of time you toss and turn. Lit screens (that includes televisions too) are stimulating, says Walsleben, so it’s best to avoid them. “Before your targeted bedtime, begin slowing down your brain by doing something calming, like reading in a comfy chair—somewhere other than bed,” she says. “Stop watching TV and checking email.”
Wear socks to bed
If cold feet are keeping you awake—especially during the winter—warm them up with a soft pair of socks. The extra layer under the covers can help improve circulation in your extremities, which can help you fall asleep more quickly.
