Having enough sleep can make the difference between a great day and a terrible one! Here are the tips for a good night's sleep: First， go to bed and get up at the same time， even if you haven't gotten a good night's sleep. Sleeping late for just a few days can change your body clock to a different cycle. Also， avoid big meals at night. Eating heavy rich food within two hours of bedtime can keep you awake， Your stomach works hard because of those fatty foods， and that may keep you up. Your body produces a chemical called melatonin that helps you sleep. Light changes the amount of melatonin. It produces more in the evening and less in the daytime. So at night turn off your TV and PC. Also， don't read from abacklit device(有背光的设备) like an iPad. Some scientists think that the light from those devices stops your body from making melatonin.
