How to Sleep Better
If you’re having trouble getting good sleep through the night (turning，waking up more than once，for example)，this text will tell you what you can do to ensure a peaceful night’s sleep.
1．Get on schedule.Changing your sleeping time by more than an hour can severely disturb your sleep quality.__1__For example，if you normally wake up at 6 am on weekdays to get to work，you might go to bed around 10 pm，because that’s when you start to feel sleepy，and it’s also a good time to ensure 8 hours of sleep.If，on the weekend，you sleep until 9 am，you probably won’t be able to fall asleep that night until 1 am.
