No matter how many times you read about how you need at least eight hours of sleep each night, if you just can’t bring yourself to relax and are not tired, there’s no point in forcing yourself. The reality is: you’re much better off going to sleep when you are really tired. Also you should not take sleeping pills or such, or caffeine within six hours before going to bed.
Get up at the same time every morning, even after a bad night’s sleep. You will be tired and ready the next night.
Scary movies or books are only for certain people. Generally you should avoid them, they might interrupt with your sleep.
So it’s simple things like those, that could virtually in an instant improve the quality of your nightly sleep and make you overall more productive during the day. It works.
