Sleep is very important for healthy life. We may often think we get enough sleep but still feel tired. Most people will say that's because you don't have enough exercise. If you don't have healthy sleeping habits, you may not work or study well. This is why a nine-hour night of sleep is necessary. If you have no idea about how to build a healthy life, these are some habits you need to avoid (避免):
Phones are in the bedroom.
The blue light from your phone screen, for example, can confuse brain (迷惑大脑) into thinking it's daytime. A room with light on will make you want to work or do other things.
Put your phone next to your head while sleeping.
Do you use your phone as an alarm to wake you up in the morning? It's not a good idea to use your phone to start your day. You'll check your email and get into a bad mood (心情) when your alarm rings.
An untidy environment (环境).
