Maybe you pride yourselves on only sleeping a few hours a night. However, are you feeling tired and sleepy throughout the day? Do you have a hard time keeping your eyes open as you study? Have you nodded off while driving? If you can answer "Yes" to any of these, it shows you could not have enough sleep.
It is suggested that most adults need seven to nine hours' sleep. As for teens, they need even more. If you aren't getting enough sleep, you should：
● Avoid Caffeine(咖啡因)
You should avoid drinking caffeinated drinks such as coffee, tea and soda for at least 10 hours before you go to bed.
● Avoid eating big meals before sleeping
Eating a big meal can make you feel sleepy, and it can make you feel uncomfortable and prevent you from sleeping well.
● Build a healthy sleep environment
With the light on, can you have a good sleep? Of course not, and you'd better keep your bedroom dark and cool.
● Avoid using electronics before bed
The light from electronics can keep you from falling asleep. Try reading or listening to quiet music instead.
Please get enough sleep from now on.
