Do you play with your phone before bedtime? You may want to read a book instead. According to a US study,looking at screens(屏幕) at night can cause us to sleep poorly.
In the evening,our bodies make melatonin(褪黑素). Melatonin helps us feel sleepy and relaxed. It's an important part of our sleep cycle(周期). Our electronic screens stop that cycle from working normally(正常地).
Why? Phones,computers and TVs make blue light. Blue light stops our bodies from making melatonin. Even just a little bit of blue light can have an effect(影响). Eight minutes of blue light can keep your brain(大脑) "awake" for another hour,according to the study. Even if you fall asleep,you may have lots of dreams. Your brain won't have a good rest.
It's even worse if you play an exciting game before bed. Games make our hearts beat faster,so we have a harder time falling asleep. Then,when we fall asleep,we don't get enough "deep sleep".
