一個老生常談： 睡前別再玩手機了！ 誰知道睡前的手機咋那么好玩！
In the evening, our bodies make melatonin (褪黑素). Melatonin makes us feel sleepy and relaxed. It’s an important part of our sleep cycle. Electronic screens prevent that cycle from working in a normal way. 晚上，隨著人體褪黑素分泌的增多，人們會覺得困意重重。褪黑素對于改善睡眠很重要！而電子屏幕的藍光卻會抑制褪黑素的分泌——這還叫人咋好好睡覺？
Phones, computers and TVs produce blue light which stops our bodies from making melatonin. Even just a little bit of blue light can have a big effect. Eight minutes of blue light can keep your brain “awake” for another hour, according to the study. Even if you fall asleep, you may have lots of dreams. This means you’re not having a good rest. 研究表明，8分鐘的藍光足以讓你的大腦再“清醒”一個小時！即便是睡著了，也可能多夢影響睡眠質量。
It’s even worse if you play exciting games before bed.Games make our hearts beat faster, so we have a harder time falling asleep. Then, when we do fall asleep, we don’t get enough “deep sleep” – the crucial part of sleep that leaves us feeling well rested. 你還喜歡在睡前玩游戲？那你可能更睡不好！游戲會讓我們心跳加快，更難入睡，“成功睡著”后還會影響深度睡眠時間——所以有人一覺醒來卻依然感覺沒休息好，仿佛睡了個假覺……
