睡觉要讲科学。科学睡眠会叫你休息充分,精神充足,工作、学习效率高。怎样才能做到科学睡眠呢?一、要按时睡觉。每天按时在9点钟之前睡觉。第二天早晨按时在6点钟到7点钟之间起床。不要“开夜车”很晚睡觉,也不要贪睡懒(lǎn)觉。要保持自己生物钟的准确,否则,会影响你的健康。 Sleep should talk about science. Scientific sleep will call you to rest, full of energy, work, study and high efficiency. How to do scientific sleep? First, we should sleep on time. Sleep at 9 o’clock on time every day. The next morning on time between 6 o’clock and 7 o’clock to get up. Do not “open night car” sleep late, do not sleep snooze. To maintain the accuracy of your biological clock, otherwise it will affect your health.
