How bad habits affect your sleep?

影响睡眠的坏习惯

You drink too much alcohol

无节制酗酒

Ever woken up in the night after having one too many tipples? Well, science says this is down to alcohol-induced sleep disruption.

是否曾因多喝了一杯烈酒而半夜醒来?科学家说这是由酒精诱发的睡眠中断。

Drinking too much booze affects yoursleep pattern and quality as well as daytime alertness. In fact, one study hasidentified that alcohol, while improving the time it takes to fall asleep actually interrupts REM sleep later in the night.

过度酗酒不仅影响睡眠模式和质量，还会影响白天的警觉性。实际上，已有研究证实酒精在延长入睡时间的同时，还会打断夜里的REM睡眠(即快速眼动睡眠，在此睡眠阶段，眼球会快速移动，大脑神经元的活动与清醒的时候相同)。

The obvious solution here is to drinkless but if you are going to have a couple of glasses of wine give your body afew hours to process the alcohol before hitting the hay.

显而易见，要睡得好就得少喝酒。但如果你要小酌几杯，记得在睡前留出几个小时让身体消耗体内的酒精。
