三、Go to the Gym After Work

　　下班后去健身房

　　Sleep experts used to believe that an a.m. workout was a great way to wake up the body. But actually, the ideal time is right after work. Three to five hours after exercising, your temperature starts to drop. That tells your brain that it's time for sleep. If you work out in the morning, your brain gets that sleep signal midday and throws off your rhythm.

　　睡眠专家曾经坚信上午健身对唤醒身体机能很有好处。但实际上，最理想的健身时间是下班后。因为运动之后的3到5小时，你的体温开始下降，而这将提示你的大脑，是该睡觉的时候了。如果你早上运动的话，你的大脑会在大白天就接到睡眠信号，从而大大减缓你的节奏。
