9. Move your bed away from any outside walls. This will help cut down on noise, which a Spanish study found could be a significant factor in insomnia. If the noise is still bothering you, try a white noise machine, or just turn on a floor fan.
9.把你的床从外墙那边移开。来自西班牙的一项研究表明噪音是导致失眠的重要因素，与外墙隔开便能远离外部噪音。要是还不行，试试使用白色噪音机（能发出诸如海浪声、雨声之类有助睡眠的声音），或者直接开一个落地风扇。

10. Tuck a hot-water bottle between your feet or wear a pair of ski socks to bed. The science is a little complicated, but warm feet help your body's internal temperature get to the optimal level for sleep. Essentially, you sleep best when your core temperature drops. By warming your feet, you make sure blood flows well through your legs, allowing your trunk to cool.
10.在两脚间塞一个装热水的瓶子，或者穿双滑雪短袜。其中的科学原理有些复杂，不过暖脚能帮助身体内部体温达到适合睡眠的最佳温度。基本上，当你身体中心温度下降的时候你睡得最香。通过脚的加温，腿部血液流动加快，躯体的温度就会下降。
