Eat light at night．
Desiring a midnight snack？If your stomach starts rumbling（发出咕噜声） before bed，try reaching for good-for-you foods that actually promote sleep，like walnuts，tart cherries，or Greek yogurt instad．（17）D Eating too much of anything within a few hours of going to bed could suppress（抑制） your body's ability to produce sleep-promoting melatonin（褪黑素）．
