Cereal

There’s no need to feel guilty about having a small bowl of cereal before bed, especially if it’s a low-sugar, whole-grain cereal. Not only is it a healthy snack (make sure you top it with milk to give your body the protein it needs), but it may also help you snooze. “Complex carbohydrate–rich foods increase the availability of tryptophan in the bloodstream, increasing the sleep-inducing effects,” says Dr. Dalton-Smith. Bonus: Top your bowl with a sprinkling of dried cherries (see above) for extra help catching your zzz's. Photo: Thinkstock

谷类

在睡前吃一小碗谷类食品你不必心虚，尤其是低糖的、整谷谷类食品。它不仅是健康点心（确保上面加上牛奶，以供给身体必需的蛋白质），而且可以帮助睡眠。“复合的富含碳水化合物的食品会增加血流里的色氦酸，增加诱导睡眠效果”，史密斯博士说。另外的好处：在你的碗里加上几粒干樱桃（见以上），可以格外帮助你呼呼入睡。
