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

谷類

在睡前吃一小碗谷類食品你不必心虛，尤其是低糖的、整谷谷類食品。它不僅是健康點心（確保上面加上牛奶，以供給身體必需的蛋白質），而且可以幫助睡眠。“復合的富含碳水化合物的食品會增加血流里的色氦酸，增加誘導睡眠效果”，史密斯博士說。另外的好處：在你的碗里加上幾粒干櫻桃（見以上），可以格外幫助你呼呼入睡。
