Traditional uses of goji berry are used to induce sleep and to reduce stress. Research has shown that goji berries, when given to human subjects, improved their quality of sleep significantly without having any adverse effects. In the study, easy awakening was also observed compared to the control group.
Walnuts are also great sleep aid. Melatonin, a hormone that helps induce and regulate sleep, is naturally in walnuts. Thus, walnuts make for a perfect snack after dinner that will help you to a great, restful night of sleep.
