Diet can also play a role in promoting better sleep. Foods rich in tryptophan, such as turkey, nuts, and seeds, can help to increase the production of serotonin in the day and melatonin at night—a hormone that promotes sleep. Magnesium-rich foods like leafy greens and bananas can also help relax the body and prepare it for sleep. Additionally, consuming foods that contain natural melatonin, like cherries, can help to regulate the sleep–wake cycle.While some soothing foods will help to calm us down, the key is to have a diet that generally includes foods such as those listed above. If you eat a mouthful of one of these foods just before going to bed, don’t expect to see any difference. Rather, integrate them into your diet, and consider them part of a healthy relationship with sleep. They will not work like a sleeping pill, so don’t be fooled!
