Sleep is crucial for good mental and physical health — and what you eat can affect how well you rest. Certain foods have vitamins and minerals that increase your body’s sleep-promoting hormones, serotonin (the calming hormone) and melatonin (the drowsiness hormone), which aid in getting a restful night’s sleep. If you’re one of the 70 million Americans who suffers from chronic sleep problems, try adding one (or all!) of these sleep-inducing foods to your diet.
