Even though sleep is pretty much the opposite of physical exertion, exercise conducted at the right time of day (i.e., not too close to bedtime) is one of the best things you can do to get a good night’s rest. Exercise helps regulate the body’s natural circadian rhythm, which promotes sleep. According to the National Sleep Foundation, exercise can also improve insomnia by lowering symptoms of anxiety and depression, two conditions linked to sleep disruption. Daily physical activity also helps reduce cortisol, the body’s primary stress hormone.
Certain protein-rich foods like milk, eggs, peanuts, and soy contain an amino acid called tryptophan that causes sleepiness, says Alissa Rumsey, MS, RD, founder of Alissa Rumsey Nutrition and Wellness. For best results, combine these foods with a source of carbohydrates, which help more tryptophan enter the brain. Some recommendations: roasted soybeans, peanuts, sunflower seeds, cheddar cheese, canned tuna, and pistachios. You don't need much: "Even smaller snacks can provide a tryptophan dose that studies have shown to be significant in helping with sleep," Rumsey says.
Give yourself some dedicated wind-down time. It doesn’t have to be a full hour or an elaborate routine, but try to spend at least 20 to 30 minutes doing something that relaxes you before you try to fall asleep. That could be taking a warm bath or shower, changing into comfy pajamas and sipping a cup of chamomile tea. Or something completely different — so long as it’s relaxing to you.
