Although there is no particular diet that has been proven to be best for sleep, some sources suggest that eating a variety of whole foods and having a low glycemic diet should be evaluated in improving sleep. Low glycemic foods are ones that take a long time for your body to digest and absorb, like kidney beans, vegetables and avocados. One study found that people who eat diets high in sugar and refined carbs can take longer to fall asleep and wake more frequently during the night. Eating unhealthy fats can also disturb the body’s normal sleep-wake cycle. Last but not least, it’s best to avoid spicy and acidic foods that can cause heartburn, which can affect your sleep. Regular exercise and movement are very important for sleep as well. It’s important to move throughout the day, even if it’s just a short walk around your office, house or neighborhood.
