Planning for a good night’s rest can start with a sleep-friendly dinner, says clinical psychologist Michael Breus. A good main course is salmon because it offers a healthy dose of omega-3 fatty acids, which have been shown to reduce surges of stress hormones and promote restfulness, according to the UCLA Center for East-West Medicine. Not a fan of salmon? Other fish, such as halibut, also provide the benefits of omega-3. Plus, these fish contain vitamin B-6, which is needed to make the sleep-inducing hormone melatonin.
