This hormone tells your body when to sleep and wake. Some research suggests that melatonin supplements can ease sleep issues like jet lag and trouble falling or staying asleep. For the most part, melatonin is safe for healthy adults if taken for only a few weeks or months. Side effects include headache, dizziness, and nausea. Try taking 1-3 milligrams 2 hours before bed.
Try sniffing this purple flower before your bedtime. Its scent slows your heart rate and lowers your blood pressure and skin temperature. This can set the stage for slumber. A study found that people who snoozed in a lavender-infused room had more restful deep sleep than those who didn’t. Want to try it? Run an essential oil diffuser in your bedroom, or add a few drops to your pillowcase.
