Here are a few tips: Eat a banana because it contains melatonin (sleep hormone). Drink a mug of warm milk, as the tryptophan content of dairy products promotes melatonin production. Don't drink too much coffee in the afternoon, and don't eat too late. We can use lavender because the smell of lavender slows our heart rate and lowers our blood pressure, and we can relax from it more easily. Choose a suitable mattress for sleeping. It is worth training your body so that we can relieve the accumulated stress.
