Get good sleep.
Sleep is crucial to achieving optimum health. It is the time when our bodies regenerate. If we don't sleep, we don't regenerate properly. Lack of sleep can cause many problems which may lead to chronic health issues.
Set a regular sleep schedule -- and stick to it. Relax before bed. Meditate. Pray. Practice connected breathing. Read. Take a soak in a warm sea salt bath. DVR your late night shows.
