One of the most important factors in good health is sleep. Get 7-8 hours of uninterrupted sleep every night. Get to bed by 10 pm. Stop using electronics as early as possible early in the evening. Go to bed at the same time each night. Stop ingesting fluids at least a couple hours before going to bed. If you have to get up during the night to use the bathroom do not turn on a light as this will stop melatonin production making it more difficult to fall asleep again.
