Getting Better Sleep

Zeitgebers are environmental cues that affect your circadian rhythm (process C). Meals and exercise are examples of zeitgebers, but the most powerful zeitgeber is light and dark. Light suppresses melatonin secretion and if you get too much light in the night, this can prevent you from falling asleep. Try to avoid room lights and electronic lights a few hours before bedtime. Use blue-spectrum light blocking glasses if you need to.
