How do hypnotics work?
They work on your brain by reducing the level of mental activity, allowing you to fall asleep more easily. Unfortunately, the nature of your sleep is affected. The amount of dream sleep and deep sleep is reduced. Light sleep is increased. Therefore, even if you sleep for longer, you might not feel as well rested as you do after a night of natural sleep. Zopiclone and zolpidem are designed to help your sleep follow a more natural pattern.
