There is a reason it is called "beauty rest." Sleep deprivation gives you dark circles and dull skin. It can also cause weight gain, diminished immune response and foul moods. The key to sleeping more is simple: Go to bed earlier. Here's how:
Establish a new bedtime: Go to bed 15 minutes earlier each night for four nights in a row, and get 20 minutes of bright light every morning to help regulate the hormones that will make you tired in the evening (either outdoors or from a light box). Then stick to your new bedtime and wakeup call.
Go dark: Exposure to light, even at the level in most living rooms, can suppress the release of melatonin, the sleep hormone, making it difficult to doze off. An hour before bedtime, dim the lights, turn off the TV and computer and make your room as dark as possible.
Release tension: Consider taking a warm bath an hour before bed. Beyond feeling relaxing, the rise and subsequent fall in body temperature slows the heart and makes you drowsy.
