Surfing the Web before bed may seem like a relaxing, low-key activity. But it could rob you of something very important (hint: it's not your identity).

We're talking about sleep. In a group of people who reported spending up to 2 1/2 hours a night browsing sites on the Internet, over one-third of them also had some kind of problem with their sleep. Here are some better bedtime rituals.

Sounder Sleep
It appears that high-excitement media inhibits drowsiness (watching late-night TV made sleep time less productive, too, in a recent study). The light your body is exposed to via TV screens and computer monitors seems to mess up your natural sleep/wake cycles and rhythms.

Here are better ways to ease your body into sleep mode.

• Love your routine. A consistent bedtime helps you sleep better.
• Do some gentle stretches every morning. Here's why this helps.
• Put on a pair of warm socks. This is what it will do for you.
