• Sleep only when sleepy. If you can't sleep, get up and do something boring.
• Develop sleep rituals to let your body know it's time to unwind and relax.
• Take a hot bath 90 minutes before bedtime
• Use sunlight in the morning to set or reset your biological clock.

Sleep deprivation is no laughing matter. As well as disturbing your thinking patterns, it weakens your body, making it more susceptible to disease. It reduces your reaction time so you cannot react to danger as quickly. You may also fall asleep at inopportune times, like while you are operating a vehicle. Many accidents are caused by drowsy drivers. Another hazard is fire from a smoldering cigarette or a skillet left on a hot burner.

Do yourself and the world a favor. Get the sleep you need.
