9. Insomnia - the inability to fall asleep or to stay asleep - is a condition that plagues many people at one time or another in their lives. It can be uncomfortable, but is usually not harmful, and most people who believe they have been awake all night have actually slept more than they think. While some people rely on prescription medication to help them sleep, insomnia can be controlled by changing behavior. Insomnia is often caused by stress or anxiety, but it can also be made worse by eating too heavily too late; consuming a lot of caffeine; or watching television, using computers, or exercising right before bedtime. If you can't sleep, the best thing to do is to get out of bed and do something calming for a while, such as read, until you feel sleepy. Some people find that herbal tea such as chamomile helps them feel drowsy.
