Finding ways to get more and better sleep can be 'a challenge. Scientists have identified more than 80 different sleep disorders. Some sleeping disorders are genetic. But many problems are caused by staying up late and sleeping in, by traveling frequently between time zones or by working nights. Dr. James F. Jones at National Jewish Medical and Research Center in Denver says that sleep disorders are often diagnosed as other discomforts. About one third of the patients referred to with possible chronic fatigue syndrome actually sleep disorders. "Before we do anything else, we look at their sleep," Jones says.
Sleep experts say that most people would benefit from a good look at their sleep patterns. "My motto is' sleep defensively', says Mary Carskadon of Brow University. She says people need to carve out sufficient time to sleep, even if it means giving up other things. Sleep continues-like going to bed and getting up at the same time every day -- are important.
