Myths - and Facts - About Sleep
There are many common myths about sleep. We hear them frequently, and may even experience them far too often. Sometimes they can be characterized as "old wives tales," but there are other times the incorrect information can be serious and even dangerous.

Snoring on a frequent or regular basis has been directly associated with hypertension. Obesity and a large neck can contribute to sleep apnea . Sleep apnea can be treated; men and women who snore loudly, especially if pauses in the snoring are noted, should consult a physician.

Sleep experts say most adults need between seven and nine hours of sleep each night for optimum performance, health and safety.

The resulting sleep deprivation has been linked to health problems such as obesity and high blood pressure, negative mood and behavior, decreased productivity, and safety issues in the home, on the job, and on the road.
