Is It Possible to Get Too Much Sleep

By Jana Kaplan You're groggy, dizzy even. You can't see straight and you sure as hell can't keep your eyes (or your mind) focused on the screen in front of you. And you're pretty sure your boss has noticed. You want to assure her that you're not drunk and you got enough sleep. In fact, you got more than enough. Could that be the problem? The Rumor: Sleeping too much is just as bad as not sleeping enough We've all heard how important it is to get enough rest, even though most of us don't...

False: More and more scientific studies are showing correlations between poor quality sleep and/or insufficient sleep with a variety of diseases, including high blood pressure, diabetes, and depression. For example, insufficient sleep can impair the body's ability to use insulin, which can lead to the development of more severe diabetes. Patients with poorly controlled diabetes and sleep apnea have improvement of blood sugar control when treated for sleep apnea. This is also found in patients with high blood pressure and sleep apnea. When the sleep apnea is treated, the blood pressure also improves. In addition, too little sleep may decrease growth hormone secretion, which has been linked to obesity.

Older people need less sleep.

False: The average adult needs a total sleep time of seven to nine hours per day. While sleep patterns usually change as we age, the amount of sleep we generally need does not. Older people may sleep less at night due, in part, to frequent night waking, but their need for sleep is no less than that of younger adults.

Snoring can be harmful.

True: Aside from bothering other people, snoring is not harmful. However, it can be a sign of sleep apnea, a sleep disorder that is associated with significant medical problems such as cardiovascular disease and diabetes. Sleep apnea is characterized by episodes of reduced or no airflow throughout the night. People with sleep apnea may remember waking up frequently during the night gasping for breath.

You can "cheat" on the amount of sleep you get.

False: Sleep experts say that most adults need between seven and nine hours of sleep each night for optimal health. Getting fewer hours of sleep will eventually need to be replenished with additional sleep in the next few nights. Our body does not seem to get used to less sleep than it needs.

Teens need more sleep than adults.
