Natural short sleeper
Alternative namesSleep - natural short sleeper
DefinitionA natural short sleeper is an individual who habitually and spontaneously sleeps substantially less in a 24-hour period than is expected for a person in his or her age group, and does not have excessive sleepiness.
Signs and tests
Although there is a broad range of variation in the individual need for sleep, the typical adult requires an average of 7 to 10 hours each night. Short sleepers have a daily total sleep time of less than 75% of the age-related norm, and awaken spontaneously.
They should be differentiated from people who chronically obtain inadequate sleep because of work or family demands, or who have medical conditions that disrupt sleep.
Natural short sleepers are not excessively tired or sleepy during the day. If you are a "natural short sleeper," who functions effectively during the day, there is no need to consult a physician.
