A natural short sleeper is someone who sleeps a lot less in a 24-hour period than is expected for people of the same age, without being abnormally sleepy.
Although each person's need for sleep varies, the typical adult needs an average of 7 to 9 hours of sleep each night. Short sleepers sleep less than 75% of what is normal for their age.
Natural short sleepers are different from people who chronically do not get enough sleep because of work or family demands, or those who have medical conditions that disrupt sleep.
Natural short sleepers are not overly tired or sleepy during the day.
No specific treatment is needed.
