Researchers had 14 healthy young adults stay up all night and all the next day and then compared their reactions with 13 subjects who had slept normally. ![]() Oddly enough, it can also bring on temporary euphoria, according to a study in the journal Neuroscience last month.

Those who make the initial screening wear monitors to track their sleep patterns at home.Ī University of Utah neurologist and sleep scientist who oversees the recruiting, says there is one question that is more revealing than anything else: When people do have a chance to sleep longer, on weekends or vacation, do they still sleep only five or six hours a night? People who sleep more when they can are not true short sleepers, he says. Potential candidates for the gene study are sent multiple questionnaires and undergo a long structured phone interview. The researchers are recruiting more candidates and hope to find more gene variations they have in common. News of their finding spurred other people to write the team, saying they were natural short sleepers and volunteering to be studied. The scientists were able to replicate the gene variation in a strain of mice and found that the mice needed less sleep than usual, too. Genetic analyses spotted one gene variation common to them both. They were studying extreme early birds when they noticed that two of their subjects, a mother and daughter, got up naturally about 4 a.m. Fu was part of a research team that discovered a gene variation, hDEC2, in a pair of short sleepers in 2009. "Everybody can use more waking hours, even if you just watch movies."ĭr. "My long-term goal is to someday learn enough so we can manipulate the sleep pathways without damaging our health," says human geneticistĪt the University of California-San Francisco.

There is currently no way people can teach themselves to be short sleepers. The natural short sleepers scored twice as high as the controls. He was one of the authors of a 2001 study that had 12 confirmed short sleepers and 12 control subjects keep diaries and complete numerous questionnaires about their work, sleep and living habits.One survey dubbed "Attitude for Life" that was actually a test for hypomania. They're always on the up side of life," says Dr. They rarely go to sleep clinics and don't think they have a disorder.Ī few studies have suggested that some short sleepers may have hypomania, a mild form of mania with racing thoughts and few inhibitions. To date, only a handful of small studies have looked at short sleepers-in part because they're hard to find. adults who get less than the recommended seven hours of sleep per night, according to a report last month by the Centers for Disease Control and Prevention. The rest end up chronically sleep deprived, part of the one-third of U.S. ![]() Out of every 100 people who believe they only need five or six hours of sleep a night, only about five people really do, Dr.
