6 hours of sleep? It is not enough
The good news is, a few in May right: Researchers from the University of California at San Francisco has a family with a genetic mutation that causes the members to require only six hours of sleep per night. The bad news? The gene is vanishingly rare, people who have less than 3% of the population.
So, almost everyone who says he needs only six hours of sleep is kidding themselves. And the consequences of chronic lack of sleep are severe, says Clet Kushida, president of the American Academy of Sleep Medicine and director of the Stanford University Sleep Medicine Center. Sleep deprivation has been an increase in motor vehicle accidents, defects in the short term memory, concentration and attention. E ‘also depressed mood and a decrease in the ability to control the appetite.
The family – mother and daughter with the gene mutation – were by researchers at UCSF study of circadian rhythms, the waxing and decreasing biochemical cycles of sleep, appetite and activity. Neither woman required more than six hours-6 hours and a half hours of sleep per night, but both were well-rested, healthy and energetic.
“One of them is over 70, still travels internationally and is very active. Danze has three or four nights a week,” said Ying-Hui Fu, professor of neurology at UCSF.
If the two scientists have the DNA, they found a mutation in a gene called DEC2 the cell and circadian rhythm.
The mutation seems to cause people who are much smaller than the normal eight hours-8 hours and a half that most people need for the proper functioning of rest, according to the document, which now number in the journal Science. The research of Fu and his colleagues found that humans and mice, the mutation is more intense sleep, as determined by a slow wave electrical activity in the brain, so they need less of it.
But it was estimated that only about 3% of the population, this gene, indicating that most people who are usually less than eight hours of sleep per night are just building a great and dangerous, the debt of sleep.
Fu said his lab to investigate to see if we can simulate the effects of gene therapy compounds, but there is research only at the beginning. For now, the only real answer to real productivity to sleep as much as the body needs, he says.
