For people that do not get the full 8 hours of sleep each night, it might be okay because you can catch up on those nights over the weekend. A new study found that two days of extra sleep can reverse the metabolic damage from sleep deprivation.
“You are going to improve your insulin sensitivity and giving yourself permission to sleep in … prevents your future diabetes risk,” said Josiane Broussard, assistant research professor at the University of Colorado, Boulder, an author of the study.
A study by Broussard and Dr. Esra Tasali, an associate professor of medicine at the University of Chicago, had 19 healthy men participate in two sleep studies. Phase one, the men stayed in bed for 8.5 house for four days. Phase two, they were in bed for 4.5 house for four days and made up the sleep in “recover days” over the weekend.
On the first recovery day, they stayed in bed for 12 hours and could sleep as much as they wanted; on the second they stayed in bed for 10 hours and could sleep as much as they wanted.
Broussard and Tasali tested the subjects blood sugar every day.
When the men were sleep deprived their insulin sensitivity or ability to regulate blood sugar decreased by 23 percent. This increased their diabetes risk by 16 percent, but once they had two days of make-up sleep and averaged about 9.5 hours, their levels returned to normal.
“The body is adaptive,” Tasali said. “If you were to catch up on sleep, a good amount of sleep, an average of 10 hours of sleep, you can go back to baseline and reduce your risk.”
“This was a short-term study and often people are chronically sleep deprived,” said the sleep medicine doctor at the Center for Sleep Disorders in the Neurological Institute at Cleveland Clinic. “We still don’t know whether the chronic effects [of sleep deprivation] can be reversed with extra sleep on the weekend.”
“You cannot infer what could be happening with the female population,” said the assistant professor of clinical medicine at Keck School of Medicine at the University of Southern California and a fellow of the American Academy of Sleep Medicine.
The study was not tested on overweight people or a large population to see if this works for the masses.
Well we say more sleep is great!!! Keep on, sleeping on.
