Use weekends to catch up on sleep

Growing up you were considered lazy for sleeping in on the weekends, butresearchfrom the University of Chicago considers it a sound health investment. In the study, participants who wereallowed to have two consecutive nights of extended sleep (an average of 9.7 hours a night) after four consecutive days of sleep deprivation (4.5 hours a night) exhibited a reduced risk of diabetes.After the four night sleep restriction, the volunteers insulin sensitivity decreased by 23 percent and their diabetes risk increased by 16 percent. But the two nights of extended sleep restored their insulin sensitivity and risk of diabetes to normal sleep levels, effectively reversing the negative metabolic effect of too little sleep.
