Yet Bessesen says this experiment does fit in with a larger body of research on the importance of sleep. In fact, the amount of sleep people get has been decreasing greatly, he says. A 2015 study found the number of Americans who sleep less than 6 hours at night increased by about 30 million between 1985 and 2012. Scullin and Bessesen offer some ways to avoid health problems caused by a lack of sleep.
