But, when you’re not, it can last far into the day, with unpleasant and even risky results….The result is a kind of constant jet lag—and one that is exacerbated by sleeping in on the weekends.

After 15,000 responses rolled in for the collaborative survey, we did the math and found out that more than 95 percent of responses wish they got more sleep -- and more than a third of them are logging five hours or less each night….The good news? The survey also revealed that almost every single participant said that they are somewhat or very willing to make lifestyle changes that would benefit their sleep quantity and quality in the long run.”
