Building in extra bed time may be the secret to a better body, reports Yahoo News.

Once you’ve hit your foam roller and refueled with the necessary nutrients, do athletes actually need to sleep more post-hard workout? “The simple answer is absolutely,” says W. Christopher Winter, M.D., and director of the Martha Jefferson Sleep Medicine Center in Charlottesville, Virginia.

For the most part, everyone needs about 7 hours of sleep in a 24-hour window.

But “if you’re active—either physically or mentally—your body creates more adenosine, a chemical that works to create sleepiness, and you’ll accrue more of a drive to sleep,” Winter says.
