How much sleep is enough? Is how sleepy you feel a good judge of whether or not you are getting enough sleep? If you get less sleep than some ideal amount but you feel fine, could you be damaging your health anyway? As it turns out, a restless night doesn’t just leave you sluggish. Not getting enough sleep can have devastating effects on your heart, your weight, and your brain.
