Sleep is often taken advantage of. It seems it is the first thing off the to-do list. The recommended amount of sleep for adults is 7.5 to 9 hours per night. Too often this does not occur. Minimal sleep loss can take a toll on your mood, energy level and ability to handle stress. Over time, sleep loss has been linked to other health consequences such as hypertension, diabetes, obesity, depression, heart attack, stroke, and at-risk behaviors.
