By the age of 80, cerebral blood flow is approximately 20% less than at age 30, which means that the heart has less capacity for physical exertion and may feel fatigued more easily. As a result, we feel a gradual decline in our energy and endurance levels.
We grow up and we don't look quite the same. But all this is only on the outside. Beneath the surface, your body is aging too, and sleep loss can speed up the process.

Skin makes new collagen when you sleep, which prevents sagging. “That's part of the repair process,” says Patricia Wexler, MD, a dermatologist in New York. More collagen means skin is plumper and less likely to wrinkle. Only getting 5 hours a night can lead to twice as many fine lines as sleeping 7 would.
