Dr. Michael Breus answered:
Here are a few good facts that people should bear in mind:
• As we age, lack of sleep affects us more deeply and shows up more
prominently on our faces (which explains why dark circles, fine lines,
and pallid complexions aren’t a problem in our twenties despite the
late nights, but can be later on).
• Sleep induces the production of collagen, a key ingredient in firm,
youthful skin.
• The skin’s capacity to hold water is enhanced by sleep, thereby
keeping skin moisturized and supple.
• Sleep deprivation can sting the immune system, leaving one
vulnerable to rashes and skin-related problems.
• Growth hormone peaks during deep sleep, and this hormone plays a
central role in initiating cellular repair.
