Can lack of sleep really cause premature aging?

Chronic lack of sleep may contribute to premature skin ageing by interfering with the skin’s natural repair processes. Over time, it can affect collagen production, increase inflammation, and make fine lines, wrinkles, and dullness more visible.

• How many hours of sleep do I need for healthy skin?
  Most health experts recommend that adults get 7-9 hours of quality sleep every night. Adequate and consistent sleep gives the body and skin enough time to carry out important repair and recovery processes.
• Can poor sleep cause dark circles and puffy eyes?
  Yes, inadequate sleep may lead to fluid retention and make the blood vessels under the eyes more visible, contributing to puffiness and a dark appearance around the eyes.
