Tanning
Tanning outside or indoors can have dangerous consequences. While often associated with good health, the “glow” of a tan is the very opposite of healthy; it’s evidence of DNA injury to your skin. Tanning damages your skin cells and speeds up visible signs of aging. Worst of all, tanning can lead to skin cancer.

There is no such thing as a safe or healthy tan. Tanning increases your risk of basal cell carcinoma, squamous cell carcinoma and melanoma. Your best defense is to avoid tanning altogether.
