Dr. Cherry,
Do you recommend using sunglasses when out in the sun? I heard one person say that the body absorbs more "nutrients" from the sun without sunglasses that with sunglasses on. What is your opinion?
Thanks!
You should always wear sunglasses when in the sun. Unprotected exposure to the sun's ultraviolet (UV) rays can increase the risk of developing cataracts and macular degeneration, and can also cause damage to the retina. UV damage is cumulative, so the longer your eyes are exposed to UV radiation, the greater the risk of developing these conditions.
The nutrient your body makes from the sun is vitamin D, and that process takes place through exposure to unprotected skin (but to protect your skin from sun damage, keep it short - 10-15 minutes on the arms or legs only).
