The answer is Yes!
New research has found that wearing sunscreen—continuously–can reduce the amount of vitamin D a person is able to make. Sunscreens limit the Vitamin D the body produces by blocking ultraviolet rays from the sun.
At least some sunlight is the key to staying healthy.
“I believe that Americans have gone overboard with their fear of the sun. I think that sensible exposure to sunlight is really important for your overall health and well-being,” says Dr. Michael Holick, Professor of Medicine, Physiology and Biophysics at Boston University School of Medicine.
“We looked at individuals that always wore a sunscreen before they went outside. And we found that, indeed at the end of the summer, they were deficient in vitamin D,” says Holick.
“…so we have shown over and over again that adults, even if they’re on a multivitamin, and drinking milk, if they always wear sun protection, or avoid any direct sun exposure, they’re at high risk of developing vitamin D deficiency“.
The most effective way to obtain this vital nutrient is to get your vitamin D from the sun. But how much sun does it take for vitamin D to be optimized?
Experts recommend exposing uncovered arms and legs to bright, mid-day sun between the hours of 10:00 am and 4:00 pm.
Exposure of 25% or more of the body’s total skin surface is necessary, but take care in protecting very sensitive areas like the face.
The amount of time needed can be gauged by Vitamin D UV Activation Sensors available from SkinHealth Technology. The sensors are the size of a postage stamp and are easy and convenient to use. Simply apply one to skin or clothing and when the color changes from yellow to red—vitamin D optimization is complete.
