Researchers claim nearly one billion people worldwide may be having deficient or insufficient levels of vitamin D due to inadequate sun exposure related to sunscreen use.

Sunscreens are known to protect skin against sun damage. However, a new research suggests otherwise – regular use of suncreen could cause vitamin D deficiency, leading to muscle weakness and bone fractures.

Researchers claim nearly one billion people worldwide may be having deficient or insufficient levels of Vitamin D due to inadequate sun exposure related to sunscreen use.

“People are spending less time outside and, when they do go out, they’re typically wearing sunscreen, which essentially nullifies the body’s ability to produce Vitamin D,” said Kim Pfotenhauer, Assistant Professor at Touro University in California.

“While we want people to protect themselves against skin cancer, there are healthy, moderate levels of unprotected sun exposure that can be very helpful in boosting Vitamin D,” Pfotenhauer said.

The study also showed that chronic illnesses like Type 2 Diabetes and those related to malabsorption, including kidney disease, Crohn’s and celiac disease may lead to malabsopbtion of the vitamin, although poor diet can also make you deficient.

Considered a hormone rather than a vitamin, Vitamin D is produced when skin is exposed to sunlight. Vitamin D plays a wide role in the body’s functions, including cell growth modulation, neuromuscular and immune function and inflammation reduction.

Spending as much as five-30 minutes in midday sun twice per week may help increase and maintain healthy Vitamin D levels. However, it is important to forgo sunscreen during these sessions because SPF 15 or greater decreases vitamin D3 production by 99 percent, the researchers said.
