Sunscreen Protects Against Skin Cancer, But Also Carries Some Dangers

Sunscreen is essential to protect the skin from cancer. A new study, however, suggests that it can also cause vitamin D deficiency.

Vitamin D is important for bone health as it helps to absorb calcium. Helps for the normal functioning of the nerves and muscles, as well as in strengthening the immune system.

Vitamin D deficiency can lead to a reduction in bone density, and this gradually increases the risk of fractures and osteoporosis.

And while some groceries naturally contain vitamin D, such as fish or beef liver, it is mainly about very small quantities. The best source of vitamin D is exposure to sunlight. They penetrate the skin and in the form of cholesterol (7-dehydrocholesterol) are converted into the active form of vitamin D-3.

Scientists from the University of California have studied existing clinical studies of vitamin D deficiency and concluded that sunscreen with a 15 or more protective factor can reduce vitamin D production by as much as 99%.

Therefore, they recommend twice a week for at least half an hour to pass in the sun without applying a protective factor. That amount of exposure to sunlight will not increase the risk of skin cancer, and the body will maintain an optimal amount of vitamin D.
