Remarks by President Obama in Address to the United Nations General Assembly. United Nations. New York, New York. 10:12 A.M. EDT. PRESIDENT OBAMA: Mr. President, Mr. Secretary General, fellow delegates, ladies and gentlemen: It is a great honor for me to be here today. I would like to talk to you about a subject that is at the heart of the United Nations -- the pursuit of peace in an imperfect world.
Ultraviolet (UV) Exposure Is Not the Answer. Our bodies manufacture vitamin D when the sun's ultraviolet B (UVB) rays interact with 7-dehydrocholesterol (7-DHC) present in the skin. However, we can produce only a limited amount of vitamin D from UVB.
Does sunscreen inhibit the production of Vitamin D? Vitamin D is produced in the skin when itâs exposed to UV radiation from the sun. Sunscreens prevent the sunâs UV radiation from penetrating the skin and therefore may diminish production of vitamin D. Obtaining the balance of sufficient sunshine for vitamin D production whilst practising safe sun exposure is important.
