This clip shows Dr. Joseph Mercola discussing how exposure to sunlight can be good for your health, if done properly. Sunlight gives your body the Vitamin D it needs to help reduce your risk of cancer. The benefit comes from Ultraviolet B radiation, which reacts with the skin to make Vitamin D. However, the Ultraviolet A radiation in sunlight actually causes cancer, and must be avoided.

Dr. Mercola recommends skin products that block UVA radiation, and that don’t contain cancer-causing agents. Dr. Mercola is a physician and journalist who has written two New York Times best selling books. He also pens a newsletter that boasts over a million subscribers.

Sunshine Safety Tips:

• Proper exposure to sun can reduce cancer risk
• UVB radiation helps the body produce Vitamin D
• UVA radiation can cause cancer
• Find sun products that block UVA
• Avoid sun products made with carcinogens
