Four Steps to Sun Safety

For some of us, nothing feels as good as basking in the warm sun. But keep this in mind: If you bask more than just a little, you're exposing yourself to some big health risks.

But you can do a lot to protect yourself. Start by understanding these four facts:

• Sunlight contains two types of ultraviolet (UV) rays—UVA and UVB. 
  Both can be dangerous. UVA rays penetrate deep into the skin and can weaken the immune system. That can make it easier for cancer to develop. UVB rays are the main cause of sunburn. Severe sunburns, particularly in childhood, increase the risk of skin cancer.
• Tanned skin is damaged skin. This damage builds up over time, contributing to premature aging of the skin and the risk of skin cancer.
• Use sunscreen with an SPF (sun protection factor) of 30 or higher. Be sure it protects against both UVA and UVB rays, and follow application directions.  
• Don't rely on the sun for vitamin D. Instead, get this bone-building nutrient from a healthy diet. Foods naturally containing vitamin D include fatty fish, such as salmon. Other foods such as milk, yogurt, orange juice and cereal often have vitamin D added.

5 risks to know 

No one is safe from the sun, including people with dark skin. However, the risk is greater if you have:

• Fair skin.
• Blue or green eyes.
• Blonde or red hair.
• A family history of skin cancer.
• Skin that burns, freckles or reddens easily.
