Protect Yourself from UV Radiation: in the summer months and beyondPosted on by
Fun in the sun will be on everyone’s list of things to do during the spring and summer months, but these are not the only times you should practice protective measures. Keeping yourself and others protected from UV radiation is an important, year-round responsibility. Ultraviolet (UV) radiation is a form of non-ionizing radiation that is emitted by the sun and artificial sources, such as tanning beds.
- Our natural source includes:
- The sun
- Some artificial sources include:
- Tanning Beds
- Mercury vapor lighting (often found in stadiums and school gyms)
- Some halogen, fluorescent, and incandescent lights
- Some types of lasers
Beneficial effects of UV radiation include the production of vitamin D, a vitamin essential to human health. Vitamin D helps the body absorb calcium and phosphorus from food and assists bone development. The World Health Organization (WHO) recommends 5 to 15 minutes of sun exposure 2 to 3 times a week.
- Sunburn is a sign of short-term overexposure, while premature aging and skin cancer are side effects of prolonged UV exposure.
- Some oral and topical medicines, such as antibiotics, birth control pills, and benzoyl peroxide products, as well as some cosmetics, may increase skin and eye sensitivity to UV in all skin types.
- UV exposure increases the risk of potentially blinding eye diseases, if eye protection is not used.
- Overexposure to UV radiation can lead to serious health issues, including cancer. Skin cancer is the most common cancer in the United States. The two most common types of skin cancer are basal cell cancer and squamous cell cancer. Typically, they form on the head, face, neck, hands, and arms because these body parts are the most exposed to UV radiation. Most cases of melanoma, the deadliest kind of skin cancer, are caused by exposure to UV radiation.
Anyone can get skin cancer, but is more common in people who:
- Spend a lot of time in the sun or have been sunburned
- Have light-color skin, hair and eyes
- Have a family member with skin cancer
- Are over age 50
To protect yourself from UV radiation:
- Stay in the shade, especially during midday hours.
- Wear clothes that cover your arms and legs.
- Wear a wide brim hat to shade your face, head, ears, and neck.
- Wear wraparound sunglasses that block both UVA and UVB rays.
- Use sunscreen with sun protection factor (SPF) 15 or higher, for both UVA and UVB protection.
- Avoid indoor tanning. Indoor tanning is particularly dangerous for younger users; people who begin indoor tanning during adolescence or early adulthood have a higher risk of developing melanoma.
