Summer offers seemingly endless days of light and sun, but the sun also
can be dangerous, and it is important to protect yourself against its powerful rays. Here are some frequently asked questions about sun exposure:
Q: WHAT ARE THE BEST WAYS TO PROTECT MY FAMILY AGAINST SKIN CANCER?
Most of us cannot completely avoid exposure to the ultraviolet radiation of the sun. To lessen the risks, make applying sunscreen a part of every family member’s daily routine, and avoid sun exposure between the hours of 10 a.m. and 3 p.m., when the sun’s rays are strongest. Also stay in the shade when possible and wear protective clothing.
Q: HOW DO I DETERMINE THE MOST EFFECTIVE SUNSCREEN?
Broad-spectrum sunscreens are able to absorb both ultraviolet A and ultraviolet B radiation. Choose a broad-spectrum sunscreen with an SPF of 30 or higher for best protection. Sunscreens containing PABA (para-aminobenzoic acid) may cause allergic reactions and should be avoided. Remember to reapply all sunscreens frequently throughout the day, especially after swimming or working up a sweat.
Q: DO SUNSCREENS INTERFERE WITH THE ABSORPTION OF VITAMIN D?
There has been concern that sunscreen usage could result in vitamin D deficiency. Oral vitamin D supplements are a safe alternative to sunshine for achieving adequate vitamin D levels.
