Watch out for sun damage this summer
VCU School of Pharmacy faculty, alumni and students have provided the Dr. Rx column for Richmond’s Fifty Plus magazine since December 2009. We now share those columns on the SOP website, as well, for those who might not have seen the most recent issue.
Serving as Dr. Rx for May 2014 was Jay Patel, a fourth-year student who, since this column was published, has graduated with his Pharm.D. degree.
Dear Dr. Rx: Is the sun dangerous to my health? What is the best way to protect myself?
Who doesn’t like to be in sun and enjoy the summer? We all do! Going to the beach, enjoying an outing in the sun with friends and family, visiting the pool or a water park are just some of the adventures that we might have in the summer.
But did you know that the sun could be damaging your health if appropriate measures are not taken? There are a variety of sun-induced conditions and skin disorders that we should pay special attention to and take appropriate precautions against.
Sun damage can manifest in various ways such as sunburn, premature aging, medication-induced sun-sensitivity and skin cancer, such as melanoma. Therefore, it is important to protect ourselves while we are out in the sun.
The best way to protect against sun damage is to avoid it. However, this is not always possible, especially if we have to be out in the sun for prolonged periods of time. Protective measures, such as wearing long-sleeved shirts, long pants and 4-inch brimmed hats, will help you stay safe from the sun’s damaging rays. Sunscreen is also very important when your skin is exposed.
Sunscreen comes in a variety of different sun protection factors (SPFs) and formulations. It will help protect you from sunburn. One of the ways to measure the effectiveness of various sunscreens is by looking at the SPF number. The higher the SPF number, the more effective it is at preventing sunburn. While the general recommendation is to use an SPF of at least 15 to prevent sunburn, an SPF of 30 or greater must be used to prevent skin cancer and by those individuals who tend to burn easily and tan minimally.
Moreover, if you plan to do water-related activities such as swimming or other vigorous activities outdoors, then water-resistant formulations should be utilized. “Water-resistant” sunscreens are effective for at least 40 minutes, while “very-water-resistant” products are effective for at least 80 minutes. Remember that if you are outside for an extended amount of time, you will need to reapply your sunscreen.
Initial treatment for sunburn is to remove yourself from the sun and to avoid further exposure. Usually minor sunburn can be treated with cool compresses or a cool bath. However, if you experience severe symptoms such as fever, weakness or seizures, or if you are on multiple medications that can exacerbate sunburn, please seek medical care immediately.
Some medications can put you at more risk for sunburn. Please check with your pharmacist to find out if you are taking one that increases your risk. Remember, long-term effects of sun damage might not be apparent for years after sun exposure. Last, but not least, remember always to dress appropriately and stay well-hydrated while you are out in the sun. Have a great summer!
