Nothing can ruin a vacation like a bad sunburn. Not only will you feel miserable; you’re also doing permanent damage that can increase your chance of skin cancer. It only takes a few minutes to protect your skin and your fun, so don’t skip it! The Polyclinic’s Dermatology department offers some useful tips on how to protect yourself as you enjoy the summer sun. Make sure you choose a broad spectrum sunscreen that will provide protection against both UVA and UVB. Those that contain titanium dioxide or zinc oxide are the most effective. Generously apply sunscreen to all exposed skin. Sunscreen should have an SPF of at least 30. Reapply every two hours, even on cloudy days and after swimming or perspiring. Wear protective clothing. Consider a long-sleeved shirt, pants, and a wide brim hat and sunglasses. Use caution near water, sand, and snow as they reflect the damaging rays of the sun. High altitudes, for example when hiking or skiing, also can put you at risk for sunburn. Protect children from sun exposure by applying sunscreen. Physical blockers such as clothing and hats are best for children. Tanning beds are not safe! UV light from the sun and tanning beds causes skin cancer and wrinkles. If you want to look like you have been in the sun, consider using a self-tanning product and continue to use sunscreen daily.
