What Are the Benefits of SPF? How to Safely Enjoy the Sun This Summer.

As temperatures rise this summer, sun protection factor (SPF) should be a part of everyone’s summer routine. The MD Anderson Cancer Center suggests SPF protections of 30 or higher. In fact, Susan Y. Chon, M.D., advises that “[f]or sunscreen to do its job effectively, you should apply 1 ounce of sunscreen — the size of a golf ball — to every part of your body exposed to the sun.” 

SPF should be reapplied every two hours while outside. To remember when to reapply SPF, set a timer on your phone for reminders.

Wearing SPF as the UV index increases in the summertime has a multitude of benefits, such as reducing the likelihood of developing skin cancer, guarding the skin against early aging, and avoiding uncomfortable sunburns. 

There are two kinds of sunscreen to protect against sun rays, chemical and mineral. Both types protect skin against the sun. According to the MD Anderson Cancer Center, mineral sunscreens “reflect UV rays,” while chemical sunscreens “absorb UV rays”. 

Whether you're lounging on the beach, hiking in the mountains, or simply walking your dog in the summer heat, wearing sunscreen is essential. The benefits far outweigh the discomfort of a sunburn.
