Swim lessons are one of the best things you can do for a child. They build water confidence, develop a lifelong skill, and get kids comfortable in and around water from an early age. But outdoor swim lessons — at community pools, waterparks, and summer camps — mean extended UV exposure during some of the
If you're a man who burns easily, especially on the scalp, the back of the neck, or the ears, you've probably tried sunscreen, hats, and hoping for the best. None of them work particularly well in the water. Sunscreen washes off. Regular hats fly off. And hoping for the best leaves you spending the evening
For many people going through or recovering from chemotherapy, being in the water is one of the most joyful and restorative things they can do. Swimming reduces stress, improves circulation, and brings a sense of normalcy back to everyday life. But chemotherapy changes the skin's relationship with the sun.

Few places on earth match the Galapagos Islands for snorkeling. Swimming with sea lions, penguins, marine iguanas, and whale sharks is an experience that stays with you forever. So does a severe sunburn if you go unprepared. The Galapagos sits directly on the equator. UV levels are extreme year-round, and the combination of equatorial sun,
The Maldives is one of the most stunning snorkeling destinations in the world. Crystal-clear water, vibrant coral reefs, and endless sunshine. But that same sunshine — reflected off the water — makes sun protection one of the most important things to pack. Water reflects up to 50% of UV radiation back at you, which means
When people think about sun protection, they usually focus on shoulders, faces, and backs. The scalp is often an afterthought. Yet it is one of the most exposed and vulnerable areas of the body, especially in and around water. Sunburn on the scalp is common, painful, and often underestimated. Water makes this risk even
