Heat can be a deadly weather hazard, even outside of heat waves. In fact, most heat-related deaths occur during milder weather. When outdoors in the heat, wear lightweight, loose-fitting, and light-colored clothing to reflect heat and sunlight. If you will be spending time outdoors, hats are also a good idea to protect your face and scalp from harmful UV rays. Also, don’t forget to apply sunscreen liberally. Know the signs of heat-related illness and seek medical attention if necessary. For more heat-related resources and tips, visit
