Limit outdoor exertion, especially during the midday hours when the sun is strongest. If you must be outside, seek air-conditioned spaces whenever possible and check on neighbors or elderly relatives who may be vulnerable to the heat. Layering is not necessary given the warmth, but lightweight, light-colored clothing can help reflect sunlight.
