People across the country are facing extreme heat and heat waves, even in regions not typically accustomed to such temperatures. Dr. Cedric Dark, an associate professor of emergency medicine at Baylor College of Medicine in Houston, Texas, where summer heat and humidity are common, provides advice for those spending time outdoors this summer. This guidance applies whether you're traveling to a hot area or experiencing an unexpected rise in temperatures.
When planning a vacation in high-heat areas, it's essential to pack sunscreen with at least 30 SPF, a portable misting fan, a hand towel for cooling off, and appropriate clothing. "Pack light-colored and loose-fitting clothing, breathable fabrics like cotton and linen and bring a loose-fitting hat. Tight clothing is going to retain heat," said Dr. Dark.
For outdoor activities, he advises limiting exertion during the hottest parts of the day and seeking shade whenever possible. "The main thing is to protect your skin from the sun," Dark said. He also emphasized staying hydrated with water instead of alcoholic or caffeinated drinks that can cause dehydration due to their chemical content. "By the time you are feeling thirsty, you are already mildly dehydrated."
These travel tips are also relevant for residents in areas experiencing unusual extreme heat. In these locations, it is important to monitor vulnerable populations such as pets, children, and senior citizens who may struggle with high temperatures.
Dr. Dark warns that if individuals begin feeling light-headed or experience symptoms like vomiting, nausea, or confusion while outside, they should immediately seek relief from the heat by finding a cooling center or an air-conditioned area if no cooling centers are available.
