What We Know About the Historic Heat Wave in 2022: How to Stay Safe in Extreme Heat
Heat illness can be incredibly serious, says Lewis Nelson, M.D., chair of emergency medicine at Rutgers New Jersey Medical School. “As our body temperature rises due to persistence in a hot environment, our vital body functions, such as enzymes and organs, begin to malfunction,” he says. “This leads to organ failure, and if untreated, can be lethal.”
While everyone is at risk for heat illness, some are more vulnerable than others, says Nicholas Kman, M.D., emergency medicine physician at The Ohio State University Wexner Medical Center. "Those at greatest risk for heat-related illness include infants and children up to four years of age, people 65 years of age and older, people who are overweight, and people who are ill or on certain medications." There’s also “greater risk with greater exposure,” he says.
Protect yourself from the sun when you’re outside by wearing a wide-brimmed hat, sunglasses, and sunscreen that says"broad spectrum" or "UVA/UVB protection." Dr. Nelson also recommends carrying water with you. “Maintaining adequate hydration is important, but it is equally important not to overdo it,” he says. “When we sweat, we lose salt and water, and if we only drink water without electrolytes, we run the risk of lowering our body sodium to concerning levels.” That’s why he suggests “eating regularly, along with drinking water or drinking electrolyte-containing beverages” like sports drinks.
Overall, Dr. Nelson says “keeping cool and safely hydrated is most important.” And, if you need to be outside in high heat, he recommends keeping tabs on how you feel and heading into cooler temperatures if you start to feel off.This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses.
