“Using updated criteria as well as data obtained from the U.S. Census Bureau and the National Oceanic and Atmospheric Association, we looked at a range of environmental factors to pinpoint ‘hot spots’ across the country,” Dr. Myatt said. “The study factored in the average summer temperatures of each city and proximity to large bodies of water. Fitness and recreational sports facilities, as well as sports teams per capita were also considered for the rankings, knowing that more frequent exercise and crowded sporting events lead to a city’s overall sweatiness.”
