Why More People Drowned Than Died of Heat in France's June Heatwave

When France sweltered in June, 48 people drowned trying to cool off in rivers and lakes, while only 18 died directly from the heat. The problem: as temperatures climbed above 100°F, desperate swimmers flooded unsupervised waters without lifeguards. France's emergency plans focused on preventing heat sickness, not preventing drowning when people sought relief.
