With summer arriving this week and the NOAA predicting a warmer-than-normal summer, it's important to get ready to deal with heat waves. High temperatures can kill by heating the body above its ability to cool itself off. In a typical year, about 175 people in the United States suffer heat-related deaths.North American summers are normally hot anyway; most summers see heat waves in at least one part of the country. East of the Rocky Mountains, they often combine high temperatures with high humidity. Our bodies' main method of cooling off is through the evaporation of sweat. Therefore, high humidity can cause problems even in relatively moderate summer temperatures, since it inhibits the evaporation of sweat.
