Extreme heat is more than an issue of discomfort.
It forces the body into overdrive as it tries to stay cool through perspiration and evaporation. People in urban areas are at greater risk because the stagnant atmospheric conditions trap pollutants in the air, which, when breathed can trigger respiratory problems for many people. The effects of extreme heat can undermine your physical well-being so slowly and subtly that the dangers aren't apparent until it's too late. In regions of low humidity, the most common human response to extreme heat is dehydration. No matter where you live, it is important to recognize the real dangers of extreme heat and take action to offset its impact at its earliest stages.
