It may be hot in the summer where you live, but how hot is too hot? At what temperature does your body actually start to break down? In Death Valley, one of the hottest places on earth, the average temperature for July 2018 was a whopping 42.3 degrees C. That’s the warmest single month that’s ever been reliably measured in the world.
Seasons are getting more severe, especially summers, which are accompanied by heat waves that can be seriously deadly. In the U.S., extreme heat now causes more deaths than all other weather-related hazards. Heat waves around Europe have been killing record numbers of people, most notably since 2003, when unprecedented summer temperatures resulted in the deaths of over 70,000 people across Europe.
It shows no signs of slowing down, either, with all-time high temperature records being broken across the world. But how does heat actually kill you?
