'Extreme heat is not just an inconvenience. It kills people'
Extreme heat has engulfed India in recent weeks with temperatures exceeding 120°F (49°C) in many areas. Thousands have died so far. Doctors and public health experts say the devastation comes as no surprise: when body temperature exceeds 104°F (40°C), heat stroke can cause a number of ailments and often death.
More Excerpts-
Humans sweat when their body temperature rises above its 98.6°F (37°C), the normal body temp. While sweating helps cool the body by taking heat with it as it evaporates, it can only do so much. Without a steady intake of fluids, dehydration will eventually take hold. Dehydration reduces blood flow and prevents blood from getting to organs like the kidney or the brain, leaving them with significant cell damage. Finally, these organs will start to shut down, causing further trauma. And from there a whole slew of negative medical effects take hold. For example, a highly-cited New England Journal of Medicine study documents how the intestine break downs unleashing bacteria will be released into the blood stream.
