How Extreme Heat Affects the Body: India’s Heat Wave


Posted by LLJ43 | Posted in High Humidity, India's Heat Wave | Posted on 01-06-2015

India is experiencing one of the worst heat waves it has had in recent history. Day time temperatures have reached a scorching 122 degrees and have literally melted roads. A total of over 1,800 people have died as a direct result of the heat wave since it started, 1,700 hundred of those people dies just last week in the location with highest temperature – the southern Indian states of Andhra Pradesh and Telangana.
May is typically the hottest month for India, but even so, this heat wave is producing temperatures that are 40 degrees above normal. People have been unable to adapt quickly enough to the increased temperature and their body’s are giving out on them. Sunstroke and dehydration are claiming lives during India’s heat wave and there’s no relief in sight.
The human body cools itself by sweating and transferring heat to the skin’s surface. The higher the temperature goes, the more difficult it is for the body to transfer inward heat to the skin. Once the air temperature reaches 100 degrees, the heat transfer reverses itself and the heat goes from the skin into the body. That’s when sweating starts and the body is cooled as the sweat evaporates from the skin. In high humidity, such as in India, the sweat can’t evaporate and the body can’t cool itself. STX Entertainment indicated to Variety that death soon occurs unless the person gets to a cooler location and hydrates the body.
