Inside a heat chamber

Kreycik had almost everything on his side when he went running on that hot day: he was extremely fit, relatively young and was an experienced runner.

While some people are more vulnerable to heat than others, including the very old and young, no one is immune — not even the world’s top athletes. Many are expressing anxiety as temperatures are forecast to soar past 95 degrees this week in Paris, as the Olympic Games get underway.

Scientists are still trying to unravel the many ways heat attacks the body. One way they do this is with environmental chambers: rooms where they can test human response to a huge range of temperature and humidity.

CNN visited one such chamber at the University of South Wales in the UK to experience how heat kills, but in a safe and controlled environment.

“We’ll warm you up and things will slowly start to unravel,” warned Damian Bailey, a physiology and biochemistry professor at the university. Bailey uses a plethora of instruments to track vital signs — heart rate, brain blood flow and skin temperature — while subjects are at rest or doing light exercise on a bike.

The room starts at a comfortable 73 degrees Fahrenheit but ramps up to 104. Then scientists hit their subjects with extreme humidity, shooting from a dry 20% to an oppressive 85%.

“That’s the killer,” Bailey said, “it’s the humidity you cannot acclimatize to.”

And that’s when things get tough.
