Study suggests humans could have lower threshold for extreme heat than earlier thought

NEW DELHI: (Apr 1) Humans could have a lower threshold for extreme heat than previously thought, researchers have found - - a study result that they said can help cities prepare for summers in a warmer world.
The team from the University of Ottawa, Canada, exposed 12 volunteers to extreme heat and humidity to identify the point at which thermoregulation -- how one is able to maintain a stable body temperature -- becomes impossible.
The participants were subjected to 42 degrees Celsius with 57 per cent humidity, representing a humidex, or 'real feel', of 62 degrees Celsius.
