Can humans survive in Fahrenheit?
The maximum body temperature a human can survive is 108.14°F. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably. Cold water draws out body heat. In a 39.2°F cold lake a human can survive a maximum of 30 minutes.
