Our body starts constricting blood vessels transporting warm blood to the internal organs. where water temperatures can soar into the 90s. Even though some adults have been known to survive, profound hypothermia has occurred. That's because "the body loses heat about 25 times faster in water than in air." Hypothermia can develop in as little as five minutes in temperatures of minus 50 degrees Fahrenheit if you're not dressed properly and have exposed skin .

High-temperature reusable surface insulation (HRSI) has a black borosilicate glass coating, making this dark surface capable of standing up to the same high temperatures as the nose cone encountered.

Lost, wet and alone in a freezing, snow covered landscape, an Icelandic fisherman's story of survival against the odds reveals the human body's remarkable ability to adapt to the cold. At higher temperatures the body turns into scrambled eggs: proteins are denatured and the brain gets damaged irreparably. If the wet-bulb temperature is warmer than the skin temperature, metabolic heat cannot be released and can lead to potentially dangerous overheating depending on the magnitude and duration of the heat stress. We all know the "rule of three" for air, water and food(3 minutes without air, 3 days without water and 3 weeks without food), but we don't know the other limits of human survival.
