How cold does it have to be to get frostbite?

    “At or below 0 °C (32 °F), blood vessels close to the skin start to constrict. The same response may also be a result of exposure to high winds. This constriction helps to preserve core body temperature. In extreme cold, or when the body is exposed to cold for long periods, this protective strategy can reduce blood flow in some areas of the body to dangerously low levels. This lack of blood leads to the eventual freezing and death of skin tissue in the affected areas. There are three stages of frostbite. Each of these stages have varying degrees of pain.”

    It depends on the situation, but it seems like long term exposure at temperatures below freezing can eventually lead to frostbite

    When the temperature hits the freezing point (0 degrees Celsius, 32 degrees Fahrenheit), frostbite can begin to set in. Whether or not it actually will depends on insulation, time spent in the freezing temperature, etc.

    Just as a side note: if the wind chill factor makes temps -19 degrees F or lower, frostbite can occur in minutes. People who live in places like Alaska often don’t even venture outdoors at these temps as it can be very dangerous (frostbite can happen internally and affect the lungs, so just breathing air at those temps can be a serious hazard).
