Usually, it takes some prolonged or repetitive exposure.
Windchill alone is not predictive; it likely only has relevance if the actual temperature is between -5 degrees Celsius and -25 degrees Celsius. Above that, the risk is low no matter how windy it is, and below that, the risk of frostbite is high regardless of the windchill.
There are some promising treatments for frostbite available in a hospital setting. The earlier (within minutes) the treatments are provided after rewarming, the better. So, if in doubt, go get assessed at a hospital/health care centre ASAP if you believe you have frostbite.
There is no benefit to this, and it might cause harm. Rapid rewarming in hot water is the best way to begin treating frostbite.
Unlike a frozen piece of meat, studies show that rewarming your frozen hands or feet in hot water quickly is best. The water should be hot (34-40 degrees Celsius) and tolerable to put an unprotected hand in, but not boiling.
Alcohol can lower the body core temperature during cold exposure and increase the risk of hypothermia. Alcohol can also alter sensation and make you unaware of frostbite.
