Frostbite can develop quickly in extreme cold, experts say

Health experts say frostbite and hypothermia can set in within minutes in very cold or windy conditions, and note that an internal temperature drop to about 95°F can cause mild hypothermia; they also report warming centers and backup shelters are operating and recommend keeping boots, a hat and gloves in a vehicle.

Health experts are warning that very cold weather and wind chill can lead to frostbite and hypothermia in a short time. They said colder temperatures speed how quickly these conditions develop. The body’s normal internal temperature is about 98 degrees Fahrenheit, and a drop to about 95 degrees can bring mild hypothermia with signs such as reduced coordination and dizziness. Experts also described visible changes from frostbite and noted community warming options are available. What experts said: - Frostbite and hypothermia are linked to how long someone is exposed and how cold it is, and can occur within minutes under strong wind chill. - A drop in internal body temperature to about 95°F can produce mild hypothermia with symptoms like dizziness and impaired coordination; people may look unusually disoriented. - Frostbite can show as wrinkling, a waxy appearance of the skin, and loss of circulation, and it can occur more rapidly in people with poor circulation. - Officials reported that backup shelters and warming centers are operating in the area during the cold spell. - One practical suggestion reported by experts is to keep boots, a hat and gloves in a vehicle so spare winter clothing is available if needed. Summary: Frostbite and hypothermia can develop rapidly in very cold or windy conditions, which raises health concerns for people who spend time outdoors or who have circulation issues. Officials have activated warming centers and backup shelters, and experts noted keeping spare winter clothing in vehicles. Undetermined at this time.
