Minnesota is known for our cold and snowy winters, but staying warm and safe can be a challenge.

Preventing cold-related health problems
What is hypothermia?
Hypothermia is caused by prolonged exposure to very cold temperatures. When exposed to cold temperatures, your body begins to lose heat faster than it is produced. Lengthy exposure will eventually use up your body’s stored energy, which leads to a lower body temperature.
A body temperature that is too low affects the brain, making the victim unable to think clearly or move well. This makes hypothermia especially dangerous, because a person may not know that they are experiencing hypothermia and may not do anything about it.
While hypothermia is most likely at very cold temperatures, it can occur even at cool temperatures (above 40°F) if a person becomes chilled from rain, sweat, or submersion in cold water.
What is frostbite?
Frostbite is a type of injury caused by freezing. It leads to a loss of feeling and color in the affected areas, usually extremities, such as the nose, ears, cheeks, chin, fingers, and toes. Frostbite can permanently damage the body, and in severe cases can lead to amputation (removing the affected body part).
