Quick Answer
Hypothermia can increase the risk of frostbite, but it does not directly cause frostbite. Frostbite occurs when skin and underlying tissues freeze, often due to prolonged exposure to cold temperatures. Untreated hypothermia can exacerbate this risk by impairing circulation and increasing the risk of tissue damage.
Understanding the Relationship Between Hypothermia and Frostbite
When a person experiences hypothermia, their body temperature drops below 95°F (35°C). This can lead to impaired circulation, which reduces blood flow to extremities. With reduced circulation, tissues in the extremities are more susceptible to damage from cold temperatures, making them more vulnerable to frostbite.
Frostbite Warning Signs and First Aid
Frostbite symptoms include numbness, tingling, or pain in affected areas, as well as pale or grayish skin. If you suspect someone has frostbite, move them to a warm location and remove any wet clothing. Gently immerse the affected area in warm water (not hot water) at 104°F (40°C) to 107°F (42°C) for 20 to 30 minutes. Do not use ice or heat packs, as these can cause further damage. After the warm water treatment, dry the affected area and cover it with a non-stick dressing.
Treating Hypothermia and Frostbite
If someone is experiencing hypothermia, call for medical help immediately. While waiting for help, use a warm blanket or emergency blanket to retain body heat. If the person is conscious, give them warm liquids to drink, such as tea or broth. Do not give them anything to eat. For severe hypothermia, use a technique called “active rewarming,” where you use a warm water bath to raise the person’s body temperature. Monitor the person’s pulse and breathing rate, and seek medical attention as soon as possible.
