For someone with mild hypothermia, it is enough to cover them with heated blankets and offer warm fluids to drink. Blood rewarming.
What is considered severe hypothermia?
Severe hypothermia is life-threatening
Mild hypothermia (32–35 °C body temperature) is usually easy to treat. However, the risk of death increases as the core body temperature drops below 32 °C. If core body temperature is lower than 28 °C , the condition is life-threatening without immediate medical attention.
What are 4 signs of a severely hypothermic victim?

- Weak pulse.
- Clumsiness or lack of coordination.
- Drowsiness or very low energy.
- Confusion or memory loss.
- Loss of consciousness.
