What is the best treatment for hypothermia and how can it be administered effectively?

The best treatment for hypothermia is gradual rewarming of the body. This can be done by removing wet clothing, wrapping the person in warm blankets, and providing warm fluids to drink. In severe cases, medical professionals may use heated intravenous fluids or warm air blankets to help raise the body temperature. It is important to handle the person gently and avoid sudden movements to prevent further complications.
