What is the recommended first aid treatment for frostbite?

The recommended first aid treatment for frostbite is to immerse the affected area in warm water, specifically in the range of 80-85 degrees Fahrenheit. This method helps to slowly rewarm the frostbitten tissue and is crucial in preventing further tissue damage. Warm water provides a controlled environment that promotes gradual warming, which is essential because rapid rewarming can lead to additional injury.

Immersion in warm water also enhances blood circulation to the affected area, which is vital for recovery. It's important to note that the water should not be too hot, as this could burn the cold, numb skin and worsen the situation.

Other methods, like applying ice or rubbing the area, can actually exacerbate the problem rather than help it. Direct application of ice can further damage tissues and decrease circulation even more, while vigorous rubbing can lead to broken skin or further injury. Therefore, the correct approach emphasizes warmth through immersion in water at a safe, controlled temperature.
