What is a primary symptom of frostbite?

A primary symptom of frostbite is white or grayish skin. This occurs as the skin and underlying tissues freeze due to exposure to cold temperatures, leading to restricted blood flow. As the tissues freeze, they can lose their color, turning white or grayish as the normal blood supply diminishes. This discoloration is an important indicator and should be recognized early to prevent further tissue damage.

In cases of frostbite, the affected area may also feel cold and hard to the touch. It's crucial to note that early intervention can make a significant difference in outcomes, as rewarming and medical attention may be necessary to prevent further complications. The presence of white or grayish skin is a visual cue for individuals to seek help before the frostbite progresses.
