When Damage to skin and underlying tissues caused by prolonged exposure to extreme cold?

Damage to skin and underlying tissues caused by prolonged exposure to extreme cold is known as frostbite. It occurs when body tissues freeze, leading to the formation of ice crystals that can cause cellular damage and, in severe cases, necrosis. Symptoms include numbness, tingling, discoloration, and, in advanced stages, blistering and tissue death. Immediate medical attention is critical to minimize damage and prevent complications.
