Frostbite is a medical condition that occurs when skin and underlying tissues freeze due to exposure to extremely cold temperatures. It typically affects areas of the body that are most exposed, such as fingers, toes, ears, and the nose. Symptoms include numbness, tingling, and a change in skin color, which may appear white or grayish. If not treated promptly, frostbite can lead to serious complications, including permanent damage to the affected tissues. In severe cases, it may require surgical intervention or even amputation. To prevent frostbite, it is important to dress warmly and limit time spent in cold environments, especially during winter months.
