The infographic details the progression of frostbite across four clinical stages: Normal (no damage), Frostnip (reversible redness and numbness), Superficial frostbite (skin feels warm, blisters may form within 24-36 hours), and Deep frostbite (numbness, joint/muscle loss, blackened hard tissue after 24-48 hours). It also lists key symptoms including numbness, skin discoloration (red, white, blue, grayish-yellow), waxy appearance, stiffness, and blistering upon rewarming.
