Frostbite is freezing of body tissue. It’s caused by exposure to extreme cold temperatures. Mild cases of frostbite affects just the skin, however, the damage can go deeper. Frostbite affects the extremities of the body including: nose, fingers, toes, ears and cheeks.

Signs of frostbite
The earliest sign that the body temperature begins to fall below normal (hypothermia) is shivering. This is actually good since the body tries to regulate its temperature. However, prolonged exposure to extreme cold temperature can have the following symptoms: numbness and loss of     pain sensation, cold skin that feels hard and solid, confusion, loss of function, blistering, color change from white, to red to purple, and slurred speech. When you notice these signs to a person, make sure to do the following first aid procedures:

• Take the person out of the cold.
• Wet clothes absorb heat from the body. Change to dry clothes as soon as possible.
• Submerge the patient’s body in warm (not hot) water for at least 20 minutes. Remember that the patient’s pain receptors are numb so don’t let him control the temperature.
• Don’t use direct heat such as heating pads from flat iron and fire from the stove.
