Freezing weather can mean frostbite and hypothermia unless a person is prepared. Today we talk about how to stay warm, dry and safe.
Frostbite is damage that happens when skin is exposed to extreme cold for too long. It mainly happens on the hands, feet, nose and ears.
People with minor cases of frostbite that affect only the skin may not suffer any permanent damage. But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold.
If blood vessels are damaged, people can suffer a gangrene infection. Sometimes the only way doctors can treat an injury like this is to remove frostbitten areas like fingers and toes.
Hypothermia is a condition that develops when the body cannot produce as much heat as it releases. Signs of hypothermia include uncontrollable shaking, very slow breathing and difficulty thinking clearly. Hypothermia can lead to death if the person does not receive help.
