Frostbite and hypothermia are two real dangers from cold exposure. Aside from cold exposure, risk factors for frostbite and hypothermia is alcohol consumption. Fingers, toes, ears, and nose are the first parts to freeze. Treatment for frost bite and hypothermia includes warming the person.
Frostbite occurs when the body is exposed to extremely cold temperatures. For the body to continue functioning under these conditions, blood circulation moves to the internal organs and brain, and away from the skin and extremities, for example, the fingers, hands, toes, and feet. The lack of blood circulation to these body parts causes frostbite. Hypothermia occurs when the body is exposed to extremely cold conditions over a prolonged period, and as a result the body temperature becomes dangerously low (95 F or 35 C).

Mountain Sickness
Altitude sickness (mountain sickness) is caused when a person's body is not able to adjust to a higher altitude. Acute altitude sickness symptoms fatigue, headache, dizziness, insomnia, nausea, decreased appetite, edema, and social withdrawal. Most cases of altitude sickness are resolved by going to a lower altitude. Altitude sickness can be severe and life-threatening if it progresses to high altitude pulmonary edema (HAPE). -
Cellulitis
Cellulitis is a bacterial infection of the skin and soft tissues that causes swelling, redness, tenderness and warmth. Treatment will involve antibiotics. Severe infection may require IV or intramuscular antibiotic injections. -
Cold Hands and Feet
When parts of your body get too cold, like your hands, feet, and sometimes other parts of the body, especially your ears and nose, they can be injured or react in different ways. Symptoms and signs of cold hands and feet include loss of sensation, numbness, tingling, itching, burning, unusual color of the affected area, and blistering. Types of cold injury include: frostbite, frostnip, immersion, pernio, Raynaud's phenomenon, cryoglobulins, and cold urticaria. The best treatment is rapid rewarming in the emergency department. -
Earache
Earache is pain in the ear. An earache can be caused by infections or fungus. There are types of ear infections to include otitis externa, otitis externa (swimmer's ear), otitis media, and myringitis. Symptoms of an earache include pain in the ear, fever, fluid seeping from the ear, and headache. Treatment of earache depends on the cause. -
Frostbite
Frostbite is a condition caused by skin exposed over a long period of time to cold exposure. Frostbite symptoms include burning, numbness, tingling, itching, and cold sensations in the affected areas. Deep frostbite there may be complete loss of sensation. Treatment of frostbite is best under medical supervision to minimize tissue damage. -
Gangrene
Gangrene describes death of body tissue due to reduced blood flow (dry gangrene), infection (wet gangrene), or the bacteria Clostridia (gas gangrene). Symptoms include skin discoloration, fever, pain, swelling, foul odor, numbness, discharge, rapid breathing, and rapid heart rate. Antibiotics and surgery are effective treatments for gangrene. -
Hand Injuries
Hand injuries can be divided into six categories. 1) cuts and lacerations, 2) fractures and dislocations, 3) soft tissue injuries and amputations, 4) infections, 5) burns, and 6) high pressure injuries. Treatment of hand injuries depends on the type of injury. -
Hypothermia
Hypothermia occurs when the normal body temperature of 95 F (35 C) or lower. Causes of hypothermia include exposure to a very cold or frigid environment (primary hypothermia), or when the body's temperature is altered by disease (secondary hypothermia). Treatment of hypothermia depends on the length of exposure. -
Insulin Reaction
An insulin reaction occurs when an individual with diabetes experiences hypoglycemia (low blood sugar) and becomes confused or unconscious. Causes of insulin reaction include improper medication dosing, exercise, or skipping meals. Common symptoms of a mild insulin reaction include dizziness, irritability, hunger, shakiness, rapid heart beat, and sweating. Treatment is generally sugar drinks, tablets, or wafers and monitoring insulin levels. -
Raynaud Phenomenon
Raynaud's syndrome (also called Raynaud's phenomenon) is a blood vessel disorder. The smooth muscle in the walls of arteries contract, causing "vasospasms" of the small vessels that supply blood to the extremities. The typical features of include changes in the color of skin from pale to bluish to red, which typically occur after exposure to cold temperatures. The disorder is sometimes referred to as "white fingers disease." -
Tetanus
Tetanus is an infectious disease caused by contamination of wounds from the bacteria Clostridium tetani, or the spores they produce that live in the soil, and animal feces. Symptoms and signs include: muscle cramps, lockjaw, weakness, and difficulty swallowing. Tetanus treatment incorporates antibiotics, wound cleansing, pain medicine, sedatives to control muscle spasms, and IV fluids.
