Burns (including frostbite & sunburn)

Halie Bridges and Cassie Sherbon

Burn: an injury to tissues resulting from contact with heat, chemicals, electricity, friction, or radiant and electromagnetic energy. Burns are classified into three categories: 1st, 2nd, and 3rd degree. Frostbite and Sunburns are also types of burns. Treatment and recovery depend on the total area and severity or depth of the burn.

First Degree Burns: A first degree burn causes minor discomfort and some reddening of the skin. No blistering occurs, and the surface layers will peel in 1 to 3 days.

Second Degree Burns: A second degree burn involves the deep epidermal layers and always causes injury to the upper layers of the dermis. Also called a partial-thickness burn, a second degree burn will damage sweat glands, hair follicles, and sebaceous glands (oil producing glands), but will not completely destroy the skin. Blisters, severe pain, generalized swelling, and fluid loss are common with this type of burn.

Third Degree Burns: A third degree burn is characterized by complete destruction of the epidermis and dermis. Underlying muscles and bone are often involved in third degree burns. Third degree burns are insensitive to pain because of the destruction of the nerve endings.

Frostbite: Is damage caused to skin and other tissues due to extreme cold. At or below 0° C (32° F), blood vessels close to the skin start to constrict.

Sunburn: burn caused by exposure to harmful UV Radiation in sunlight. Serious sunburns can cause tissue damage and lead to secondary infections and fluid loss.

Cancer researchers have recently theorized that blistering (second-degree) sunburns during childhood may trigger the development of malignant melanoma later in life. Studies also show that adults that have had more than two blistering sunburns before the age of 20 have a much greater risk of developing melanoma than someone who experienced no such burns.
