A burn is damage to the skin and sometimes to the underlying tissues. Burns can range from mild to severe. Some are fatal.
There are four main types of burns:
- First degree—mild, affect the outer layer of skin
- Second degree—deeper into the outer layer of skin
- Third degree—serious, all layers of skin are damaged
- Fourth degree—very serious, damage goes to nerves, muscle, tendon, and/or bone

Burns can be caused by:
- Heat or flame, such as:
- Hot foods, drinks, water, oil, or grease
- Direct heat such as stoves, heaters, or curling irons
- Direct flame
- Chemicals, such as:
- Cleaning products
- Battery fluid
- Pool chemicals
- Drain cleaners
- Sunlight (sunburns ) or tanning beds
- Electricity ( electrical burn )
- Radiation—nuclear, x-rays or radiation treatments for cancer
Burns are more common in males, children, and older adults. Other things that raise the risk are:
- Alcohol use
- Illegal drug use
- Absent or non-working smoke detectors
- Older housing
- Not watching children closely
- Using tap water hotter than 120°F (48.8°C)
Burn symptoms and signs vary. It depends on the type of burn.
The doctor will check your symptoms and health history. A physical exam will be done.
Testing is based on how severe the burn is. Tests may include:
- Blood tests
- Imaging—to see how deep the burn is, or if it has affected the inside of the body
- ECG—for electrical burns
Burns needs to be treated right away. Treatment depends on the severity and extent of the burn. The goal is to reduce damage to the tissues and prevent infection.
Minor burns are treated with first aid measures—such as cooling and covering the burn.
Serious burns need medical help right away. Treatment may include:
- CPR and first aid
- Airway and breathing support—with oxygen or mechanical ventilation
- Pain medicines
- Ointments and dressings—to promote healing and prevent infection
- IV fluids—to replace those lost from the burn
- Surgery, such as skin grafts—if burns are unlikely to heal
- Physical therapy—if burns are large
Most burns are from accidents. To reduce the risk:
- Watch children and protect them from hazards, such as:
- Stove burners, hot water, hot water faucets, and hot food and drinks
- Matches, lighters, candles, cigarettes
- Gas, chemicals, and firecrackers
- Electric cords and outlets
- Use smoke detectors and make sure they work
