What are burns?
-
Burns are tissue injuries. They are most often caused by heat (like fire or hot water), which is known as a thermal burn. Other types of burns include chemical burns, electrical burns, and radiation burns. Burns can vary in severity, and are referred to as first-, second-, or third-degree. First-degree burns are the least severe, while third-degree are the most severe. However, third-degree burns are actually not normally painful because the burn has killed the nerves that signal pain.

Johns Hopkins Medicine answered:A burn is damage to your body’s tissues caused by heat, chemicals, electricity, sunlight or radiation. Scalds from hot liquids and steam, building fires and flammable liquids and gases are the most common causes of burns. There are two levels of burns:
Partial thickness burns affect only the outer layer of the skin, and cause pain, redness, and swelling. First degree burns (which effect just the epidermis) and second degree burns (which effect the dermis) are partial thickness burns.Full thickness burns affect both the outer and underlying layer of skin, and cause pain, redness, swelling, and blistering. They may extend into deeper tissues, and cause white or blackened, charred skin that may be numb. Third degree burns are full thickness burns.A burn is damage to your body’s tissues caused by heat, chemicals, electricity, sunlight or radiation.

Dr. Alfa Diallo of MDLIVE answered:Burns are injuries that disrupt the protective and regulatory processes of the skin. Most burns are thermal and occur when skin is exposed to temperatures over 115 degrees. Various factors determine the severity of a burn, including the intensity of heat, size of the exposed surface, and amount of time one is exposed to the heat. Burns can be classified in the following manner:
• First degree - Superficial burn that involves the outermost layer of dead skin cells (the epidermis). This is classically seen with sunburns and usually heals without scarring.
• Superficial second degree - A burn which involves the upper layer of living skin cells (dermis). These types of burns result in blistering and reveal tender tissue (dermis) that still appears pink. Often these also heal without scarring.
• Deep second degree - A burn which involves deeper layers of living skin cells (dermis). Unlike superficial second degree burns, the dermis that appears is white and often heals with scarring.
• Third degree- Full thickness burns that involve tissues such as nerves, tendons, vessels and fat beneath the dermis. Such burns are very serious and often require surgical intervention to allow for proper healing.Burns are injuries that disrupt the protective and regulatory processes of the skin.

Burns are a type of traumatic injury caused by thermal (heat such as fire, steam, tar, or hot liquids), electrical, radiation (UV rays or radiation treatments), chemical, or electromagnetic energy. Burns are classified as first-degree (mild), second-degree (moderate), or third-degree (severe), depending on how deep and severe they penetrate the skin's surface.
An open flame is the leading cause of burn injury for adults, while scalding is the leading cause of burn injury for children.
Burns can cause swelling, blistering, scarring, and, in serious cases, shock and even death. Burns also can lead to infections because they damage the skin's protective barrier. After a third-degree burn, individuals need skin or synthetic grafts to cover exposed tissue and encourage new skin to grow. First- and second-degree burns usually heal without grafts.
When tissues are burned, fluid from outside the cells leaks into the tissues from the blood vessels, causing swelling and pain. In addition, damaged skin and other body surfaces are easily infected because they can no longer act as a barrier against invading organisms.
More than two million people in the United States require treatment for burns each year, and between 3,000-4,000 individuals die of severe burns. Older people and young children are particularly vulnerable. About 20% of burns occur in children younger than age five, and most of these are scald burns from hot liquids. About 60% of burns occur in the 18-64 year-old age group. About 10% of burns occur in older adults, mostly scald burns from hot liquids. Men are twice as likely to have burn injuries as women.
The skin is the body's largest organ, covering the body. In addition to serving as a protective shield against heat, light, injury, and infection, the skin also regulates body temperature. The skin also stores water and fat, is a sensory organ, prevents water loss, and prevents the entry of bacteria.
