Most burns happen at home—and nearly 176,000 still kill yearly
In 2015 fire and heat caused about 67 million injuries, 2.9 million hospital stays, and roughly 176,000 deaths, concentrated in the developing world. U.S. data blame flames for 44% of burns and scalds for 33%. Kitchens and open cook fires remain the deadliest everyday workplaces.
A burn injures skin or deeper tissue through heat, electricity, chemicals, friction, or radiation such as ultraviolet sunburn. Superficial first-degree injuries look red without blisters and hurt for about three days. Partial-thickness second-degree burns blister, hurt intensely, and may need up to eight weeks. Full-thickness wounds can feel numb to light touch. Cooling with tap water eases pain and limits damage, but overdoing it risks hypothermia that complicates recovery.
American cause shares put fire or flame first at forty-four percent, then scalds at thirty-three, hot objects, electricity, and chemicals; about sixty-nine percent of injuries strike at home. Smoking lights a quarter of fatal house fires, heating devices another twenty-two percent. Chemical burns involve more than twenty-five thousand agents, mostly strong bases or acids, with deaths often after ingestion. Electrical injuries split at one thousand volts; children's cord and outlet accidents dominate low-voltage cases, and high voltage may wreck tissue invisible at the skin.
Poverty, smoking, and alcohol raise risk; colder climates see more fire burns, while open-floor cooking and childhood developmental disability drive harm in poorer regions. Among women worldwide, unsafe cook stoves loom large; among men, hazardous workplaces. Once tissue passes 44 °C its proteins begin to unfold and break down, and a burn covering more than 30% of the body sets off a body-wide inflammation that leaks fluid out of capillaries and drains blood volume. Prevention and triage—simple analgesia for shallow wounds, specialised centres for major ones—matter because the global toll is still measured in tens of millions of injuries each year.
