Scalding is a type of thermal burn caused by boiling water and steam, commonly suffered by children. Scalds are commonly caused by accidental spilling of hot liquids, having water temperature too high for baths and showers, steam from boiling water or heated food, or getting splattered by hot cooking oil.

However, it is necessary to keep warm water at a temperature of 55–60 °C (131–140 °F) to inhibit the growth of legionella bacteria. The American Burn Association states that a scalding injury occurs when skin is placed in contact with water measuring 155 degrees Fahrenheit, or 68 degrees Celsius, for one second.
The depth of penetration depends on the frequency of the microwaves and the tissue type. The Active Denial System ("pain ray") is a less-lethal directed energy weapon that employs a microwave beam at 95 GHz; a two-second burst of the 95 GHz focused beam heats the skin to a temperature of 130 °F (54 °C) at a depth of 1/64th of an inch (0.4 mm) and is claimed to cause skin pain without lasting ...
Superficial burns cause pain lasting two or three days, followed by peeling of the skin over the next few days. [11] [21] Individuals with more severe burns may indicate discomfort or complain of feeling pressure rather than pain. Full-thickness burns may be entirely insensitive to light touch or puncture.

Ultraviolet light can cause burns to skin [15] and cataracts to the eyes. [15] Ultraviolet is classified into near, medium and far UV according to energy, where near and medium ultraviolet are technically non-ionizing, but where all UV wavelengths can cause photochemical reactions that to some extent mimic ionization (including DNA damage and ...
A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
Giant hogweed sap can make skin extremely sensitive to the sun, causing third-degree burns in a short period of time. This can blind people if it gets in an eye. If you encounter the plant, don't ...
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. [1] Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. [2] [3]
