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.
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.

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 ...
Once the air temperature hits 122 degrees, our bodies can no longer dissipate heat and our core temperature rises. But another study cites a much lower limit of 89.6 degrees—the temperature at ...
Leidenfrost droplet Demonstration of the Leidenfrost effect Leidenfrost effect of a single drop of water. The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly.
Superficial burns may be managed with little more than simple pain medication, while major burns may require prolonged treatment in specialized burn centers. [2] Cooling with tap water may help pain and decrease damage; however, prolonged cooling may result in low body temperature .
Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead to the development of reticulated erythema , hyperpigmentation , scaling, and telangiectasias in the affected ...
