  2. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    There are four avenues of heat loss: convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such ...

    There are four avenues of heat loss: evaporation, convection, conduction, and radiation. If skin temperature is greater than that of the surrounding air temperature, the body can lose heat by convection and conduction. However, if air temperature of the surroundings is greater than that of the skin, the body gains heat by convection and ...

  4. Convection (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Convection_(Heat_transfer)

    Convection-cooling is sometimes loosely assumed to be described by Newton's law of cooling. [6] Newton's law states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings while under the effects of a breeze. The constant of proportionality is the heat transfer coefficient. [7]

  5. Newton's law of cooling - Wikipedia

    en.wikipedia.org/wiki/Newton's_law_of_cooling

    The statement of Newton's law used in the heat transfer literature puts into mathematics the idea that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings. For a temperature-independent heat transfer coefficient, the statement is:

  6. Thermal neutral zone - Wikipedia

    en.wikipedia.org/wiki/Thermal_neutral_zone

    In short, the skin must be able to get rid of 100 watts of heat in relatively warm environments, but also ensure that it does not lose too much more than this in relatively cold environments. The human outer or peripheral shell (skin, subcutaneous fat etc.) acts as an adjustable insulator/radiator with the main mechanism of adjustment being ...

  7. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    Latent heat loss, also known as evaporative heat loss, accounts for a large fraction of heat loss from the body. When the core temperature of the body increases, the body triggers sweat glands in the skin to bring additional moisture to the surface of the skin.

  8. Convection cell - Wikipedia

    en.wikipedia.org/wiki/Convection_cell

    Convection is caused by yeast releasing CO2. In fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling convection currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it ...

  9. Brown adipose tissue - Wikipedia

    en.wikipedia.org/wiki/Brown_adipose_tissue

    In neonates (newborn infants), brown fat makes up about 5% of the body mass and is located on the back, along the upper half of the spine and toward the shoulders. It is of great importance to avoid hypothermia, as lethal cold is a major death risk for premature neonates. Numerous factors make infants more susceptible to cold than adults:
