A thermal optimum is either a portion of a specified geological time span in which the average temperature was above that of the average temperature for the entire specified time or the optimum range within which a biological process may take place or the ambient optimal range for a species' niche.
In contrast, ambient temperature is the actual temperature, as measured by a thermometer, of the air (or other medium and surroundings) in any particular place. The ambient temperature (e.g. an unheated room in winter) may be very different from an ideal room temperature.
Temperature control (thermoregulation) is a homeostatic mechanism that keeps the organism at optimum operating temperature, as the temperature affects the rate of chemical reactions. In humans, the average internal temperature is widely accepted to be 37 °C (98.6 °F), a "normal" temperature established in the 1800s.
The ideal temperature for sleep is typically between 60°F and 67°F for most adults, says Martina Vendrame, M.D., neurologist and sleep medicine specialist at Lehigh Valley Health Network.
The Holocene Climate Optimum (HCO) was a warm period in the first half of the Holocene epoch, ... For other temperature fluctuations, see temperature record.
An operating temperature is the allowable temperature range of the local ambient environment at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and ranges from the minimum operating temperature to the maximum operating temperature (or peak operating ...
Nudging the temperature a little lower in winter or a little higher in summer is well worth it—especially if you're going on a long trip. According to the U.S. Department of Energy, you can save ...
This is mainly due to a more sluggish response of the counteraction mechanisms in lower parts of the body that are used to maintain the core temperature of the body at ideal values. [58] Seniors prefer warmer temperatures than young adults (76 vs 72 degrees F or 24.4 vs 22.2 Celsius). [54]
