Thermal neutrality

From Glossary of Meteorology

thermal neutrality

(Also called thermoneutrality.) The condition in which the thermal environment of a homeothermic animal is such that its heat production (metabolism) is not increased either by cold stress or heat stress.

The temperature range in which this minimum occurs is called the zone of thermal neutrality. For humans, this zone is 29°–31°C (84°–88°F).
