külmavajadus
Külmavajadus refers to the physiological response of an organism to cold temperatures. It is a complex process involving a series of adaptive mechanisms designed to maintain core body temperature within a viable range when exposed to a cold environment. These mechanisms can be broadly categorized into behavioral and physiological responses.
Behavioral responses include actions taken by an individual to reduce heat loss or increase heat production.
Physiological responses involve involuntary biological processes. Vasoconstriction, the narrowing of blood vessels in the extremities, reduces
The duration and intensity of cold exposure, as well as individual factors such as age, body composition,
