When blood pressure is too high or too low, baroreceptors receive stimuli that trigger a necessary corrective response by effector organs. All mammals, including humans, can generate heat and have negative feedback loops that allow heat retention in cold environments and heat loss in hot environments. This process can elicit a significant behavioural response once the central nervous system determines if the threat presents a true danger to survival or physical integrity.
