Is Thermoregulation Important To Re-Establish Homeostasis?

Homeostasis, the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. Any living creature needs to maintain a constant internal environment in order for their cells to work at optimal levels in order for them to survive and reproduce. Thermoregulation is a type of homeostasis that keeps the internal body temperature at a consistent level despite external stimuli. When the thermoreceptors in the skin/hypothalamus notice a change in the internal environmental temperature (stimulus) they send a signal to the hypothalamus where an appropriate effector is sent out to either increase or decrease the internal body temperature (response) to achieve homeostasis.

Following a group of 300 cyclists travelling the entire length of New Zealand from Cape Reinga to Bluff (a whole 2277 kms), they would go through extreme weather and be exposed to a variety of terrains. They all had to manage their own food and fluid intake as well as pack different clothing and gear to withstand the elements as to avoid problems like heat stroke, heat exhaustion or hypothermia. In the case of the cyclists, if he/she either contracted hypothermia or hyperthermia from extreme weather conditions, that would throw off the balance of homeostasis and therefore the body would be attempting to re-establish homeostasis.
The body must keep be able to keep a steady, stable, homeostatic environment so the body can work in optimal conditions. Humans are adapted to be able to keep the constant level of homeostasis as it is important to be able to have the optimal temperature for enzymes as while cycling through extreme weather or illness the body must be able to keep
