Sweating and shivering are responses created due to internal temperature fluctuations, and they are designed to bring the body back into

   Homeostasis

Explanation:  Homeostasis is first and foremost a tendency to strike a balance between the constituent elements / parts that are interdependent, and above all it relates to physiological processes. Logically, homeostasis therefore resists change or seeks to compensate for change through certain mechanisms (sweating, shivering, etc), exerted by an external factor (heat, coldness), in order to maintain a relatively stable equilibrium. This refers to the internal balance of the organism when there are external factors that cause that balance to be disturbed. Homeostasis is therefore the ability, in this case, of the organism, although it may also relate to the environment, to maintain approximately stability, internal balance despite changes caused by external factors.
