Answer and Explanation:

In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:

The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
The metabolic rate falls so that the body generates less heat. You also become less active
Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
