Is controlling homeostasis a conscious or unconscious process?

It is an unconcious process

Explanation:

Homeostasis is when the body is made sure to have a constant environment inside so that the body can work at it's optimum conditions constant temperature, constant pH etc ... you do sweat when you feel hot but you can't control it... your mind just tells it to... vadodilation and vasoconstriction for a constant temperature occurs for a constant temperature as well(when vessels dilate and constrict), your mind allows the vessels to do so without you thinking about it.
