The body regulates temperature through a physiologic process called negative feedback mechanism. It involves the skin(which has a thermosensitive receptor) sending an impulse or message to the hypothalamus in the brain. The hypothalamus then send an impulse to the different body parts. For example, in a cold weather the blood vessels constrict, behavioural changes occur i.e covering self with a blanket, closing nearby windows and doors e.t.c. When all these occur and the body temperature is back to normal, an impulse is sent again to the hypothalamus that the temperature has been regulated. Then, again the hypothalamus inhibits the process.
