The human body is specifically designed to operate inwardly a narrow heat range. In certainty, it goes to great length to maintain itself at an fitting temperature. If the body is too cold, blood flow is directed towards the body core to keep up heat and shivering muscles generate further heat. If one is getting thaw, blood is pushed to the skin to radiate heat into the environment, and sweat take away excess heat by evaporative cooling. The redirection of blood reduce the amount of oxygenated blood heading to the brain, causing a insufficiency of alertness and the drowsiness one feels.
because it's cozy and relaxing...haha...
In thaw environment, as by soaking ur feet surrounded by hot water, more blood go 2 the warm parts of the body as the blood vessel of that part receive dilated. Since more blood goes to the periphery, smaller amount goes to the inner parts resembling brain & we feel drowsy. This happen also in radiator parts of the earth similar to Asia & Africa where due to increased atmospheric temprature, more blood go 2 skin2 cause sweating contained by order to hold the body temperature ordinary. People in these areas r more prone to bear a nap surrounded by the afternoon 4 same reason.
