The human body is like a heating system because we have an internal temperature "gauge", so to speak. Our bodies can tell when we are cold or hot and create sweat to cool us down if we get too hot.
The hot water on your skin opens your pores, and makes you sweat. The sweat evaporates, taking body heat away - making you feel cold. When your body is cold - you shiver.
the hot and cold water become together then they make an equal tempature. warm :)
Hot wax is a more gentle method than cold strip wax and is ideal for sensitive areas. The warmth of the wax opens the pores and supposedly results in less pain.
Hot tub chemicals are for the most part perfectly safe for the human body. The main chemical used is a chlorine product. It is safer the be exposed to chlorinated water in a hot tub, than it is to dirty hot tub water that has not been properly cleaned. The heat from a hot tub can make nasty organisms grow very quickly. There are also natural hot tubs, please see the following link for more information www.ahhnatural.com
because we are warm blooded.
In cold situations, the human body shivers to produce heat and the blood vessels constrict to retain heat, in hot situations the human body sweats to release heat. These are the ways the body thermoregulates.
It's bad if you can't feel cold because your body is supposed to be hot or cold. If you can't feel cold, see a doctor.
cold
Heat flows from hot to cold because when hot and cold bodies contact with each other (thermal contact), the fast moving molecules of the hot body collide with slow moving molecules of the cold body; therefore the molecules of hot body become slower and body becomes cool, and the molecules of other body (cold) becomes faster and the cold body becomes hot. Notice: when molecules of a body moves faster it's kinetic energy increase therefore temperature increases and it becomes hot.

no. Cold is just the heat in your body leaving so people just think they are cold. Hot is just heat coming in your body.
internal metabolism
The scrotum needs to be able to move away from the body and closer to it depending on the need for heat. If your body is to hot the sack will expand and move away from your body and if it becomes to cold it will tighten and move into your body. This is all done with sperm production in mind as if its too hot or cold the sperm will die.
