Wind chill
As any liquid evaporates, it leaves a feeling of coolness on your skin.
There are two ways that food can heat the body: one by increasing metabolism as in ingestion of too much iodine or by decreasing heat loss. Some things ingested like alcohol give the feeling of warmth as they increase blood flow to the skin and vasodilation, but that is the sensation of heat leaving the body.

Collagen
Your body heat does not get transmitted away from your body as readily in a dry air environment. When water comes into contact with your skin, the thermal transfer characteristics of your body heat into the environment are greatly increased.
The sweat is evaporating. Evaporation requires energy - heat. That energy is removed from the surface of your skin, and you feel the loss of energy as cold.
Wind chill
Yes, reduced blood flow to the skin raises body temperature. The skin provides a way for excess heat to exit, and so increased blood flow to the skin increases heat loss and decreases body temperature.
No, fat associated with skin prevents heat loss. Keratin and sebum associated with skin prevent water loss.
Diaphoresis, sweating
They dilate at the surface of the skin to release heat into the atmosphere, and they can also constrict to reduce heat loss through the skin.
If a blood vessel has a larger diameter then there is an increased rate of blood flowing through that vessel per unit of time. This increased rate causes an increase in heat through the vessel. Thus constricting the diameter of the blood vessel will cause a decrease in the rate of blood flow, causing less heat and therefore increased heat loss.
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
The primary site of heat loss from the body is the skin. Its not necessarily the head or feet. It is just the skin. "The skin is the primary site of heat loss. the circulating blood brings heat to the skin's surface, where small connections between the arterioles and the venules lie directly below the skin surface. Other heat losses occur through evaporation of sweat, through warming and humidifying of inspired air and through the elimination of urine and feces."

No, it drys out there skin and then they die from the heat and loss of moisture in there body.
The SUBCUTENOUS FAT LAYER which is made ou of fatty tissue that prevents the quick loss of heat and promote quick absorption of heat
Both processes are for heat loss or thermoregulation .
