Regulation of body temperature


It is known that humans beings are warm blooded and thus are able to regulate its internal temperature. This is done by the heat/energy by the metabolism of food in the body. The ability to keep the body temperature within certain limits despite changes in external environment is called thermoregulation. There may be differences in the heat production and heat loss in different parts of the body, the circulating blood helps to bring it to a mean temperature. Two ways of thermo regulation used by mammals is:
1) Physiological regulation: during cold weather the body adapts to different mechanisms to regulate body temperature- like constriction of surface capillaries or shivering which raises the metabolic rate. In hot weather the body sweats to lower the body temperature.
2) Behavioral regulation: a person after sitting in the sun to warm up may want to cool down and thus may shift into the shaded area.

Some variations observed in body temperature in relation to food are:
• Specific food intake- may cause increase or decrease in body temperature.
• Alcohol intake- produces a fall in body temperature.
