Multiple inducible thermogenic mechanisms in the development of cold acclimatization

چکیده
Abstract Extreme cold environment can threaten human health and life through increasing the risk of myocardial infarction, stroke, frostbite, hypothermia. Insufficient heat production to maintain core body temperature is a major cause injury. To cope with stress, other mammals have developed capacity acclimatization adapt such harsh environment. Adaptive non-shivering thermogenesis ubiquitous form acclimatization. This review article systematically summarizes role three inducible thermogenic forms, including food intake, circadian rhythms, exposure in mediating under presents potential interventions for minimizing adverse consequences temperature.

The circulation in cold acclimatization.
The hand and forearm blood flow of the Eskimo has been found to be greater than that of a control group of white persons in a temperate climate both at rest at an ambient temperature of 20 C. and during acute cold exposure. Under cold stress, rectal temperature was better maintained in the Eskimos, though certain deep muscle temperatures fell more than they did in the white men because of the g...

0 N EXPOSURE to cold the body has a complicated physiological problem to solve. There is a limit to the heat it can produce to provide for an increased heat loss and during exposure of much severity a heat deficit is incurred. While peripheral tissues are cooling, the central body temperature must be kept within a very narrow range if the function of vital organs is to be maintained. If the acc...
