The influence of environmental and core temperature on cyclooxygenase and PGE2 in healthy humans. Social stress in particular is one of the most well-known and robust factors for physiological reactivity. During whole-body cold exposure, the vasoconstrictor response is not limited to the hands, but is widespread throughout the peripheral shell. The decrease in peripheral blood flow reduces convective heat transfer between the body's core and shell (skin, subcutaneous fat, and skeletal muscle) and increases insulation. One man who’s leading the research into cold water swimming is Prof Mike Tipton, an environmental physiologist at the University of Portsmouth. However, the human body can adapt relatively well to heat and cold environments, and recent studies have also elucidated that particularly heat stress might be even highly beneficial for human health.
