Cold-induced thermogenesis, or the increase in energy expenditure upon cold exposure, indicates metabolic stress, as such, cold-induced thermogenesis may signal an appropriate stimulus to improve metabolic health. Cold acclimation may alter cold-induced thermogenesis due to changes in (non)shivering thermogenesis and blood flow. The main aim of this research is to compare the energy expenditure responses, during a standardised cold stress (\~ 9°C air temperature, maximum 1 hour), of Siberian adults with Western European adults. The subjects will be individually matched for age, sex, body mass and height. It was hypothesised that cold-induced thermogenesis will be reduced in the Siberian population.
