It's more than relativity - it's a consequence of acclimatisation, which is the process of adaptation of the human body to ambient temperature environments. Humans may acclimate to cool temperature by increasing brown fat, which in turn may lead to improvements in glucose metabolism. These changes can be dampened or reversed following exposure to warmer temperatures. https://www.nih.gov/news-events/nih-research-matters/cool-temperature-alters-human-fat-metabolism https://www.nih.gov/news-events/nih-research-matters/cool-te...
