The aim of this study is to investigate whether or not cold vasodilatation reaction exists in macaques (Macaca fuscata and Macaca mulatta) and, if there exists any, to what extent they adapt themselves to cold. Cold vasodilatation reaction was observed in all individuals of six male Japanese monkeys and three of six rhesus monkeys. Time to first temperature rise after immersion into cold water was significantly faster in rhesus monkeys than Japanese monkeys. Tempearture of first rise after immersion and mean skin temperature during immersion were also significantly higher in Japanese monkeys than those of rhesus monkeys. No significant difference, however, was found in the highest skin temperature during immersion. Skin temperatures of these species did not return to the control level before immersion, even 30min, after withdrawing the fingers from the iced water bottle.
