The role of stable hydrogen isotopes in the thermoregulation and its regulation is poorly studied. We analyzed fluctuations in body temperature and changes in thermoregulation parameters in mice under conditions of reduced deuterium intake. The study was performed on male C57BL/6 mice that consumed water with a low (10 ppm) and normal (146 ppm) deuterium content. In 7 days, fluctuations of body temperature, locomotor activity, and oxygen uptake were assessed. Deuterium depletion in the body reduced the mean value of minute fluctuations of body temperature and the mean spectral density of minute fluctuations in body temperature in the 2-20-min periods. This attested to a stabilizing effect of deuterium depletion on the rhythms of body temperature fluctuations, without significant shifts in the thermogenesis parameters. Thus, drinking water with reduced deuterium content makes them less sensitive to external influences.
