Research Abstract

We examined the effects of carbon dioxide-rich water (CO_2) bathing on cutaneous vasodilatation and thermoregulatory responses. Cutaneous blood flow in the immersed skin was significantly increased during CO_2 bathing. Furthermore, the CO_2 bathing before sleep significantly decreased the core temperature and increased a parasympathetic nerve activity. Therefore, a positive effect of recovery from fatigue can be expected by CO_2 bathing.
