Increase in dermal blood flow by the artificial CO2-bathing was confirmed by means of a Thermocouple flow meter and by a Laser doppler velocimeter.
The artificial CO2-bath was prepared with 50g tablet, made from sodium bicarbonate and succinic acid, putting simply in plain water at 38°C.
Dermal blood flow was increased nearly 5-fold by the simple bathing, and was further enhanced 1.3-fold by the artificial CO2-bathing.
It has been definitely shown by the artificial CO2-bathing that an increase in oral, finger tip, and forehead temperature and transepidermal water loss is significant compared to the plain bathing, so that the thermal effect equivalent to carbon-dioxated spring will be obtained.
