The yeast bath does not need heating. It is the heat energy generated by the enzyme strain itself, which has stronger penetrating power, can enter the human body more deeply, and has better cold-dispelling, dehumidification or detoxification effects. Sweating is physical heat energy, just like steaming steamed bread, but people can't stand it when the temperature is high, and it won't work when the temperature is low. Yeast bath can reach 60-80 degrees, but the somatosensory temperature is only about 40 degrees, which is harmful to human body.

It is almost impossible to sweat for the second time, but most guests in the enzyme bath can sweat for the second time.
