RESUMO
In this study, 10 healthy students were subjected to experiments. They bathed in plain hot spring water and hot spring water with 2% Togol mud at 39°C for 10min at an interval of 1 week. No difference in the change rates of pulse rate and blood pressure was observed between the two types of bathing. Forehead and oral temperatures decreased slightly after bathing in plain hot spring water. However, after bathing in hot spring water with Togol mud, the forehead temperature tended to be higher than that before bathing while the oral temperature increased significantly after bathing. Skin surface temperatures on the chest wall, left instep, and right forearm increased significantly after both types of bathing. Changes in the skin temperature after bathing in hot spring water with Togol mud tended to be greater than those after bathing in plain hot spring water. Eight out of 10 students felt warmer after bathing in hot spring water with Togol mud. These findings suggest that bathing in hot spring water with Togol mud is useful for medical care.
