Thermal mud is spread over the affected areas of the body at a temperature of about 40°C.
On the one hand, the heat produces intense skin vasodilation and muscle relaxation; on the other hand, the thermal stress stimulates metabolism with the consequent release of hormones: cortisol and endorphins.
The former is a “natural cortisone” with anti-inflammatory value, the latter has an analgesic effect, also helping to raise the pain threshold on the treated person.

In this sense, thermal mud acts as a real drug, with a dual action and no potentially harmful side effects.
