New evidence on the mechanisms of action of balneotherapy remains a debated and complex topic, due to limited knowledge and the great heterogeneity of mineral waters and thermal muds.
Three main questions guide this reflection:
Why is it so difficult to evaluate the mechanisms of action of balneotherapy?
How can we study them?
What do we know today thanks to research?
The difficulty arises from the complex composition of waters and muds – with organic, inorganic, and microbiological components – and from their great variability worldwide. The therapeutic effects are probably the result of a combination of non-specific mechanisms (related to mechanical and thermal stimuli) and specific mechanisms (linked to chemical and biological constituents).
Studies can be preclinical (on cell cultures or animal models) or clinical in humans. Preclinical studies have the advantage of isolating individual effects, but they do not always faithfully reproduce real-life conditions.
Available evidence shows that balneotherapy exerts several effects:
Analgesic, also explained by the “Gate Control” theory of pain.
Muscle relaxant and neuroendocrine, with a reduction in distress and salivary cortisol.
