The use of external jet shower treatments is still limited even if their therapeutic benefit is well proven. They are a form of treatment which can be carried out using both normal and thermal water with the latter combining the advantages of the technique used with the water’s specific properties.

The jet can be used on all the body or directed at specific (also very small) areas of the body as is the case with ‘filiform’ showers. Not only does the jet work directly on the treated area but also works to stimulate the body in general and in particular the cardiovascular organs and nervous system.

The area which the jet treats is linked to both the surface tissues and the deep tissues and organs via nervous endings which are affected by the stimulation’s efficacy.

This is the reason why jet showers have proved useful as support therapies for treating mental problems and mood disorders (treatment of anxiety creating and depressive factors), and in cosmetic treatments especially as far as cellulite and other types of cosmetic problems are concerned.

The use of jet showers can differ in a large number of ways depending on the type of jet, water temperature (hot and cold showers, scotch showers and alternating temperatures) and jet pressure.

There is a wide range of types of showers which differ depending on the jet type (column, shower, horizontal) and particular mention must be made of filiform showers which emit a perpendicular jet of water measuring about half a millimetre in diameter. These types of shower which are particularly useful for treating skin problems are also used for their ‘abrasive’ properties and are extremely useful in treating acne.

Lastly the type of method used makes it possible to classify the showers according to the organ treated and the showers available include skin, liver and epigastric, perineal and plantar jet showers.
