Information about sand baths in the Island of Porto Santo’s carbonate biogenic sand

Porto Santo’s sand has long been used to treat musculoskeletal disorders (rheumatic and orthopaedic diseases) such as rheumatoid arthritis, arthrosis, gout, osteoporosis and fibromyalgia.

The sand on Porto Santo is carbonate biogenic sand and it has specific physical, chemical and thermal properties. The grains are flat and very fine and adhere easily to the skin. It is rich in minerals such as magnesium, calcium, phosphorous, sulphur and STRONTIUM (a natural anti-inflammatory), among others. Due to its composition, the sand can remain at a high temperature for quite a long time.

More Informations


The recommended treatment plan consists of a minimum of 10 sand bath sessions, each lasting 20-30 minutes, on consecutive days.

Studies suggest that the benefits begin to be noted after the 5th day (10 sessions).

Appointment with the doctor (optional)

You should wear swimming trunks (men) or a bikini (ladies) in order to expose as much of your skin to the sand as possible. A bathrobe and slippers will be provided by the spa.


Treatments are not recommended for people who suffer from cardiovascular problems, low blood pressure, uncontrolled high or low blood pressure, peripheral respiratory failure / varicose veins or kidney failure, among others.

Scientific Studies

Findings proven scientifically through studies conducted by the University of Oslo (Norway) and the University of Aveiro (Portugal); information based on the studies conducted by Professor Celso Gomes and Engineer João Baptista, researchers at the GeoBioTec Research Unit of the University of Aveiro’s Foundation for Science and Technology. These studies offer a great deal of information, relevant to therapeutic use, about the physical, chemical and thermal properties of the carbonate biogenic sand found on the Island of Porto Santo.

The Treatment

Before starting the treatment you will be asked to fill in a questionnaire about your health, your blood pressure will be checked and you will have to drink fluids. Once the pre-treatment procedures have been completed you will be taken to the treatment area where qualified staff will assist you.

Each treatment consists of two sessions when you are immersed in hot sand. The temperature of the sand in the sand bath will be around 40-43ºC at the start of the treatment and over the recommended 25-30 minutes that the session lasts the temperature of the sand will fall to around 37-38ºC.

An acid is required in order for the sand to dissolve and release the minerals it contains so that they can be absorbed by your skin. This is provided by your own sweat, which has an acidic pH.

There will be a one-hour pause between sessions to give your body time to return to its normal temperature, and for you to relax and rehydrate by drinking fluids.

All the sand used for the therapy is thoroughly disinfected and is kept under strictly controlled conditions of hygiene, as well as being monitored constantly to ensure the correct temperature and humidity levels.
