Hydroxer uses the pressure of the water stream coming from the nozzles attached to the edge of the special tub for this operation. Their number is around 98, while they are divided into eight zones and adjustable according to individual needs. During the underwater jet massage itself, thanks to the temperature of the water and the action of fine water jets, muscles and mental tension are released. It also improves blood circulation in the tissues of the upper and lower limbs, which is used especially in patients suffering from peripheral blood circulation disorders. Acupuncture points can also be used to target certain areas of the spine, thus helping, for example, with problems with migraines and insomnia. Post-traumatic conditions and conditions after surgery, diseases of the musculoskeletal system, functional nerve disorders, arthrosis and some vascular diseases are also indications for receiving a massage. On the contrary, this method is unsuitable in case of acute infectious diseases, open wounds, states after thrombosis or varicose syndrome.
