Hydro massage is a spa treatment that uses high pressure water jets as a massage tool. Jets are more powerful than those found in a standard bathtub or a Jacuzzi, and the water temperature is warmer. Traditionally, hydro massage includes diving; however, some massage units now have waterproof membranes that prevent water from touching the skin. If you have a heart disease or other medical condition, you should consult your doctor before you start the hydro massage therapy.
You should also talk to your doctor or therapist if you are pregnant, if you are cured of an injury or surgery, or you have high blood pressure. Avoid eating a big meal or drinking alcohol before your treatment.
