HYDROTHERAPY: from the Greek meaning, quite literally 'water healing'. Hydrotherapy is zero impact exercise; the buoyancy of the water creates a weightless environment which helps to relieve stiffness and pain and supports weak joints. The water offers stress free support for joints and muscles and allows increased range of movement within the joints. Warm water helps with pain relief and promotes vasodilation, increasing blood flow to muscles and joints. Hydrotherapy helps to restore and maintain muscle tissue and improve circulation and cardiovascular fitness.
