Today's spas and therapy pools can offer a multitude of specific health benefits, including relief from arthritis, back pain, and joint discomfort. Hydrotherapy delivers warm, soothing jets of water to various spots on your body know as 'pressure points'. When these points are properly triggered, your pain may lessen or even be eliminated. This occurs because warm water helps relax your muscles, and increases blood circulation. This allows for a greater range of motion in your joints, and facilitates muscle repair by increasing the flow of nutrient-rich blood to damaged cells. Additionally, when emerged in water, your body is about one-tenth its normal weight, creating an effect known as 'buoyancy'. This can be a key element of relaxation and stress relief because it removes weight from your joints. Spas can also help alleviate pain caused by exercise. When you exercise, your muscles can develop tears (TEHRZ) and a build-up of lactic acid, which slows muscle healing. The massage action of a spa can accelerate the repair process because it forces lactic acid to be carried away from your muscles. Hydrotherapy can be both soothing and relaxing, but if you're pregnant, have high blood pressure, heart disease, diabetes, or other physical conditions, it's a good idea to consult a physician before using a spa or therapy pool.
