If it is a heart disease patient, massage to the reflex area of the organ, should be massaged for three to five minutes. For patients with severe heart disease, control the time or consult a doctor during massage. The importance of drinking water after massage: After being conditioned by a massage appliance, the reflex area is stimulated, so that the sediment and toxins accumulated in the reflex area and blood will be excreted from the body through the excretory organs such as the kidneys, ureters, and bladder. Therefore, after each massage, you must drink 300cc~500cc of water to excrete the toxins and sediments in the body. If you do not drink the water, the effect may be much lower. How e: 1.
