Negative ion decompression sports watch
It is recognized in the world that the key to measuring the effectiveness of exercise is heart rate. Exercise heart rate can tell you the real information of your body. If the heart rate is too high, the exercise is too intense, and the body water evaporates too quickly, which will not be beneficial to the body.

Far-infrared rays can be quickly absorbed by the human body, and when they penetrate into the human body, they will cause the resonance of the atoms and molecules of human cells. Through resonance absorption, a thermal reaction is formed, which promotes the temperature rise in the deep subcutaneous layer, expands the capillaries, and promotes blood circulation, which will hinder the Obstacles in metabolism are cleared, tissues are revived, and yeast production is promoted. Therefore, far infrared rays can improve and prevent various diseases caused by blood circulation and microcirculation disorders.
