Gynecomastia is a condition of overdevelopment or enlargement of breast tissue in men or boys. An imbalance between hormones causes growth. Estrogen causes breast tissue to grow; while all males produce some estrogen, they usually have much higher levels of testosterone, which stops estrogen from causing breast tissue to grow. Poor posture can cause pain and discomfort in your shoulders, neck, and back. When you slump in front of the computer, for example, your shoulders are hunched forward and your neck is bent down toward your chest. You may feel relaxed at first but this position places additional strain on your muscles and ligaments. Tourmalineis a natural gemstone called tourmaline in mineralogy. It has unique piezoelectric and thermoelectric effects that generate an electric charge when heated, pressured, or excited by other energy; it releases negative ions and emitsfar-infraredrays with a special electromagnetic wave protection function. Germaniteis a rare semiconductor element that has a small band gap that allows it to efficiently respond to infrared light. Two important characteristics of Germanium, as far as healthy function effects, are its natural ability to emit negative ions and the penetrationar InfraredRays into the human body.
