This blocks pain signals from reaching the brain and stimulates the natural production of endorphins to raise your threshold for pain perception. It also helps to relax contracted muscles too, so your period pains are eased within no time. These electrical signals are based on a proven medical therapy known as TENS. TENS stands for Transcutaneous Electrical Nerve Stimulation.
