TENS units work by delivering small electrical impulses through electrodes that have adhesive pads to attach them to a person’s skin.
These electrical impulses flood the nervous system, reducing its ability to transmit pain signals to the spinal cord and brain.
TENS is a noninvasive method for relieving pain. People who experience pain relief from this Tens unit may be able to reduce their intake of pain medications, some of which can be addictive or cause adverse side effects.
The same electrical impulses also stimulate the body to produce natural pain relievers called endorphins.
TENS units are also convenient because they are small, portable, and relatively discrete. People can carry a TENS unit in their pocket or clip it onto a belt to ensure that they have immediate access to pain relief throughout the day.
