What is TENS therapy?

A TENS is low intensity but high-frequency stimulation pulse which occurs about 100 times a second. Our body is a very complex system of nerve cells through which electrical signals travel. The exact way by which this system works is still entirely not wholly known, though medical science quite well understands the two regions responsible for these signals, the brain, and the nerve receptors.

TENS used because of their ability to interfere with the communication happening between these two parts of the body and get rid of the pain temporarily or permanently. Interruptions caused by TENS also enforce the production of endorphins in higher quantities which aid in repressing and minimizing the pain signals.

The process of pain can be understood as nerve endings present all over the body detect uncomforting or stimulating signals and pass them on to the area of the pain that travels throughout the body and towards the spinal cord. From the spinal cord, the pain signals reach the subconscious part of the brain.

The brain then pickups and intercepts the messages and produces a response accordingly such as giving the sensation of pain when a body part is hurt. TENS therapy requires the use of a TENS unit which sends low voltage, high-frequency electric pulses to the nerve cells and stops the pain receptive signals from reaching the brain.

Why should we use TENS machines?

TENS machines are used as an alternative form of pain-killing medication by many people who did not find oral medicines helpful or productive. The TENS machine is a small lightweight and portable box which can be worn on the body itself or held in hand. It is a battery operated device which is attached to the body via electrode pads and conducting wires.

It sends out small electrical pulses that are transmitted to the body through the skin tissues and intercepts with the pain signals that are being sent to the brain by the nerve cells. By intercepting and suppressing the pain signals TENS units successfully minimize or completely get rid of the pain. If you are facing chronic pain or have muscle aches or spasms, TENS units can prove to be a real lifesaver for you.

Conclusion –

If you are suffering from chronic muscular pain or face muscle spasms on a regular basis or if you are a sports person, then TENS unit is the best product for you. Pain caused due to stiffened muscles, spasms and other reasons can last a long time if not taken care of properly.

TENS unit provides an easy and fast way to relieve yourself of the agonizing pain by blocking the receptor signals sent by the nerve fibers of your body to the brain. It also encourages the production of endorphins which are a natural painkiller. So above given is a list of top 10 TENS units that you can buy online.
