What is TENS therapy?

A TENS is a low-intensity but high-frequency stimulation pulse that occurs about 100 times a second. Our body is a complex system of nerve cells through which electrical signals travel. The exact way this system works is still entirely unknown, though medical science quite well understands the two regions responsible for these signals: the brain and the nerve receptors.

TENS are used because they can interfere with the communication between these two parts of the body and temporarily or permanently eliminate pain. Interruptions caused by TENS also enforce the production of endorphins in higher quantities, which aid in repressing and minimizing pain signals.

The process of pain can be understood as nerve endings present all over the body detecting uncomforting or stimulating signals and passing them on to the area of pain, which 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 picks up and intercepts the messages and produces a response accordingly, such as 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?

Many people use TENS machines as an alternative form of pain-killing medication because they do not find oral medicines helpful or productive. The TENS machine is a small, lightweight, and portable box that can be worn on the body or held in hand. It is a battery-operated device attached to the body via electrode pads and conducting wires.

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

Conclusion –

If you suffer from chronic muscular pain or regularly experience muscle spasms, or if you are a sportsperson, then a TENS unit is the best product for you. Pain caused by stiffened muscles, spasms, or other reasons can last long if not adequately treated.

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