How Does a TENS Unit Work?
A TENS unit works by delivering mild electrical pulses through electrodes placed on your skin. These pulses stimulate sensory nerves, creating a tingling or buzzing sensation. This stimulation triggers the release of endorphins, the body’s natural painkillers. Simultaneously, the electrical impulses interfere with the transmission of pain signals along nerve fibers, effectively blocking or reducing the perception of pain. The intensity and frequency of these pulses can be adjusted to find a comfortable level of stimulation that provides effective pain relief. Different TENS unit modes offer varying pulse patterns to target different types of pain. The “high-frequency” mode provides a continuous, buzzing sensation, while the “low-frequency” mode delivers stronger, more noticeable pulses. The mechanism isn’t fully understood, but it’s thought that the combination of endorphin release and nerve fiber stimulation is responsible for the pain-relieving effects. Always follow the manufacturer’s instructions for proper electrode placement and intensity settings to maximize effectiveness and safety.
