How it works
- TENS consists of small unit, attached to the wrist via electrode pads, delivers signal through the median nerve at the location on the underside of the wrist.
- These signals travel through the body's nervous system to the part of the brain which contros nausea, which causes the stomach to contrast irregularly, resulting in vomiting.
- By releasing a low-frequency pulse, it can adjust the vagus nerve signal straveling to and from the stomach, and can prevent or postpone the brain from transmitting nausea signals to the stomach, then reduces the nauseous sensation for the users.
