The mechanism behind High Electric Potential Therapy is that certain specially designed high potential electrical fields can help to heighten cell membrane potential and thus restore cell functions, and also possibly as a result regulate nervous system. The electrical fields are found to help improve blood circulation, increase metabolism, and stimulate the immune system. These effects can lead to a range of health benefits, including improved sleep quality.

Studies have been conducted to determine the effect.

A 2017 Osaka Japan study published as Electric Field Exposure Improves Subjective Symptoms Related to Sleeplessness in College Students: A Pilot Study of Electric Field Therapy for Sleep Disorder by Takashi Ohtsuki and team which conducted a small, randomized, single-blinded, placebo-controlled trial found that exposure to high-voltage electric fields improved subjective sleep symptoms in college students. The study collected objective data through sleep diaries and sleep-scans, demonstrating improvements in sleep length, refreshing, and sleepiness on rising. It concludes: "The beneficial effect of electric field therapy on sleep disorder in college students is… beyond a placebo effect. "

Another study conducted in Japan found that patients who underwent high potential therapy experienced significant improvements in their sleep quality. The study found that patients who received the therapy had an increase in deep sleep, a decrease in the number of times they woke up during the night, and an overall improvement in their sleep quality.

Also a study conducted in Taiwan found similar results, with patients who received high potential therapy experiencing significant improvements in their sleep quality. The study also found that patients who received the therapy had lower levels of stress and anxiety, which can also contribute to a better night's sleep.

Scientists have yet to pinpoint the exact cause of sleep disorders and provide a universal solution. But High Electrical Potential Therapy is believed to work by energizing the body's cells, improving circulation and metabolism. This reduces nervous stress, lightens the heart’s burden and improves mental & body’s calmness. A good amount of field data in Asia for years has also been examined and the result conforms the effect. In countries like Japan, Korea etc, sleep disorder improvement is now a formally recognized and written indication associated with High Potential Therapy.
