Independent terahertz testing
In 2023, Guangzhou Zhongsen Testing Technology measured the radiation output of the Tera-P90 (report ZSJC2023042607). The strongest band was 30 to 1,000 micrometres, which sits in the terahertz range. About a quarter of the total output fell in the terahertz band. You can read the full test report (PDF).
For what terahertz waves are and what the research says, see our terahertz article.
Using the Tera-P90
- Place the unit on a flat floor. Don’t use it on a slope or uneven surface.
- Switch on the power. The panel lights up and the standby light shows red.
- If the plates feel cold, press the heater switch to warm them. Turn it off again once they feel warm.
- Sit down and place your bare, dry feet on the plates, one foot on each. The working light turns green and the session starts at 30 minutes, strength 01.
- Raise the strength gradually with the + button until it feels comfortable. Lower it if the soles of your feet feel hot.
- The timer counts down in one-minute steps. At 01 the unit returns to standby.
- Turn the unit off and unplug it after each session.
Session limits
- The manual doesn’t recommend sessions longer than 30 minutes.
- After 30 minutes of continuous use, let the unit rest for 20 minutes.
- Don’t wear socks, and don’t put any cover over the plates.
