Research shows the minimum effective TENS treatment session for period pain relief is 20 minutes. However, PowerDot can be worn for longer periods, even beyond 8 hours. The Period Pain Relief Program in the PowerDot App allows you to determine a timeframe between 30 and 90 minutes, and the intensity level. Once you complete a session, it is safe to start another session, if you need additional pain relief.

There is no evidence that suggests using PowerDot for multiple hours is unsafe. However, we do not recommend sleeping with the device on, as you should always be aware of the stimulation.
