Gradually increase the intensity level until you feel a light tingling sensation, as this varies among individuals and may change from day to day. Adjust the level during the session by increasing it if the sensation fades and decreasing it if it becomes too intense. The appropriate level is when you feel tingling without pain or discomfort in the tragus. If irritation occurs, shorten the stimulation time rather than lowering the intensity level to maintain effectiveness. As long as you feel the sensation without pain, you are using Nuropod correctly.
