At The Feedback Farmacy, I use the miHealth Device for the 5 reasons listed below:
1. Built-in Biorhythm Clock
Bemer only has Alpha and Beta – good for morning/daytime
iMRS has Alpha, Beta, Theta and Delta – Theta and Delta good for evening/nighttime
miHealth goes beyond these frequencies and can not only be set to the time zone you are in but will go through the whole 24 hour Chinese Cycle where it cycles through each of the 12 Chinese meridians and their corresponding organ system to re-synchronize the body’s natural daily cyclical energy flow.
