The existence and function of an internal “organ clock” in living organisms is meanwhile scientifically proven as well as awarded (Nobel Prize in Medicine 2017, Hall, Rosbash and Young: Discoveries of Molecular Mechanisms Controlling the Circadian Rhythm). Our bodies and brains as well as planetary systems are changing frequencies at different times of the day. This has a profound impact on our wake/sleep cycles and our energetic/tiredness phases throughout 24 hours. While working and being active during the day, we “operate” on higher frequencies (brainwaves mainly in high beta ranges), whereas on lower frequencies during evening and night (alpha = awake but relaxed, delta and theta = sleep/dream). Sophisticated PEMF systems take this important fact into account and automatically deliver the appropriate frequency ranges according to the time the application is performed. This feature is only available in a very few PEMF devices, even though it represents an essential requirement in achieving the highest “biological” effect
