The coherence between brain and heart is incredibly important and shows many physical, as well as mental effects. This includes more relaxation, clarity, resilience and much more.
The HeartMath Institute has been researching this coherence for a long time. The insight: Our brain communicates permanently with our heart. Synchronize these two pulse generators with this neowake meditation.
To 1000 Hz:
The tone at 1000 Hz used to be used to calibrate audio equipment because it is at the center of human hearing. It also seems to have a modulating effect on the brain center, influencing cerebral neurons.
Other researchers believe that the 1000 Hz in the high gamma range has a healing effect on the body. The frequency used here should be listened to through loudspeakers.
To 197 Hz:
This high gamma frequency at 197 Hz is classically associated with activation of the heart on an emotional level. The effects are said to be subjectively perceived as warming.
Interestingly, the 197 Hz frequency is also the exact frequency of the sidereal day as known from astronomy. Again, it could be argued that our physical rhythms adapt to the universal rhythms and that there is an interaction.
Of course, this frequency can no longer be proven by classical conventional medical methods and is left to self-experience.
