Ben Greenfield on biohacking: what the evidence says · JRE #1069
SUBJECT: BIOHACKING
The short answer
Greenfield describes a claim that specific chakras vibrate at particular hertz frequencies (e.g. 528 Hz for the heart chakra), used to justify frequency-based sound therapy in his sauna sessions. Chakras are a concept from traditional South Asian medicine describing symbolic energy centers along the spine; Cleveland Clinic notes they 'aren't recognized by Western science,' functioning more as a metaphor for balance than as physical structures.
Not a true/false call. Every claim is logged with its sources; read the exhibits below.
There's this whole idea that like your root chakra, like your fourth chakra, your heart chakra vibrates at 528 hertz.
What the evidence says 01 / RECORD
Chakras are a concept from traditional South Asian medicine describing symbolic energy centers along the spine; Cleveland Clinic notes they 'aren't recognized by Western science,' functioning more as a metaphor for balance than as physical structures. The claim that specific chakras vibrate at specific, measurable hertz frequencies (such as 528 Hz for the heart chakra) is the premise behind commercial sound-bath practices, but Cleveland Clinic states there 'isn't much research into the science behind sound baths' and that a 2020 systematic review of singing-bowl studies found the evidence too limited to draw conclusions, calling for more research. Separately, general music and sound-based interventions do show modest, non-frequency-specific benefits for pain and stress in systematic reviews cited by the same source. No evidence in these sources supports a literal chakra-to-hertz correspondence or any special physiological property of 528 Hz specifically.
