Delta (Mid)
2.00 Hz
2 Hz is in the middle of the delta band of brain activity, as recorded by EEG (sensors on the scalp).
How well is this supported?
Measured directly, or defined by a published standard.
The band is a standard way of describing EEG recordings. Band edges are conventions, and what a person experiences varies. This is not medical information.
This is too slow or too fast to hear, so the button plays it moved by whole octaves. Start with the volume low.
About this number
2 Hz is in the middle of the delta band of brain activity, as recorded by EEG (sensors on the scalp). A 2017 glossary from the International Federation of Clinical Neurophysiology (IFCN) puts delta at 0.1 to under 4 Hz. Band edges are conventions and vary by source. Delta activity dominates slow-wave (deep) sleep.
What is said about it
What is said, not what was measured
Popular descriptions link this range to restorative sleep, cell regeneration and a stronger immune system. Slow-wave sleep is associated with hormonal changes that support immune responses. This is attributed to the sleep stage, not to a specific frequency.
