Benefits of 0.5 Hz Frequency

Deepest stage of NREM sleep

Maximum physical recovery and healing

Human growth hormone release

Cellular regeneration and repair

Immune system strengthening

What Does the Science Say?

Sub-delta frequencies below 1 Hz correspond to the deepest stages of non-REM sleep. During this state, the body releases growth hormone, repairs tissues, and strengthens the immune system. EEG studies show these ultra-slow oscillations are critical for memory consolidation.
