The rate changes
the outcome.

Red light works at any frequency. But pulsing it at specific rates — 10 Hz, 40 Hz, 100 Hz — produces measurably different effects. Some of those effects are backed by hard research. Some are emerging. Some are practitioner lore. Here’s the honest map.

Well-established
Continuous wave, published RCTs, decades of PBM research.
Emerging
10 Hz, 40 Hz, 100 Hz — real mechanism, growing clinical data.
Speculative
Rife-adjacent, 200–999 Hz. Practitioner-used, not peer-reviewed.

Watch what the rate actually does.

Tap any frequency. All three visualizations retime to that exact rate in real time. You’ll see why 10 Hz entrains and 100 Hz doesn’t — without reading a single paper.

10 Hz pulsing mirrors the alpha-wave state associated with relaxed awareness and the transition into sleep. Applied transcranially in small PBM pilot trials to support parasympathetic activation.

Which Hz for which goal.

A starting map for common intents — matched to the research in Section 2 above. Not a protocol prescription. A place to begin.

This is a starting map, not a prescription. Individual response varies by condition, age, tissue type, and goal. Pair with practitioner guidance for serious conditions. Most protocols compound over 4–12 weeks of consistent use.
