285 Hz is the second of the extended Solfeggio frequencies, sitting between the foundation tone (174 Hz) and the original six-note scale beginning at 396 Hz. It is known as the "Healing Frequency" for its purported ability to support the body's natural repair processes at a cellular level.

Sound therapists associate 285 Hz with wound healing, tissue regeneration, and the restoration of organs to their optimal state. It is often used in recovery settings — after surgery, injury, or illness — as a complementary support alongside conventional treatment. The frequency is believed to send signals to the body that encourage it to restructure and heal damaged tissue.

The tone has a warm, nurturing quality that many listeners find deeply comforting. It is gentle enough for extended listening sessions and works well as a base frequency in multi-tone healing compositions, often paired with 174 Hz below and 396 Hz above to create a progressive healing journey.
