Red light therapy (RLT), also called photobiomodulation, uses low-level red and near-infrared (NIR) light to stimulate cellular processes. It’s non‑thermal (doesn’t heat tissue) and is applied with LEDs or low‑power lasers.

Red (about 630–700 nm) and NIR (about 800–1100 nm) light penetrates skin and is absorbed by cellular chromophores (notably mitochondrial cytochrome c oxidase).

This can increase mitochondrial ATP production, reduce oxidative stress, and modulate inflammation and signaling pathways.

Vibroacoustic therapy (VAT) uses low-frequency sound vibrations to produce tactile (vibratory) and auditory stimulation to the body. It’s used for relaxation, pain management, stress reduction, muscle tension, and sometimes for neurological or respiratory symptoms.

Molecular hydrogen therapy uses molecular hydrogen gas (H2) as a wellness intervention, It’s proposed to act as a selective antioxidant and signaling modulator with potential benefits for inflammation, oxidative stress, and cellular injury.
