LED Light Therapy

A full-body LED Light Sauna session using NASA-developed red and near-infrared light technology. The session delivers therapeutic wavelengths that penetrate skin and tissue to interact with mitochondria, supporting cellular energy production and collagen synthesis. The treatment is non-invasive, generates no heat discomfort, and requires no downtime. Protective eye shields are provided.

Cryo Tokyo's LED Light Sauna delivers a full-body photobiomodulation session using technology originally developed by NASA for plant growth experiments aboard the Space Shuttle and later adapted for wound healing research. The system emits red light in the 630 to 660 nanometre range alongside near-infrared light at 810 to 850 nanometres, covering the two wavelength windows most studied for biological effects. Red light at these wavelengths penetrates the skin to a depth of roughly 8 to 10 millimetres, primarily influencing fibroblast activity and collagen production. Near-infrared wavelengths reach deeper into muscle, tendon, and joint tissue. At the cellular level, photons are absorbed by cytochrome c oxidase in the mitochondrial electron transport chain, increasing adenosine triphosphate output and reducing reactive oxygen species. This cascade supports cellular repair, lowers localised inflammation, and promotes tissue regeneration. The LED Light Sauna at Cryo Tokyo surrounds the body uniformly, unlike handheld panels that treat only a localised area. Clients lie inside the pod wearing minimal clothing for maximum light absorption. The session lasts approximately 30 minutes. No ultraviolet wavelengths are emitted, so there is no tanning or burning risk. Protective eye shields are provided and should be worn throughout. Regular users often report improvements in skin tone and texture, reduced appearance of fine lines, faster resolution of minor wounds or blemishes, and a general sense of relaxation after sessions. Athletes at Cryo Tokyo frequently pair the LED Light Sauna with cryotherapy — the cold exposure targets systemic inflammation while the light therapy supports cellular repair and collagen maintenance. Cryo Tokyo recommends two to three sessions per week for skin and recovery goals. The treatment is suitable for all skin types and requires no preparation beyond removing lotions or sunscreen that could reflect or absorb the light before it reaches the skin.
