How Infrared Therapy Boosts Circulation, Cellular Repair, and Detoxification

Infrared therapy stimulates the body’s circulatory system by increasing heart rate and expanding (vasodilating) blood vessels and capillaries. This improved circulation flushes the vascular system — arteries, venules, and vessels — and helps deliver more oxygen-rich blood to tissues throughout the body.

Better blood flow promotes detoxification by moving toxins from fat (adipose) cells to the skin’s surface for removal through sweat. This process not only improves cellular health, but also enhances muscle recovery, strengthens immune response, and supports whole-body healing.

NASA-backed evidence confirms what sauna users already feel:

In the study “NASA Light Emitting Diode (LED) Medical Program – Progress in Space Flight and Terrestrial Applications,” researchers found that near infrared light absorbed by cells helped stimulate metabolism in muscle, bone, skin, and subcutaneous tissues — leading to accelerated wound healing and tissue regeneration.

Even more compelling, NASA’s research found that near infrared light stimulates the mitochondria — the energy-producing centers of every cell — by activating color-sensitive proteins called chromophores (particularly the cytochrome system). This cellular activation results in more efficient energy production and repair at the cellular level.

The bottom line:

Near infrared therapy doesn’t just make you feel better — it works on a cellular level to restore energy, improve blood flow, and help the body heal faster.
