The Science Behind Light Therapy: Proven by NASA Research

In recent years, red light therapy (RLT) has become a major trend in skincare, wellness, and sports recovery. But is it truly backed by science?

The answer is yes—and the origins of this technology can be traced back to NASA’s groundbreaking research in the 1990s.

1. How NASA Discovered the Power of Light

During long-duration space missions, NASA scientists sought ways to accelerate wound healing and tissue regeneration in astronauts who might be injured in space.

Their experiments using red (660nm) and near-infrared (850nm) LED light revealed remarkable results:

• Cell growth increased by 150% to 200%;

• Mitochondrial activity and ATP production surged;

• Tissue repair and inflammation recovery improved significantly.

These discoveries became the scientific foundation of red light therapy, inspiring decades of clinical and commercial development for infrared healing technology.

2. The Biological Mechanism Behind NASA’s Findings

NASA’s studies showed that light therapy works at the cellular level.

When red or near-infrared photons are absorbed by cytochrome c oxidase within the mitochondria, the cell’s energy metabolism increases.

This boost enhances cell regeneration, anti-inflammatory response, and tissue repair—explaining why light therapy benefits both the skin and muscles.

3. From Space Labs to Everyday Life

NASA’s LED research inspired medical and consumer device innovation. Today, red light therapy is widely used for:

Skincare & Anti-Aging

Pain Relief & Muscle Recovery

Wound Healing & Nerve Repair

Note: YEEQO’s home LED therapy devices are designed with NASA-backed wavelengths (660nm & 850nm) to deliver safe, effective results in your daily wellness routine.

4. Conclusion: NASA Proved the Science, We Brought It Home

NASA’s research provided the scientific validation that red and infrared light can enhance cellular energy and healing.

Far from a beauty fad, red light therapy is an evidence-based, non-invasive technology supported by decades of studies and clinical trials.

Thanks to modern LED innovation, what began as NASA’s space experiment is now part of everyday health and self-care.
