Explore the science of photobiomodulation (PBM) and red light therapy. Learn if whole-body light beds actually improve exercise recovery and athletic performance.
Best quote from Red Light and the Molecular Brake: Photobiomodulation Facts
Biohacking isn’t just about adding new things like light therapy; it might be about removing the internal constraints, like molecular brakes, that are holding us back.

The science behind bio hacking and what actually works.
Frequently Asked Questions
Photobiomodulation, often referred to as PBM or red light therapy, is a field of study focused on using specific wavelengths of red or near-infrared light to trigger cellular changes. While it is often marketed as a biohacking tool for sharpening the brain and improving sleep, the core concept involves using light to influence biological processes. Despite its futuristic reputation, researchers are still working to determine how these light wavelengths translate into measurable health benefits.
According to a major review published in January 2025, whole-body photobiomodulation beds did not show clear benefits for exercise performance or recovery. After screening nearly two hundred studies, researchers found that these high-tech light beds didn't perform significantly better than doing nothing at all. While the marketing suggests they are essential for athletes, the current data indicates that the promise of this specific biohack may be hitting a brick wall.
While red light therapy and near-infrared light are popular in the biohacking community, the shiny marketing often outpaces actual lab results. Influencers may claim it acts as a fountain of youth for muscles and brain health, but scientific reviews suggest a more cautious approach. As discussed in Red Light and the Molecular Brake, the evidence for whole-body PBM providing a competitive edge in athletic recovery remains inconclusive based on recent 2025 data.
