Red Light Therapy and Testosterone: Do At-Home Panels Boost Levels?
Truth Rating
Claims that red light therapy or 'testicular sunning' can increase testosterone by 200% are based on misinterpreted 1930s data and animal studies; modern human consensus finds no robust evidence for such a clinical effect.

🔥Hot Take:
- Shining red light on your testicles is essentially a high-tech placebo for hormones; while it likely won't hurt you if kept cool, your '200% boost' is a 1939 ghost story.
- The 200% statistic originates from an 85-year-old study on UV light (which causes cancer), not the red LED light used in modern biohacking panels.

Claim Breakdown:
📝 Fact Check: The '200%' figure is frequently cited in biohacking circles but is traced back to a 1939 study by Myerson et al. that used UV light (ultraviolet), not red light or near-infrared (NIR). While modern animal studies (rats) show some increase in testosterone via Leydig cell stimulation, robust human clinical trials have failed to replicate a 200% increase or even show consistent significant gains in healthy males.
