Red light therapy gives muscles a small, real boost
Shining low-level light on muscles modestly improved endurance and strength across 23 pooled trials in healthy people, with athletes seeing the clearest endurance gains. Nobody yet knows which dose, timing or device settings work best.
For you: Worth knowing light therapy may add a small edge to muscle performance, but with the recipe still unsettled there is no reason to buy a specific device on the strength of this.
What it shows: Real but small: results pooled from 23 trials in healthy people show only a modest edge, and the best dose, timing and settings are still unknown. The subgroup patterns are exploratory, so treat any specific device protocol claim with caution.Review · J Integr Complement Med
