Red light therapy appears to produce measurable improvements in recovery metrics—lactate levels have been observed to return to baseline within 15 minutes of red light therapy bed use post-workout—providing objective evidence that red light therapy affects athletic recovery physiology measurably and quickly.

Dom D'Agostino (neuropharmacologist and researcher) is very interested in lactate's effects on brain function and specifically studies lactate levels in different contexts (baseline, pre-workout, post-workout) because of this neurological interest, making him particularly interested in how red light therapy affects lactate levels quickly.

Ability to return to baseline metabolic state quickly after intense exercise is 'a really good marker of how huge marker truly athletic you are'—athletes who remain chronically stressed and elevated for hours post-workout versus those who complete effort and normalize represent fundamentally different athletic capacity or physiological efficiency.

Red light therapy beds have been expensive enough historically that Brealey rigged a portable device to hover over their face on two chairs, but expressed concern about dogs knocking it down, illustrating the practical challenges of trying to DIY professional-grade red light therapy setups at home.

Dom D'Agostino is described as 'a brick house' on Instagram who behind-the-neck shoulder presses 285 pounds for reps at approximately 200 pounds bodyweight, demonstrating that high athletic performance is compatible with keto diet and careful supplementation, despite stereotypes about keto and athletic performance.
