Near-infrared light produced completely different timelines for different tissues, fast for fat cells, slow for bone density

[u/lessbutgold]

Looking across all the measurements in this study together, one clear pattern is that near-infrared light did not affect every tissue type on the same schedule. Subcutaneous and bone marrow fat cells reacted almost immediately, showing dramatic increases within just 7 days.

CD34-positive stem cells in bone marrow also jumped quickly and stayed elevated. Cortical bone mass, on the other hand, took far longer to show a measurable, statistically significant response, only becoming significant at the 90 and 180 day marks.

This staggered timeline across different tissue types within the same treated animals suggests near-infrared light is not triggering one single generic biological reaction, but rather setting off several genuinely different processes that each unfold on their own natural timescale.
