Photobiomodulation therapy (red/NIR LEDs) reduced the length of stay in intensive care unit and improved muscle function

Despite my best intentions, I typically spend less time in the sun during the colder winter. Is it worth the effort?
Methods: This randomized, triple-blind, sham-controlled trial was conducted in a hospital ICU.
Sixty patients were randomly assigned to two equal groups: (a) PBMT and (b) Sham. PBMT was applied daily to patients until their discharge from the ICU, using a flexible neoprene array of 264 LEDs (120 at 635 nm, 1.2 mW each; 144 at 880 nm, 15 mW each) for 90s (207.36 Joules) at each site. Ten sites were located bilaterally on the thighs, legs, arms, and forearms ventrally and dorsally, 15 min totaling 2,073.6 Joules per session. Outcomes were length of stay (in h) until discharge from the ICU, muscle strength by the Medical Research Council (MRC) score and handgrip dynamometry (HGD), patient mobility by Intensive Care Unit Mobility Scale (IMS) and
the Simplified Acute Physiology Score 3 (SAPS 3) for predicting mortality of patients admitted to the ICU.
Results: PBMT reduced the average length of stay in the ICU by ~30% (p = 0.028); increased mobility (IMS: 255% vs. 110% p = 0.007), increased muscle strength (MRC: 12% vs. ā9% p = 0.001) and HGD (34% vs. ā13% p < 0.001), and the SAPS3 score was similar (p > 0.05).
Conclusion: The results suggest that daily PBMT can reduce the length of stay of ICU patients and increase muscle strength and mobility

the thing with red light is wtf is the dose . it is apparently biphasic so too much is as bad as too little. they did 15 min here with lights right up against the skin , probably not very powerful. these niggas are measuring joules. I guess u gotta do some maths and know the intensity of your device at which distance.
