Summary: Exposure to long-wavelength red light significantly reduced blood clot formation in both mice and human studies. Red light was associated with lower inflammation, reduced immune system activation, and fewer clot-promoting mechanisms, such as neutrophil extracellular traps (NETs) and platelet activation.
Unlike blue or white light, red light influenced clotting through optic pathways, suggesting its effects are mediated by neural mechanisms rather than direct blood exposure. These findings offer promising implications for reducing risks of heart attacks, strokes, and other clot-related conditions, particularly in high-risk groups like cancer patients.
Researchers are developing red-light-based interventions, such as goggles, to explore potential therapeutic applications. If verified through clinical trials, this…
