Effect of Green Plants on Near-Impa-Red Light Exposure Outdoors

The presence of green plants outdoors significantly increases the amount of near-impa-red light that the body is exposed to. Plants have a high reflectivity in the near-impa-red spectrum, leading to a shift in the light spectrum that we experience outdoors. Additionally, dirt also reflects near-impa-red light more than visible light. This combination results in a situation where the body is consistently exposed to near-impa-red light along with visible light when outdoors, impacting the body's biological functions, especially mitochondrial function. Unlike the outdoor environment, indoor settings lack sufficient near-impa-red light, creating an imbalance in light exposure. Children, due to their smaller size, are more affected by near-impa-red light exposure than adults. Restricting children from outdoor play deprives them of the beneficial effects of near-impa-red light that the body naturally expects from sunlight exposure. The artificial indoor environment, devoid of adequate near-impa-red light, contrasts with the natural outdoor setting, leading to a significant reduction in overall solar exposure historically, impacting human health negatively.
