Embrace the Sun: UVA and UVB's Hidden Benefits

UV light, particularly UVA, plays a crucial role in human health, as evidenced by the presence of natural detectors for it in our skin and eyes. This evolutionary feature hints at its importance. UVB light is vital for stimulating high levels of vitamin D and POMC, which are essential for overall health. The argument against UV exposure often overlooks the fact that most research has only examined UV light in isolation, ignoring the majority of sunlight that consists of red and infrared wavelengths. These longer wavelengths not only mitigate the harmful effects of UV light but also reduce inflammation and DNA damage. Thus, the negative perception of UV light lacks a solid foundation when considering biological interactions and the broader spectrum of sunlight.
