We have indeed learned amazing things about melatonin and light exposure and iprgcs over the last four decades, and I think that's very important, too. So I'm glad you've mentioned it: a natural night with extremely consistent start and stop times (or following the seasons strictly, which is better) absolute darkness (except red light is okay) and nine hours of it is a very good thing for health - mental and physical. But yup, I meant melanin, the more recent outpouring of research there is amazing. Melatonin is an amazing antioxidant, just amazing, and as a hormone it initiates processes that fight illness at night, including pathogens, but I don't know of it having any direct action against pathogens.
