Sunlight exposure is associated with reduced all-cause mortality, as well as reduced incidence of several specific diseases including some types of cancer.
It’s also associated with higher endorphin levels, and the maintenance of proper circadian rhythm through melatonin synthesis.
Most of these effects have been found to be unrelated to vitamin D, but that’s also a significant benefit considering the poor bioavailability of supplements.
The reduction in all-cause mortality from sunlight exposure is significant enough that people with an early diagnosis and treatment of non-melanoma skin cancer have a higher average life expectancy than the general population.
I've always assumed that those results are caused by exercise, and since many people exercise outdoors, being outdoors more is correlated with better health, but the better health is actually caused by by the exercise, not the being outdoors. As for the circadian rhythm, SAS should embrace More Dakka [0] and cover his entire ceiling in bright white LED modules. He has Substack money to spend after all. I thought D3 was pretty good with absorption, though he could start drinking milk and take GLP-1 inhibitors to offset that if needed.
