It is orchestrated to feel more comfortable indoors, because sunshine produces vitamin D naturally which helps with mental stability, immune health, and energy. Fresh air (with natural allergens such as pollen) helps build immunity or tolerance to local bacteria and allergens and it’s easier to control a population when they are indoors… but those are just my thoughts… and in my opinion it’s working… now a days on a beautiful snowy day… I rarely see kids playing outside in it, more people have empty boring yards and less gardens growing their own food… my wife is doing a homeschool initiative called 1000 hours outside to get kids outside for at least 1000 hours a year because kids average less than half that these days and at least 1200 hours in front of a screen instead.
