This is exactly what I've been thinking about lately. The modern knowledge-worker lifestyle is practically an experiment in extreme sun deprivation. We optimize our indoor spaces with perfect AC, ergonomic setups, and even custom ambient noise apps just to stay locked in a room for 10 hours a day doing deep work.
It makes you wonder how much of what we accept as "normal" afternoon brain fog or tech burnout is actually just our biology reacting to this massive behavioral shift and lack of natural light.
