Damn, that’s wild—Harvard stuck 24 office workers in the same room for 6 days, secretly tweaking the air quality (ventilation, CO2, and VOCs from typical office stuff), and their cognitive scores doubled in the cleaner “green+” conditions vs. standard stale setups. Better decision-making, strategy, crisis response—all crushed by poor indoor air we breathe 90% of the time. Open windows, crank ventilation, cut the junk emitters. Your brain’s paying the price right now. Fix the air, sharpen the mind.
