Lately, our whole team has been feeling drowsy in the afternoons. The air in our office feels heavy, even though the HVAC system is running. We’ve started wondering if indoor air quality is to blame. Has anyone tracked this somehow, or is it just in our heads?
I worked in an office where fatigue and even headaches became regular by 2 PM. We decided to test the theory using real-time indoor air quality monitors, and the data shocked us. CO₂ levels were peaking right after lunch, reducing alertness. Once we saw the numbers, it was easier to get management to improve ventilation and add some purifiers. Within a week, the difference was obvious — people were more awake, meetings went smoother, and the general vibe improved. It's a smart move if you're noticing energy dips at the same time daily.
