How Bad Air Affects Your Brain and Productivity

Have you noticed that some days you feel tired, unfocused, and unmotivated — even though you slept enough? The cause might be the air you’re breathing. The latest scientific studies have discovered direct links between indoor air quality and brain function.

CO₂ and Cognitive Decline: The Numbers Speak

The renowned COGfx Study from Harvard University revealed shocking results: in well-ventilated rooms, participants’ cognitive performance was 101% higher compared to standard rooms. Crisis response improved by 131%, information processing by 299%, and strategic ability by 288%.

On the other hand, when CO₂ levels reach 1,400 ppm — which commonly happens in closed offices and classrooms — cognitive performance drops by 50%. At 2,500 ppm, 7 out of 9 decision-making abilities are severely impaired.

Schools: Where Bad Air Does the Most Damage

Studies show that doubling the ventilation rate in schools leads to a 14% increase in overall student performance. Math scores rise by 11 points, reading comprehension improves by 7.4%, and task completion speed increases by 8%.

Unfortunately, over 80% of naturally ventilated classrooms exceed the 1,000 ppm CO₂ threshold. This means your children may be learning under conditions that reduce their mental ability.

The Workplace: The Hidden Cost of Bad Air

For every 500 ppm increase in CO₂, employee reaction time slows by 1.4-1.8% and throughput drops by 2.1-2.4%. But the biggest cost doesn’t come from absences — presenteeism (the worker is at the desk but not productive) costs 3 to 10 times more than absenteeism.

Studies show that investing in a ventilation system for 10 employees can pay for itself within 2 months, with an ROI exceeding 500% in the first year. Per employee, the annual savings are estimated at approximately €1,981.

Smart Control: Technology at Your Service

Modern ventilation systems use CO₂, humidity, and PM2.5 sensors to automatically adjust airflow. When CO₂ levels rise, the system increases ventilation. When levels drop, the system slows down to save energy. Everything happens without your intervention. With wall panels or the mobile app, you can monitor air quality in real time.

Invest in Better Air, Invest in Productivity

Clean air is not just a health issue — it’s an investment in performance, well-being, and productivity. Whether for your office, school, or home, a smart ventilation system can make the difference. Contact us to discuss the best solution for your space.
