Outdoor CO2 levels are frequently as low as 400 ppm, whereas interior CO2 levels typically vary from 420 to 1000 ppm. CO2 values under 1000 ppm are considered healthy levels. The best way is to open all the windows of classroom.
What are the health risk of high CO₂ level?
- People may have moderate symptoms like sleepiness, restlessness, an accelerated heart rate, and breathing difficulties if levels exceed 1000 ppm.
- This is particularly problematic in educational settings when learning new material calls for increased focus and attention from students.
- In addition to causing significant discomfort, levels of CO2 above 2000 ppm prevent pupils from functioning at their best in class and, over time, impair the growth of their cognitive abilities.
- In addition to the above described symptoms, there are others including nausea, poor focus, and feeling stifled.
- Indoor CO2 levels are normally below 1000 ppm, but if there are more than 20 pupils and teachers in a closed space, the CO2 levels will naturally rise, and it is not unusual for them to exceed 3000 ppm.
