Carbon Dioxide has long been used as an indicator of good indoor air quality primarily because of its association with ventilation. When carbon dioxide levels are high, it may indicate that your space is not well ventilated. The ideal level of CO2 is needed to reduce the risk of lung inflammation6.
Chronic inflammation caused by persistent high CO2 levels is not ideal for your health. Moreover, longer exposure to high CO2 can cause fatigue,
headaches, and dizziness. It is also possible to develop hypercapnia acidosis6, characterized by increased levels of carbon dioxide in the blood. This suppresses immune function and can make one more susceptible to disease.
Some causes of carbon dioxide elevation indoors: improperly maintained combustion devices and poor ventilation.
