Carbon dioxide (CO2) is a naturally occurring greenhouse gas, but humans are responsible for pumping unhealthy levels of it into the atmosphere. People have accelerated the release of CO2 through the burning of fossil fuels like gasoline, oil, and natural gas. We also release CO2 naturally when we exhale.
For a long time, it was believed that CO2 levels had little effect on people, but there is a growing body of research suggesting that CO2 found in classrooms and bedrooms may have a harmful effect on the body, including cognitive abilities.
CO2 is a primary greenhouse gas that is naturally released from volcanic activity, wildfires, and decomposition. The earth’s carbon cycle controls levels of CO2 through a natural process involving the oceans, soil, plants, and animals.
However, humans are pumping more carbon dioxide into the atmosphere than the earth can absorb. With the burning of fossil fuels, deforestation, and cement production, humans release gigatons of carbon dioxide each year, only part of which the earth removes. This overflow has increased atmospheric concentrations of carbon dioxide from 330 ppm in 1975 to well over 400 ppm in 2017.
CO2 & Climate Change
Because CO2 is a greenhouse gas, carbon dioxide is a contributing factor to global climate change. Even though the world’s climate is constantly in flux, the increase in human emissions has created a global warming trend and an increase in the occurrence of extreme weather events. The Natural Resources Defense Council reports that climate change is to blame for more heat-related deaths and the spread of infectious diseases.
The National Institutes of Health says the rise of CO2 levels has coincided with a sharp increase in asthma cases across the globe due to its link to climate change, and the Harvard Medical School and the Center for Health and Global Environment links the rise in asthma cases, in part, to climate-related factors like CO2 emissions. The study found a sharp increase in asthma cases among preschoolers from 1980-1994. The 160% jump was tied to the rise in CO2 and the impact on air pollution and climate change.
CO2 in Your Home
Climate change is not the only way carbon dioxide can harm you and your family. It can also directly cause cognitive problems when exposed to moderate to high levels indoors.
At levels commonly found in schools and meeting rooms, kids can experiences issues with focus related to the CO2 in the room. They may find it difficult to concentrate, and their head could feel foggy. Not only that, but your kids can also feel sleepy or tired when exposed to this CO2. They will not perform or feel their best at school or home breathing in extra carbon dioxide.
How Can I Protect My Child from CO2?
Your air purifier will not filter out carbon dioxide, and an air mask will not help, either. The only way to deal with in-home carbon dioxide is to dilute it with fresh, outdoor air. The best way to dilute your air is through manual or mechanical ventilation.
Even if it is just opening a window, letting fresh air into your home will help prevent carbon dioxide from building up. Keeping the door open while your children sleep will help protect them at night. For a more permanent fix, make sure that your HVAC system is in good working condition and that the ventilation system in your home is pulling in enough fresh air from outside.
Remove sources of CO2
Common sources of CO2 in your home are fireplaces, stoves, cigarettes, and candles. Anything with an open flame creates carbon dioxide. Removing these sources of dangerous CO2 will help limit how much CO2 your kids are exposed to.
Know your air with a CO2 monitor
While ventilation and removing open flames will definitely help protect your child, carbon dioxide could be there without you knowing it. CO2 is a colorless, odorless gas. You won’t be able to detect it on your own. The only way to know for sure how much CO2 is in the room is by getting a carbon dioxide monitor.
The Laser Egg+ CO2 is an indoor air quality monitor designed to help you take action when the air in your home goes south. The Laser Egg can work with your smart home appliances to automatically run an air purify or air conditioner to improve air quality. The easy-to-read screen uses colors and the standard air quality index (AQI) number system to keep you informed. The Laser Egg is portable and is easily moved from room to room. You can also take it with you in the car or on family trips. All you need is a WiFi connection. Learn about the Laser Egg products by clicking here.
