Indoor CO2 concentration. Main Reasons To Monitor CO2 Levels

Have you ever felt stuffy or sleepy in a room? It might be because of high CO2 levels. Carbon dioxide (CO2) is a normal part of the air we breathe, but in closed spaces with poor ventilation, it can gather quickly. With people spending up to 90% of their time indoors, it’s more important than ever to ensure the air we breathe is safe and clean.

High CO2 levels can cause discomfort, lower concentration, and even health problems. This is especially important in places like offices, schools, and homes where we spend a lot of time.

Poor ventilation can make CO2 levels rise even faster. Monitoring indoor CO2 levels helps keep the air quality good, making sure you stay healthy and productive.

Let’s explore why keeping an eye on CO2 is so important and how it can improve your daily life.

Why Measuring CO2 Levels Matters for Your Health

Ever wondered why you feel tired and unfocused in a stuffy room? It might be the high CO2 levels affecting your brain. Monitoring CO2 isn’t just about air quality – it’s about your health and productivity. Keep reading to find out how CO2 levels impact your daily life and why it’s important to keep them in check. 

• Health Effects: High levels of CO2 can cause headaches, dizziness, and tiredness. In some cases, it can lead to respiratory problems and even affect your cognitive function. Studies show that cognitive performance can drop significantly when CO2 levels rise. For example, at levels around 1,000 ppm, people often lose focus and productivity​ (Penn Today). 

• Cognitive Impact: HighCO2 levels directly affect how well you think. Research from Harvard found that cognitive scores decrease by 21% when CO2 levels reach 945 ppm compared to 550 ppm. This means slower response times and less accurate decision-making​ (Harvard School of Public Health). 

• Productivity: Offices and schools with high CO2 levels see reduced productivity and performance. For every 500 ppm increase in CO2, response times slow down by 1.4-1.8%, and cognitive throughput drops by 2.1-2.4%. KeepingCO2 levels low can boost work efficiency and learning. ​ (Harvard School of Public Health). 

• Long-Term Exposure: Being around high CO2 levels for a long time can make chronic health issues worse. The WHO recommends keeping indoor CO2 levels below 1,000 ppm to avoid long-term health risks​ (Penn Today). 

• Ventilation and Air Quality: Monitoring CO2 levels helps find areas with poor ventilation. Good ventilation reduces CO2 buildup and improves overall air quality, which is essential for a healthy indoor environment. This is especially important in crowded spaces like schools, offices, and public buildings​ (Penn Today). 

• Future Projections: As outdoor CO2 levels rise, indoor levels will too by the end of the century, indoor CO2 levels could reach up to 1,400 ppm if current trends continue. At these levels, cognitive function could drop significantly, with decision-making abilities potentially decreasing by 25% and complex strategic thinking by 50%​ (Penn Today). 

Monitoring CO2 levels isn’t just a technical necessity – it’s a vital aspect of maintaining a healthy and productive environment.  

Typical CO2 Levels in Offices and Indoor Spaces

CO2 levels in indoor space can change on the number of people, the ventilation system, and the activities going on. Here are some typical ranges and their effects: 

Well-Ventilated Spaces (400-1,000 ppm): Modern offices and well-maintained public spaces with efficient HVAC systems. 

• Health Impact: Generally safe, with minimal or no health effects. These levels are close to the typical outdoor concentrations. 

Moderately Ventilated Spaces (1,000-2,000 ppm): Environments with moderate ventilation, such as older office buildings or classrooms with poor airflow. 

• Health Impact: Long exposure can cause headaches, sleepiness, and lower thinking ability. According to a study from Harvard, for every 500 ppm increase in CO2, response times can slow by 1.4-1.8%, and cognitive throughput can drop by 2.1-2.4%​ (Harvard School of Public Health)​. 

Poorly Ventilated Spaces (2,000-5,000 ppm): Crowded areas with bad ventilation, such as packed meeting rooms or poorly maintained indoor spaces. 

• Health Impact: High levels can lead to significant discomfort, including dizziness, headaches, and impaired cognitive function. Long-term exposure at these levels can increase the risk of chronic health issues​. 

Extremely Poor Ventilation (>5,000 ppm): Rarely found in most office settings but possible in extremely confined or overcrowded areas without any ventilation. 

• Health Impact: At this level, CO2 can cause serious health issues, including unconsciousness and long-term breathing problems. Such conditions are dangerous and require immediate intervention. 

Did you know that improving indoor air quality can double cognitive performance? This fact highlights how even small changes in air quality can significantly boost decision-making and problem-solving abilities.  

Regular monitoring of CO2 levels helps identify areas with poor ventilation, allowing for timely interventions to improve air quality. Using CO2 sensors and integrating them into HVAC systems can help manage ventilation more effectively, ensuring that indoor environments remain within safe and comfortable CO2 concentration ranges. 

By keeping optimal CO2 levels, we can create healthier, more productive indoor environments that benefit both individuals and organizations. 

How to Control CO2 Levels in Indoor Areas

Creating a comfortable and healthy indoor environment starts with managing CO2 levels effectively. Imagine feeling more focused and energized just by improving your indoor air quality.  Here are some practical and innovative tips to help you maintain optimal indoor air quality.  

• Use Advanced Ventilation Systems: Integrate high-quality HVAC systems to ensure continuous and efficient airflow. Regular maintenance and filter changes are key to keeping these systems operating well. 
• Deploy IoT CO2 Sensors: IoT sensors provide real-time data on CO2 levels, enabling you to make quick adjustments to ventilation and airflow. These sensors can be integrated into smart building systems for automated responses, ensuring consistent air quality. 
• Increase Natural Ventilation: Whenever possible, open windows and doors to allow fresh air to circulate. This simple step can significantly reduce indoor CO2 levels, especially during peak occupancy times. 
• Incorporate Indoor Plants: Plants naturally absorb CO2 and release oxygen, improving air quality. Consider adding a variety of indoor plants or even installing green walls to enhance your environment aesthetically and functionally. 
• Optimize Space Usage: Plan your indoor spaces to avoid overcrowding. Use flexible work arrangements to reduce the number of occupants at any given time, helping to maintain lower CO2 levels. 
• Regular Air Quality Assessments: Perform routine air quality checks to monitor CO2 levels and other pollutants. Use the data collected to make informed decisions about ventilation and air purification needs.
