Affects of increased CO2 levels on human health

Exposure to carbon dioxide (CO2) poses direct risks to human health. But, at lower levels than previously thought, research has found.

Reviewing current studies on the subject, American academics concluded new research. That exposure to ambient CO2 in indoor environments can have harmful effects on the human body at much lower levels. Hence, causing health problems. Some of which are inflammation reduced cognitive performance, and kidney and bone problems.

They found these health problems can be caused by exposure to CO2 levels. That can be as low as 1,000 parts per million (ppm). A far lower limit than the 5,000 ppm level that had been widely accepted, researchers said.

The findings are published in the journal Nature Sustainability. They sum up a growing body of research into CO2’s health effects. Which have to date been less explored than the effects of particulate matter (PM2.5) or nitrogen oxide (NOx).

‘This early evidence indicates potential health risks at CO2 exposures as low as 1,000 ppm—a threshold that is already exceeded in many indoor environments with increased room occupancy and reduced building ventilation rates,’ the study summarised.


Researchers have observed CO2 levels over 1,000ppm in poorly ventilated bedrooms and now say acute exposure to this could negatively affect human health.

Those behind the research looked at a total of 18 studies into human exposure to CO2, as well as CO2’s health effects on both humans and animals.

The researchers cited mounting evidence that CO2 levels as low as 1,000ppm can cause health problems, even if people are only exposed to them for an hour or two.

They found that CO2 levels exceeding 1,000ppm have already been observed in crowded and poorly ventilated rooms such as classrooms, offices, and bedrooms as well as air-conditioned public transport and planes – all places where humans can spend several hours at a time. karasu escort

Collating the findings of numerous studies, the academics summarised that acute exposure to high CO2 levels can have ‘adverse health outcomes’, citing studies that observed inflammation and reduced cognitive performance above 1,000ppm. hendek escort

Chronic exposure to levels between 2,000ppm and 3,000ppm can have even worse impacts as this was linked to effects including kidney calcification and bone demineralization.

The team behind the study warned that human CO2 exposure may be a growing problem in the coming years as projections suggest that by 2100 outdoor CO2 levels in some cities could exceed 1,000ppm for parts of the year.

‘Continuous exposure to increased atmospheric CO2 could be an overlooked stressor of the modern and/or future environment,’ the study suggested.

The researchers concluded by saying further research is needed to find ways to mitigate exposure to indoor CO2, especially for children and vulnerable people, and to fully understand its potential health effects.

Why Do We Need to Measure CO2?

High and unmonitored Co2 concentrations can cause headaches, nausea, dizziness, and a stinging sensation. Higher amounts can cause breathing difficulties (shortness of breath), perspiration, tiredness, vomiting, or increased heart rate. At extremely high Co2 levels, it may lead to unconsciousness. 

Though the ambient air contains diluted Co2, this is not evident within a building or in a confined space, such as a restaurant, bedroom, or workplace. This is even worse in populated areas with poor ventilation systems such as schools, banks, and auditoriums. 

Therefore, regular monitoring of carbon dioxide levels is essential to ensure proper and timely management of Co2 levels. Co2 Levels in the outside (or atmospheric) air are approximately 400ppm (parts per million). Humans emit between 35,000 and 50,000 ppm of Co2 into the environment on average. 

If this volume of Co2 remains in a closed space, it can be detrimental to health. Therefore, a Co2 monitor is a piece of essential safety equipment that must be used along with the existing ventilation system. 

Benefits of a Co2 Monitor

  • Improves sleep quality and mental health
  • Balanced Co2 levels help increase cognitive functions
  • Promotes a healthy lifestyle and boosts the immune system
  • Due to poor air quality, sick building syndrome is caused, which is prevented with co2 monitor
  • Reduces Pollution

COVID-19 and Mini Co2 Monitor!

Carbon dioxide levels in buildings are becoming increasingly correlated to the spread of infection through the air. According to recent research, monitoring carbon dioxide levels indoors is an inexpensive and effective way to monitor the risk of people contracting COVID-19. 

As a result, Co2 monitors could serve as a “canary in the coalmine” for coronavirus mitigation. Higher levels of Co2 in a room may lead to an increased possibility of spread of COVID-19 if an infected person is present in the room. Even though balanced Co2 levels do not completely eradicate the risk of COVID-19, it reduces the possibility of transmission as it allows in pointing out the state of ventilation. 

This assessment of air quality has become necessary during a global pandemic. With the help of the Euromate pure air mini Co2 level monitor, you can detect whether your space is poorly ventilated, take necessary actions to improve it, and in turn, reduce the risk of COVID-19 transmission.  sakarya escort

Areas of Application

CO2 monitors can be used in a variety of residential, commercial, and/or industrial settings. Please get in touch with us today to discuss your project.


Measuring Co2 levels is essential. Especially to determine if adequate and healthy ventilation is being provided to the students and the staff. High levels of carbon dioxide have proven to lower students’ performance and cause long-term health problems. Increased carbon dioxide levels also have a direct and unfavorable impact on cognition and decision-making abilities. With the help of Co2 level monitors in schools, these levels can be continuously monitored, and hence, informed decisions can be taken on time.  


On average, people spend around 8 hours daily at work. This could involve a group of people spending several hours in a confined environment. And thus, is subject to increasing CO2 levels. Air quality in an office or work environment must be adequate to ensure good work performance and the workforce’s well-being. A Co2 sensor is easy to place in offices due to its sleek and lightweight design. With offices re-opening after the global pandemic outbreak, it is extremely important to consider the health risks. Especially those that excess carbon dioxide in the atmosphere contains.

It can also be used in dental labs and clinics with a dental air purifier.


Home is where you spend most of your time. And being exposed to a high concentration of carbon dioxide throughout the day is detrimental to your health. In extreme cases, high levels of carbon dioxide in the air can be life-threatening. Thanks to Co2 Sensors and air purifier, now you can measure the atmospheric carbon dioxide levels in real-time without any hassle. erenler escort
