No More Tired Lungs: Understand What’s Toxic For Our Little Ones.
Estimated Reading Time: 5 Minutes.
Why are children feeling down, cranky, and getting sick so often? Keep an eye on the air; these harmful pollutants might be the major factor.
As we all know, kids tend to hang out in the fresh air to explore their surroundings in the world. Most of the time, their bodies are still figuring out the proper ways to fight off germs. However, the places where they spent a lot of time interacting with their little lungs are mainly exposed to the floor level (which is normal for their height). Where they crawl, lie down, take a quick nap, and play is undoubtedly filled with harmful airborne pollutants like particulate matter (PM2.5 and PM10) that could interfere with their respiratory development.
It is a concerning matter. That’s why various world-renowned air quality assessment organizations like WELL, LEED, and RESET are constantly pushing to highlight the importance of regularly checking key indoor air quality (IAQ) in childcare settings.
The Invisible Enemy To Clean Air
Picture this. Behind every bright classroom filled with colorful toys and cheerful ambience, there is a chance the air isn’t as clean as it looks; each breath of air may contain poor quality that harms the immune and respiratory systems of our beloved little ones. A study published by the Center on the Developing Child at Harvard University (Air Quality Affects Early Childhood Development and Health) implies that air pollution hits kids hard; although the risks aren’t just immediate, they stick around because their immune systems are still developing, hence vulnerable, while they breathe in more air relative to their body weight.
Children under five breathe faster and are usually more physically active, spending up to 90% of their time indoors. Different from adults, these young bodies haven’t built up strong antibodies to safeguard against invisible dangers. Honestly, adults feel sluggish, heavy, or somewhat irritated too when the air goes stale, but children often feel these effects more intensely. This can show up as reduced attention spans, fatigue caused by illnesses, disrupted sleeping patterns, and even slower cognitive development.
With that being said, air pollution significantly threatens their health, leading to immediate and long-term effects, making life harder both now and later. Consequently, Indoor Air Quality (IAQ) should be monitored and managed to ensure the air they breathe daily supports their well-being and promotes positive learning outcomes. Spaces filled with children can silently gather pollutants like VOCs, dust, humidity imbalances, and abnormal CO₂ levels without obvious warning signs, making ongoing IAQ monitoring essential to protect them.
In a nutshell, parents and caregivers could ensure clean, breathable air as a priority that is within your reach. Together, we can advocate for better air quality in education.
Five Critical IAQ Parameters You Ought To Know
- Carbon dioxide (CO₂):
We often recognize CO₂ as the long-lived greenhouse gas that heats the planet. But did you know how CO₂ really affects children? CO₂ levels often serve as a key indicator of ventilation quality. Abnormal levels can lead to noticeable symptoms of rapid breathing, a weak body, throbbing headaches, reduced focus, and behavioral issues. Researchers suggest extra precautions are recommended when aerosol-emitting activities such as high-intensity exercise, singing, and prolonged speech (including teaching) take place; childcare guidelines should ensure that CO₂ levels stay below 800 ppm, which is stricter than office standards. - Total Volatile Organic Compounds (TVOCs):
Known as a variety of chemicals released as gases from common man-made products such as paints, cleaners, diapers, detergents, and plastics. These high concentrations of toxins will be a hazardous threat to children. Overexposure may lead to discomfort in the eyes, nose, and throat, increasing allergies and nasal sinus congestion. Long periods of exposure raise the risk of chronic respiratory illnesses, such as asthma and bronchitis. - Formaldehyde (HCHO) Risks:
Quietly, it lurks in the dark; common sources and everyday items that toddlers handle, such as furniture, flooring, mattresses, adhesives, and new toys, can expose them to formaldehyde irritation, causing difficulty in breathing and a burning sensation in the throat. The worst scenario is that it’s a known human carcinogen linked to leukemia. Therefore, WELL provides guidelines for using low-emission materials and requires post-occupancy IAQ testing, while Aeropulse’s air monitoring solutions are compatible with a range of interchangeable modular capsules that detects HCHO with ease. - Particulate Matter (PM2.5 and PM10):
The smaller they are, the more hazardous they become. These microscopic particle pollutions are formed by complex chemical reactions of industrial processes and biomass burning, including bacteria and mold spores that are difficult to detect with human eyesight. Increasing levels of PM10 can lead to upper respiratory irritation, triggering conditions like asthma or bronchitis, while PM2.5 can cause severe issues like cardiovascular disease. - Temperature and Humidity Balance:
Climate change has been proven to pose threatening risks towards the well-being of young children, which can cause mild symptoms such as sweating, dizziness, nausea, and severe muscle cramps. Studies show that ideal indoor humidity should stay between 40% and 60%. Whether dry or moist, the disrupted balance of humidity will accumulate the risk of mold growth, resulting in airway irritation, flu, and persistent nighttime coughing that doesn’t seem to go away.
Project Fresh Air: Embrace New Changes with Aeropulse.
Located in Shanghai, a bilingual childcare center serving children aged two to five faced issues with afternoon fatigue and poor nap quality. Educators noticed ‘stuffy air’ during learning sessions and tried various solutions but couldn’t figure out why. That’s when the Aeronode Series, specifically the A100 and A200 (view A100 – Aeropulse and A200-CO2 – Aeropulse), came in to address the problem by monitoring the air quality right away.
For the first 14 days, the center installed advanced monitoring devices in eight classrooms and nap rooms where children spent most of their time. These sensors logged and collected multiple parameters. It turns out to reveal high CO₂ levels shooting up to 1,300 ppm in the afternoons due to closed doors and a significant 35% drop in humidity in winter, making it easier for bacteria to spread, which is linked to coughing. TVOC levels spiked in one classroom after some newly delivered furniture, setting off timely alerts to the teachers via the cloud dashboard.
Soon, they managed to act fast by scheduling multiple ventilation adjustments to improve air circulation and ensuring continuous airflow. They installed door vents, moved VOC-emitting items away from children’s reach, and brought in suitable humidifiers to maintain ideal humidity levels, solving bottlenecks and inefficiencies in operational decisions.
Eventually, things got better; positive responses became evident after 56 days of using Aeropulse’s A100 and A200 series. Average CO₂ levels dropped from 1,420 ppm to 820 ppm, ensuring a safe environment where children could sleep soundly, surrounded by clean air. To raise awareness about clean air quality, real-time IAQ data from the dashboard is displayed at the entrance. With healthier air quality and happier laughter. It proves that clean air should always be a priority wherever our kids spend their days.
