Air pollution is no longer a seasonal crisis in many cities across the country. It is a year-round reality. While we have become used to tracking air quality numbers every morning, we are far less prepared to track what polluted air is doing to the minds of our children. Research across the world now shows that air pollution affects the behaviour of children, their emotions, attention span, and development. Yet most studies look at small samples and short time periods. What we urgently need is continuous, large-scale monitoring of the mental health of children, throughout the year, and in ways that are humane, inclusive, and child friendly.

The question is not whether pollution affects the mental health of children, but how we can understand this impact in real time, across large populations, without stigmatising children. One promising answer lies in art.

What science already tells us

Recent research, including a 2024 study published in Scientific Reports, shows clear links between air pollutants such as nitrogen dioxide (NO), ozone (O), sulphur dioxide (SO), and particulate matter (PM10, PM2.5) and mental health outcomes in children. These include behavioural and developmental disorders, ADHD, anxiety, and eating disorders. Importantly, this study looked at rural children, proving that pollution-related mental health risks are not limited to cities.

Decades of evidence now show that long-term exposure to polluted air affects attention, memory, emotional regulation, impulse control, and anxiety levels in children. These effects often begin early in life, sometimes even before birth, and can quietly shape learning outcomes, behaviour in classrooms, and long-term well-being.

Yet most monitoring systems still rely on hospital data, diagnoses, or short surveys. These methods miss early signals, everyday struggles, and children who never reach clinical thresholds but are still suffering.

Why continuous monitoring matters?

Mental health is not static. A childs anxiety, attention span, or emotional balance can change with seasons, pollution spikes, school stress, or family circumstances. In cities, where pollution peaks in winter but never truly disappears, children are exposed continuously. Monitoring mental health once a year is like measuring air quality once a year; it tells us very little.

Continuous monitoring will help in detecting early changes before they become disorders, understanding cumulative and long-term effects, identifying vulnerable age groups and neighbourhoods and design timely interventions, not delayed responses. However, this monitoring must be ethical, non-invasive, and scalable. This is where art becomes powerful.

Art as a window into children's minds

Children often cannot explain anxiety, confusion, or emotional overload in words. Art gives them another language. Drawing, painting, music, dance, storytelling, theatre, and creative writing allow children to express inner states safely and naturally.

Art reflects mental health in several ways:
Emotional expression: Colours, shapes, themes, and movement often reveal stress, fear, withdrawal, or aggression.
Behavioural patterns: Changes in participation, attention, repetition, or withdrawal during creative activities can signal distress.
Self-awareness and resilience: Regular creative expression helps children process experiences and build coping skills.
Non-verbal communication: Art captures what surveys and questionnaires often miss.

Importantly, art-based observation does not label or diagnose children. It listens.

How can art-based monitoring work at scale?

Structured, regular art-based activities can be integrated into schools and community spaces throughout the year. This could include: weekly or monthly art sessions guided by trained facilitators, simple frameworks to observe themes, emotional tone, and engagement, digital archiving (with consent) to track patterns over time, and combining art insights with environmental and air-quality data.

Over large samples, patterns begin to emerge. For example, increased aggression, darker imagery, or withdrawal during high-pollution months may signal emotional strain. When combined with scientific pollution data, this creates a living, breathing mental health map.

A call to action

If air pollution is continuous, mental health monitoring must be too. We need to move beyond small studies and crisis-driven responses. Art offers a humane, scalable, and culturally rooted way to understand what children are experiencing, without waiting for harm to become illness.
Clean air policies protect lungs. But to protect minds, we must also learn to listen differently. Sometimes, the most important data is not spoken -- it is drawn, sung, danced, and imagined.
