How can I protect my child from air pollution?

No parent should have to worry that the simple act of breathing could harm their child. But in East Asia and the Pacific, where children in every country are exposed to unhealthy levels of air pollution, it’s a daily reality for millions of families.

As a parent it’s easy to feel powerless. But there are simple, effective steps you can take to reduce your children’s exposure and protect them from the worst effects. 

To help, UNICEF experts from East Asia and the Pacific have answered parents’ most urgent questions about protecting children from air pollution. 

“What is causing air pollution?”

Air pollution comes from many places. UNICEF and partners have identified 7 deadly sources of air pollution. These 7 sources are:

• Household air pollution
• Traffic-related air pollution
• Waste-related air pollution
• Industrial air pollution
• Wildfire and landscape fire smoke
• Sand and dust storms
• Second-hand smoke

All these sources of air pollution release high levels of PM2.5 — a type of tiny pollution particle that harms health the most.  

In East Asia and the Pacific, the most harmful air pollution comes from the burning of fossil fuels and biomass fuels in vehicles, power plants, factories, and industrial facilities along with coal, wood, and charcoal-burning stoves in homes and the burning of farming waste.

These activities release toxic particles that build up in the air, especially in cities. Dust swept up by the wind, sandstorms and wildfires worsen the situation, spreading pollutants over vast distances.

Even behind closed doors, children aren’t fully protected. Indoor air pollution can be an even greater, often overlooked threat. It’s one of the leading ways children in the region are exposed to harmful pollutants. 

Nearly 36 million children in East Asia and the Pacific live in countries that mostly use coal, charcoal and wood-burning stoves that give off dangerous toxic smoke.

While these solid fuels are affordable and widely available, they produce smoke and toxic pollutants that are often trapped inside homes and build up continuously. 

In some homes, second-hand smoke from cigarettes adds more pollution to the air.

Indoor air pollution isn’t just a problem in homes, it’s in schools, health facilities and other spaces where children spend time too.  

“Why is air pollution so dangerous for children?”

Air pollution is dangerous for children for many reasons:

• Children are smaller and breathe faster than adults. They inhale more air per kilogram of their body weight than adults — and more pollutants.
• Children’s nasal passages are less effective at filtering pollutants, so they absorb more from the air.
• Children breathe air that is closer to the ground, including dust and vehicle exhaust fumes.
• Children are still growing. Air pollution can damage their growing lungs, bodies and brains — leading to lifelong health issues.
• Children’s immune systems are weaker than adults, so they’re more vulnerable to viruses, bacteria and other infections.

“How does air pollution harm children?”

Immediate and long-term health problems

The tiny toxic particles in polluted air, including PM2.5, can enter children's growing lungs and damage them. This can cause breathing issues, illnesses and long-term health problems, including: 

• Pneumonia,
• Bronchitis,
• Chronic coughs,
• Ear infections,
• Asthma,
• Allergies,
• Eczema,
• Heart disease,
• Cancer.

Air pollution can also weaken children’s immune systems and make existing health conditions worse.

Unlike a scraped knee or a fever, the damage air pollution causes isn’t always immediately visible. It builds up over time. Adults who were exposed to air pollution in the womb and as babies and toddlers are sadly likelier to develop respiratory problems later in life.

Death

It’s scary, but also important to know that in some cases, the health problems caused by air pollution can lead to children dying.

Developmental delays

Air pollution can affect children’s learning, thinking and brain development. 

A future with fewer opportunities

Breathing polluted air saps children’s energy, making them tired with less energy to learn and play. When they get sick, they often miss school, further limiting their learning and development and leading to lower academic performance. 

“Which children are most at risk from air pollution?”

It's important to know that your child may be at higher risk if they are young, live near factories, busy roads, or industrial zones, or have pre-existing health conditions, like asthma and heart disease. 

Children exposed to air pollution over a long time are also more at risk than children exposed occasionally. This includes children who live in homes that use coal, charcoal or wood-burning stoves, especially indoors.

“How dangerous is air pollution for pregnant women and their babies?”

If you’re pregnant it’s important to know that air pollution is harmful for you and your unborn baby and can make pregnancy more dangerous.

Breathing polluted air during pregnancy has been linked to high blood sugar, high blood pressure, pre-eclampsia, respiratory illnesses, depression after childbirth and increased rates of miscarriage and stillbirth. Tiny pollution particles (like PM2.5) can also reach your growing baby, putting them at more risk of respiratory illness, developmental difficulties and a weakened immune system. 

It’s scary. But the good news is that by taking a few precautions, you can greatly reduce your exposure to air pollution and support a healthy pregnancy. Stay inside when air pollution levels are high, wear a well-fitting mask, and stay away from smoke (including from coal, charcoal and wood-burning stoves and cigarettes).

Remember your body is doing an incredible job of growing and protecting your baby. These precautions can help it keep doing just that.

“How can I protect my children from outdoor air pollution?”

You can take these steps to better protect you and your children from breathing polluted air outdoors:

• Check the air quality in the area where you live every day. This information can often be found in the local news, on government websites or on apps like Plume or IQAir — that you can download onto your phone for free. 
   
• Use air quality information to help you make wise decisions for your family. When outdoor air pollution levels, especially PM2.5, are high:
  • Try to stay indoors.
  • If you need to go outside, try to go at times of the day when air pollution levels are lower (this can be different times in different places, so always check).
  • Help children avoid strenuous activity, including play and exercise. This is especially important if children have medical conditions like asthma or other respiratory infections.
• Close windows and doors during high pollution, to help keep pollutants out.
   
• Avoid roads with lots of traffic. If you have to walk down a busy road, carry your child if you can, so they’re higher above vehicle exhaust fumes. 
   
• Avoid industrial areas, including close to factories and power plants, and areas where waste is being burned. 
   
• Help your child wear a well-fitting mask:
  • Masks should cover the nose, mouth and chin, with no gaps.
  • KF94, KN95, or FFP2 masks are a good choice because they’re comfortable and block out harmful pollutants like PM2.5.
  • You should get a mask size that is a suitable for your child’s age.
  • In some circumstances masks may not be appropriate for your child. During the COVID-19 pandemic, the World Health Organization (WHO) recommended that children under the age of 5 years old should generally not wear a mask, because they may have difficulty wearing one.
  • WHO don’t have specific recommendations on mask use for children in polluted environments, so It’s best to check with your health provider to see what they recommend based on your child’s age, health and the local air quality. 

• Healthy children are less likely to face problems from breathing polluted air. Look after your child’s overall health by:
  • Keeping up with their vaccinations.
  • Feeding them a healthy diet with enough essential micronutrients. These foods, high in vitamin C, E, and omega-3 fatty acids, can be especially beneficial:
    • Vitamin C: Guava, papaya, pineapple, citrus fruits (e.g. oranges, limes), bell peppers.
    • Vitamin E: Nuts and seeds, green leafy vegetables (e.g. spinach, broccoli).
    • Omega 3 antioxidants: Seafood and fish (e.g. tuna, mackerel), seaweed, walnuts, flaxseeds.
  • Keeping them active.
  • Breastfeeding babies for at least six months.
• Stand with parents across the region to call for change. Join a local or national movement to call for policies that reduce air pollution and protect children. 

How can I protect my children from indoor air pollution?

You can take these steps to better protect your children from breathing polluted air indoors:

• Cook in well-ventilated spaces: Open windows when cooking and use an exhaust fan to allow heat and fumes to escape.
• Use cleaner fuels and technologies to cook, heat and light your home: If possible, choose electricity, natural gas, liquefied petroleum gas, biogas or solar stoves or ovens.
• Maintain stoves, chimneys and other appliances so that they burn fuel efficiently.
• If ventilation is challenging, or you can’t use clean fuel, cook outdoors.
• Keep pregnant women and children away from smoke.
• Make sure everyone in the household avoids smoking indoors and near children and pregnant women, to protect them from second-hand smoke.
• Avoid burning candles and incense and using air fresheners, as they can add toxic chemicals to the air.
• Be aware of other common sources of indoor contaminants, including building and paint products, cleaning supplies and household chemicals — keep children away from them and use natural alternatives where possible.
• Use an air purifier with HEPA filters for your home, if your budget allows, which can greatly absorb indoor pollutants.
