Air pollution is becoming an increasing concern, particularly for children. From traffic emissions and construction dust to smoke and fine particulate matter, children are exposed to several pollutants in their daily environment. At the same time, more children are experiencing symptoms such as frequent sneezing, a blocked or runny nose, itchy eyes, coughing and wheezing.
So, is there a connection between pollution and allergies in children? Yes. Research suggests that air pollution can contribute to the development and worsening of respiratory allergies, particularly allergic rhinitis and asthma. Children may be especially vulnerable because their lungs and airways are still developing.
How does air pollution affect allergies?
Air pollution comprises various gases and particulates. The fine particulate pollution can enter deep into the respiratory system. Various pollutants, including nitrogen dioxide (NO₂), sulphur dioxide (SO₂), and ozone and particulate matter, may irritate the airways and cause inflammation.
Pollution may affect allergies in several ways:
- Irritates the airways: Pollutants can irritate the sensitive lining of the nose and respiratory tract.
- Triggers inflammation: Fine particles can promote inflammatory responses in the airways.
- Worsens allergic symptoms: Children who already have allergies may experience more frequent or severe symptoms when exposed to polluted air.
- May increase allergic sensitisation: Air pollutants can potentially make the respiratory system more reactive to allergens such as pollen, dust mites and other environmental triggers.
What allergy symptoms should parents watch for?
Pollution-related irritation and allergies can sometimes produce similar symptoms. Parents should watch for:
- Frequent sneezing
- Persistent or recurrent runny nose
- Blocked or stuffy nose
- Itchy nose or throat
- Watery or itchy eyes
- Recurrent coughing
- Wheezing or breathing difficulty
- Symptoms that worsen after outdoor exposure
- Repeated episodes of nasal congestion or respiratory symptoms.
Can pollution make existing allergies worse?
Yes. Children suffering from rhinitis and asthma can be affected more by poor air quality because the pollutants can irritate their air passages and worsen their condition.
As mentioned by the Indian Academy of Pediatrics, children are especially susceptible to pollution both outdoor and indoor. Air pollution is one of the emerging causes of respiratory allergy in children.
How can parents reduce a child's exposure to pollution?
Completely avoiding air pollution may not always be possible, but parents can take practical steps to reduce exposure:
- Avoid outdoor exercise when air quality is poor.
- Keep children away from areas with heavy traffic, construction dust or smoke whenever possible.
- Avoid smoking inside or near the home.
- Keep indoor spaces well- ventilated when outdoor air quality permits.
- Reduce indoor sources of smoke and strong fumes.
- Follow the treatment plan prescribed by the child's doctor if the child has an existing allergy or asthma.
- Seek medical advice if symptoms are frequent, persistent or affecting sleep, school or daily activities.
When should a child visit the doctor?
In case the symptoms appear similar to allergies and continue on for some time, the best thing would be to get them checked out by a doctor. If there is any kind of recurring wheezing, trouble breathing, persistent cough, or a worsening of the symptoms due to environmental factors, then a visit to a pediatric allergy specialist will become necessary. This is because the pediatric allergy specialist can examine the symptoms of the child and the medical history.
Conclusion
The link between air pollution and allergies is gradually being understood, especially among children. Exposure to these pollutants irritates the air passages, triggers inflammation, and increases the severity of symptoms for kids suffering from respiratory allergies.
Although parents cannot change the air quality outside by themselves, measures like avoiding needless exposure to such air will go a long way towards safeguarding the respiratory system of your child. In case your child frequently suffers from symptoms like sneezing, runny nose, coughing, wheezing or itchy eyes, then it would be better to consult a pediatric allergy specialist about this problem.
