New Delhi:
World Lung Day is observed every year on September 25 to raise awareness about lung health and address the growing burden of respiratory diseases across the globe. Initiated by the Forum of International Respiratory Societies (FIRS) and its partners, the day emphasizes the urgent need to protect lungs for a healthier future.

One of the most alarming concerns in recent years has been the growing number of lung disease cases among children. While there are multiple reasons behind lung ailments in young ones, passive smoking also known as secondhand smoke remains a major but preventable cause.

Passive smoking damages children’s lungs in multiple ways. From limiting their natural growth to triggering chronic conditions, the harmful chemicals in tobacco smoke pose lifelong threats. Let’s understand how passive smoking affects the lungs of children.

Impact of Passive Smoking on the Lungs of Children

Reduced Lung Function

Children’s lungs and airways are still developing, which makes them more sensitive to harmful chemicals in secondhand smoke. Exposure to these toxins weakens lung capacity and slows down healthy lung growth. Over time, this reduced function can affect breathing ability and overall stamina.

Increased Risk of Asthma

Passive smoking is a well-established trigger for childhood asthma. Even brief exposure can inflame airways, causing wheezing, coughing, and shortness of breath. For children already living with asthma, secondhand smoke can lead to more frequent and severe attacks.

Higher Risk of Infections

Toxic particles in secondhand smoke weaken the immune defenses of the respiratory system. This makes children more susceptible to illnesses like bronchitis, pneumonia, and even ear infections. Frequent infections not only harm immediate health but also put children at risk of long-term respiratory complications.

Risk of Allergies and Chronic Conditions

Exposure to passive smoke heightens sensitivity to allergens, paving the way for recurring respiratory issues. Long-term exposure has been linked to a greater likelihood of developing chronic obstructive pulmonary disease (COPD) in adulthood, proving that the effects of passive smoking extend far beyond childhood.

Slower Recovery and Complications

Children exposed to passive smoke take longer to heal from common illnesses such as colds and coughs. Chemicals in smoke irritate and inflame the lining of the lungs, delaying recovery and increasing the risk of complications.

Why Awareness Matters

On World Lung Day 2025, the message is clear: protecting children from passive smoking is crucial for safeguarding their future. By creating smoke-free homes and environments, we can prevent countless cases of childhood respiratory illness and reduce the burden of lung disease globally.

Healthy lungs mean healthier lives and every step towards eliminating passive smoking brings us closer to that goal.
