Ditch these 8 habits for healthy lungs, lower risk of asthma, lung cancer, tuberculosis, and more

World Lung Day, observed annually on September 25th, is a global health awareness day dedicated to promoting lung health and advocating for the prevention and management of lung diseases. It is organised by the Forum of International Respiratory Societies (FIRS), it highlights the importance of healthy lungs and raises awareness about the impact of conditions like asthma, chronic obstructive pulmonary disease (COPD), lung cancer, and tuberculosis. Dr Arjun Khanna, a leading pulmonologist at BreatheWell Institute of Pulmonary Care, talks about 8 daily habits or practices that are secretly destroying our lung health.

Smoking or vaping

Even infrequent smoking or vaping introduces harmful chemicals like nicotine, tar, and formaldehyde into your lungs, damaging lung tissues and narrowing airways. This leads to chronic respiratory diseases like COPD and increases the risk of lung cancer. The toxic particles cause inflammation and scarring in the lungs, which progressively worsens over time, even with low levels of use.

Exposure to indoor pollutants

Daily exposure to cleaning agents, air fresheners, and synthetic fragrances releases volatile organic compounds (VOCs) into the air, which irritate lung tissues and contribute to respiratory issues. These chemicals can cause lung inflammation, worsen asthma, and trigger allergic reactions. Long-term exposure may increase the risk of developing chronic lung conditions due to the constant irritation from airborne pollutants.

Lack of physical activity

A sedentary lifestyle limits the lungs' capacity to efficiently process oxygen, weakening respiratory muscles over time. Without regular exercise, lung function diminishes, leading to breathlessness, reduced stamina, and poor circulation. Over time, this can contribute to respiratory problems like shallow breathing and decreased lung elasticity, affecting overall respiratory health and endurance.

Not maintaining proper ventilation

Inadequate ventilation in enclosed spaces causes pollutants, mould spores, and allergens to accumulate, reducing air quality. Prolonged exposure can lead to lung irritation, asthma, and other respiratory conditions. Stagnant air filled with dust and toxins harms the lungs by introducing irritants that the respiratory system struggles to expel, increasing the likelihood of infections and allergies.

Breathing in workplace toxics

Constant exposure to industrial chemicals, dust, or fumes in work environments poses a serious threat to lung health. Inhaling toxic particles leads to occupational lung diseases like asbestosis, silicosis, or even lung cancer. Without protective gear or proper ventilation, daily exposure can cause irreversible damage to lung tissues, leading to chronic respiratory issues over time.

Ignoring hydration

Lack of sufficient water intake can cause the mucus in your lungs to thicken, making it difficult for your body to expel it. This leads to blocked airways, a higher risk of respiratory infections, and increased difficulty in breathing. Proper hydration keeps the lungs moisturised, helping them function optimally by clearing mucus and toxins efficiently.

Neglecting to clean air filters

Dust, pet dander, pollen, and other allergens accumulate in air filters over time. When these filters are not cleaned regularly, they recirculate polluted air throughout your living spaces. Breathing in these pollutants irritates the respiratory system, causing lung inflammation and worsening conditions like asthma, bronchitis, or other respiratory diseases.

Overeating processed foods

Processed foods high in unhealthy fats, sugars, and preservatives can trigger lung inflammation, similar to how they affect other organs. These foods lack essential nutrients that support lung health and increase the risk of respiratory conditions. Poor diet weakens the immune system, leaving the body more vulnerable to respiratory infections and chronic lung diseases.
