11 Respiratory Health Tips for Better Lung Function

6. Improve Indoor Air Quality

Indoor air isn’t always cleaner than outdoor air without attention. Small changes can make a measurable difference. Use a HEPA air purifier in bedrooms and living areas to lower allergens and tiny particles. Increase ventilation by opening windows when outdoor air quality is good, or use exhaust fans while cooking to remove smoke and fumes. Avoid indoor pollutants such as tobacco smoke, heavy incense, unvented gas stoves, and frequent use of strong cleaning chemicals without protection. If you use mosquito coils or biomass at home, try to reduce exposure and ventilate during use. While houseplants offer some benefits, they do not replace filtration for fine particles. For people with allergies, regular cleaning of bedding and using allergen-proof covers can reduce triggers. For those in shared or rented housing, discuss practical ventilation improvements with landlords and choose portable purifiers if building-level changes aren’t possible. Small, steady upgrades often translate into easier breathing and fewer symptoms over months.
