11 Respiratory Health Tips for Better Lung Function

10. Prevent Infections: Vaccines and Basic Hygiene

Protecting the lungs from infection reduces the risk of serious illness and long-term loss of function. Vaccines for influenza, pneumonia where appropriate, and up-to-date COVID-19 shots lower the chance of severe respiratory infections. Regular handwashing and staying home when sick help limit spread to family members, especially infants, older adults and people with chronic lung disease. If someone in the household is at higher risk, consider extra precautions during seasonal surges. For crowds or healthcare settings, mask use remains a reasonable option to reduce transmission. Simple home measures—cleaning high-touch surfaces, ensuring good ventilation when someone is ill, and asking visitors to postpone visits if unwell—reduce exposure. Talk to your clinician about which vaccines match your age and health status, and follow local guidance for boosters or seasonal shots. Prevention is a straightforward way to avoid setbacks to lung health.
