What is the most important thing you can do to protect your respiratory system?

The most important thing you can do to protect your respiratory system is to avoid inhaling harmful substances.

You can reduce your risk of inhaling harmful substances and protect your respiratory system in the following ways:

* Avoid smoking. Smoking is the single most damaging thing you can do to your respiratory system. It can lead to lung cancer, COPD, and other respiratory problems.

* Stay away from secondhand smoke. Secondhand smoke contains the same harmful chemicals as firsthand smoke and can cause the same respiratory problems.

* Avoid inhaling dust and fumes. Dust and fumes from chemicals and other sources can irritate your respiratory system and cause inflammation, leading to respiratory problems such as asthma and allergies.

* Wear a mask when exposed to harmful substances. If you must work or otherwise come into contact with harmful substances, wear a NIOSH-approved respirator mask to protect your respiratory system from the risks of inhaling these substances.

* Maintain good indoor air quality. Ensure your indoor air is clean and free of harmful pollutants by:

- Increasing ventilation by opening windows and doors or using fans.

- Using an air purifier to remove dust, pollen, and other particles from the air.

- Avoiding the use of harmful chemicals, such as pesticides and cleaning products, indoors.

* Wash your hands regularly. Washing your hands with soap and water reduces exposure to germs, including those that can cause respiratory infections.

* Avoid contact with people who are sick. When possible, avoid contact with individuals showing signs of respiratory illness, such as coughing and sneezing, as they could transmit infectious diseases.

* Get vaccinated. Vaccines are available to protect against several respiratory illnesses, such as influenza, pneumonia, and COVID-19. Getting vaccinated can help reduce the risk of developing these infections and their associated respiratory complications.
