Is it true that when you breathe in air also dust pollen and microorganisms?

Yes, when you breathe in, you also take in dust, pollen, and microorganisms. The air we breathe is not pure oxygen. It contains many other particles. Some of these particles can be harmful to our health. Dust and pollen can cause allergies and asthma. Microorganisms, such as bacteria and viruses, can cause infections.

Most of the time, the amount of harmful particles in the air is not enough to cause any problems. But sometimes, the levels of these particles can increase. This can happen during a dust storm, wildfire, or when there is a lot of pollen in the air. When this happens, it's a good idea to stay indoors as much as possible.

If you suffer from allergies or asthma, you should talk to your doctor about ways to protect yourself from these particles. They may recommend that you wear a mask when you go outdoors or use an air purifier in your home.
