Why is Dust Dangerous For Your Health?

When you think about dust, you could say that these tiny particles are not dangerous. But science says different things. Airborne particles have a significant impact on our respiratory system, especially the lungs. If you are repeatedly exposed to dust over a longer period, you will, for sure, have more or fewer problems with your respiratory system. Some scientists have even linked dust to lung cancer.

But What is Dust?

Outside home dust is usually laid on the ground. You can see dust on the ground with a naked eye; mostly, it is made from sand or dirt. While being on the ground, dust is not that dangerous because when it is not airborne, it represents no danger to the human body.

Inside house dust is a bit scarier than outside because it is mostly made from dead skin and other in house debris. If you own pets, then pets dead skin contribute to the levels of dust in the home. However, people who are not suffering from allergic reactions are totally immune to this kind of dust. On the other hand, people who do suffer from allergic reactions to dust, pet dander, or dust mites may have severe reactions.

Dust Size

Like already mentioned, when dust accumulates on the ground, it is perfectly visible. You can blow at the dust on the ground, and then half of the dust is no longer visible to naked eye. This invisible dust is microscopic, and it is the most dangerous type of dust. Such a small particle can easily penetrate our immune system and get into the lungs. With constant inhaling of microscopic dust, you may get a lung infection.

In other words, even if you do see the dust in your home, it is a high chance that your home is invaded with microscopic dust. There is hardly any place in our home that is entirely free from dust.

People at Biggest Risk

Everyone is at some point, taking some kind of risk of inhaling the dust. Humans were inhaling dust for centuries, and we have found a way to live with that. Because of that, not many people have dust problems.

But some people, especially old people, people prone to allergic reactions and little babies, are at the biggest risk. Old people have weak lungs and a weak immune system, and any other component that triggers the immune system is just overload. 

Babies are also in a group of people that have a dust problem. Babies have a new immune system that still learns how to fight viruses, bacteria, and other infections. When babies are exposed to dust, then their immune system is not working properly, and it also gets overloaded, or it reacts drastically. 

Allergic Reactions

It is not a secret that dust, dust mites, and other things found inside the dust are triggering allergic reactions. Thankfully, these reactions are not severe and risk of getting anaphylactic shock is really a minimum. But itchy eyes, runny nose, and even rash is a possible reaction to dust.

Can You Do Something About Dust?

You should regularly clean the house. Use a damp cloth and wipe all the furniture and floor. In that way, you can without a problem remove most of the ground dust which can become easily airborne. Wiping the dust from the house is the first level of defense.

The vacuum cleaner is also a good option to remove dust. But be extremely careful if you are in the group of people who have problems with dust because vacuum cleaner will lift ground dust into the air. The best thing you can do is let someone else use the vacuum cleaner; someone you know will not get any reactions from inhaling the dust.

An air purifier is probably the number one device you can use to remove dust from your home. An air purifier with HEPA filter can remove 99.97% of airborne particles, including microscopic dust which is the most dangerous type of dust. Usage of an air purifier is extremely simple; you just plug it in and turn it on. If the air purifier has sensors for detecting air quality, it will work in automatic mode. An air purifier is extremely useful when used in combination with a vacuum cleaner. The vacuum cleaner will remove ground dust, and if some ground dust becomes airborne, the air purifier will suck it and remove it.


Dust is not some new monster at our door. It is a component with which we are living for centuries. The only thing different in the modern world is that now we understand that some diseases can be linked to inhaling the dust. By having that knowledge now, we can act and remove that part from the equation and live a healthier life than we were ever capable of living before.
