The human microbiome is the totality of all the bacteria, viruses, and other microorganisms that live on or in the human body. It's estimated that there are trillions of them, and they play a vital role in human health. The nasal microbiome is one part of the human microbiome, and it's specifically concerned with the bacteria that live in your nose.
A healthy nasal microbiome is important for several reasons. First, it helps protect you from infection by keeping bad bacteria out of your nose. Second, it helps to regulate your immune system. And third, it can have a direct impact on your overall health by influencing everything from how well you sleep to how much weight you lose or gain.
Unfortunately, there's still a lot we don't know about the nasal microbiome. More research is needed to determine exactly what role it plays in human health and how we can best maintain a healthy one. In the meantime, though, there are some things you can do to keep your nasal microbiome healthy and functioning at its best.
