Why it matters
Meet the ecosystem that helps you breathe.
It turns out that respiratory health is closely connected to a microbiome (opens in a new tab): not the one in your gut (opens in a new tab) that's been in the news, but the one in your nose and mouth.
Like the microbiomes in your gut, in your lungs, on your skin, and around your genitals, it is an ecosystem of billions (yes, billions) of bacteria, fungi, viruses, and other microorganisms. Usually they conspire to help keep you healthy.
But sometimes they get disrupted. The disruption is called dysbiosis, and it can make you sick. Good respiratory hygiene can help prevent it.
