The Hidden Ecosystem of Sleep

Your mouth contains an entire ecosystem that changes while you sleep. Scientists found that

longer sleep creates more diverse bacterial communities in your mouth. During sleep,

saliva production drops, oxygen levels shift, and the pH balance changes. These shifting conditions

create unique microbial neighborhoods where different bacteria thrive or wait. The longer you

sleep, the more time these communities have to trade nutrients. Remarkably,

this oral diversity directly correlates with your better overall health. Your mouth acts

as a biological clock, transforming invisibly every single night.
