Gut microbes may influence sleep quality

Scientists have found that tiny pieces from bacteria in our gut, called peptidoglycan, might affect how well we sleep.

They saw more of this stuff in the brains of mice when they were sleep-deprived.

This suggests that the bacteria in our gut could be talking to our brains, even though our brains are usually protected.

However, this study was only done on male mice, so we don't know if the same thing happens in humans or in females.

There's still a lot we don't understand about how our gut and brain work together, but this research shows that they might be more connected than we thought.
