Even voluntary laughter can influence mood because the body still changes breathing, facial muscles and social signals during the act of laughing.

Your gut and brain communicate through nerves, hormones, immune signals and microbes, which is why stress and digestion can affect each other.

The adult brain can still reshape connections through neuroplasticity, so practice and experience keep changing the organ you think with.

The brain has a waste-clearance system, especially active during sleep, that helps wash by-products out of brain tissue.

Placebos can trigger real brain and body changes, especially in pain, because expectation itself is part of how symptoms are processed.
