Description
Chris Masterjohn explains that everything the public has been taught about serotonin is wrong. Serotonin's primary role is not to boost mood. It is to help your mitochondria adapt to oxygen deficits across your entire body. It controls your breathing rate, moves food through your gut, and regulates blood flow inside your lungs. The idea that it is a happiness chemical is a marketing campaign that arose because of the SSRI industry in the 1980s. This one clip changes how you think about antidepressants entirely.
