A
neurotransmitter that is most known for regulating mood.
While the release of serotonin has been commonly
associated with producing feelings of happiness and content, it is a
misconception that this is its primary function (it's not). Serotonin's range of functions in the human body are very broad and complex. The chemical plays a crucial role in cognition, memory, reward, and learning as well as numerous physiological processes such as vomiting and the constriction of blood vessels. Without Serotonin, you probably would not even be alive.
Person 1: This video gives me so much serotonin.
Person 2: Same! I can feel the good vibes flow through me.
Me: I hate to be a
party pooper, but FYI Serotonin isn't entirely
responsible for giving you "the good vibes".
What you are describing is a complex rush of hormones and neurotransmitters made up of serotonin as well as dopamine, oxytocin, and other endorphins. These are commonly referred to as your "happy hormones".
