Serotonin is a molecule commonly found in your body, and is composed of Oxygen, Carbon, Nitrogen, and hydrogen. It is made up of 25 atoms total, and its chemical formula is C10H12N2O. When you normally think of serotonin, the word sleep immediately pops into your mind, and though serotonin does control your sleep cycle, its uses and properties don’t end there! Serotonin also controls mood, cognition, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction(the constriction of blood vessels). They also play a big part in controlling your emotions, particularly in making you feel happy, and for that reason are the most commonly prescribed type of antidepressant. Serotonin isn’t a molecule we encounter once a day and forget about, but rather a constant guest in our minds and bodies, helping us go to sleep, wake up, stay on time, and even stay happy!
