serotonin deficiency
Low happiness chemical
Serotonin deficiency is a shortage of serotonin, a neurotransmitter that regulates mood, sleep, and appetite.
The concept is often invoked to explain depression, though the relationship between serotonin levels and mental health is more complex than popular accounts suggest: My doctor thinks my anxiety might be related to serotonin deficiency.
