serotonin system
The serotonin system refers to how serotonin, a key neurotransmitter, functions in the brain and body. Serotonin helps regulate mood, emotions, sleep, appetite, and digestion. It's often called the "feel-good" chemical because higher levels are linked to feelings of happiness and well-being. Imbalances in this system can contribute to mental health issues like depression and anxiety. Serotonin is produced in the brain and intestines, and its effects are influenced by various factors, including genetics, diet, and lifestyle. Medications that target the serotonin system are often used to treat mood disorders.
