What is the primary role of serotonin in the body?

The primary role of serotonin in the body is to regulate mood. This neurotransmitter is crucial in the brain and plays a significant role in mood stabilization and emotional well-being. It helps to manage feelings of happiness and anxiety, influencing overall mood and emotional states. When serotonin levels are balanced, individuals typically experience improved mood and a sense of well-being, whereas imbalances can contribute to mood disorders such as depression.

While serotonin does play a part in other bodily functions, such as digestion and appetite regulation, its most recognized and impactful role is in mood regulation. This is why it is often referred to as the "feel-good" neurotransmitter, as it helps to promote a positive mood and emotional balance.
