Which neurotransmitter is most closely associated with feelings of well-being, appetite, and mental alertness?

Serotonin is the neurotransmitter most closely associated with feelings of well-being, appetite, and mental alertness. It plays a critical role in regulating mood and has significant effects on emotional states. Elevated levels of serotonin are often linked to enhanced mood and feelings of happiness, while lower levels can contribute to conditions such as depression.

In addition to its influence on mood, serotonin is also involved in the regulation of various physiological processes, including appetite. It helps signal satiety, meaning it plays a key role in determining when we feel full after eating. Furthermore, serotonin impacts cognitive functions and mental alertness, contributing to optimal brain functioning.

Understanding serotonin's role aids in recognizing how it can influence behaviors and emotions in clients. This is particularly relevant in the field of addiction and counseling, where mood and appetite control can affect recovery journeys.
