What effect does serotonin have on a person's mental state?

Serotonin is a neurotransmitter that plays a significant role in regulating mood, emotion, and overall mental state. Its presence is strongly linked to feelings of well-being and happiness. An adequate level of serotonin in the brain is associated with improved mood and a reduction in anxiety, making individuals feel more stable and less prone to depressive symptoms.

Research indicates that when serotonin levels are balanced, individuals often experience enhanced emotional resilience, leading to a generally positive mental outlook. This effect is particularly important in the context of mental health treatment, as many antidepressants aim to increase serotonin levels to alleviate symptoms of depression and anxiety disorders.

While serotonin influences various physiological processes, including appetite and cognition, its most prominent and well-researched role relates to mood regulation. Thus, its impact on improving mood and reducing anxiety is widely acknowledged in both clinical practice and psychological theory.
