Serotonin, on the other hand, functions as a multifaceted neurotransmitter, contributing not only to mood regulation, but also playing a central role in appetite control, sleep modulation, and pain perception. . This symphony of molecules works together to induce a feeling of tranquility, gently guiding you toward a peaceful night’s sleep, explains Sharma.
