Serotonin
A neurotransmitter that regulates mood, increased by massage.
Serotonin is a neurotransmitter that contributes to feelings of well-being and happiness. It also plays roles in sleep regulation (as a melatonin precursor), appetite, and pain perception. Massage therapy has been shown to increase serotonin levels by approximately 28% per session, contributing to improved mood, better sleep quality, and enhanced emotional regulation.
