"In a study published in the International Journal of Neuroscience, researchers discovered that massage therapy can increase serotonin levels by 28% and dopamine by 31%. It also decreases cortisol levels by 31%.
Serotonin is a hormone that helps to stabilize mood and promote good sleep patterns. Similarly, dopamine is often referred to as the “happy chemical” as it’s the one responsible for feelings of happiness. On the other hand, cortisol is regarded as the main stress hormone. It’s responsible for the spike in your blood pressure and heart rate when you’re experiencing stress."
