What are the Mechanisms Behind Meditation's Health Effects?

The exact mechanisms through which meditation exerts its health benefits are not fully understood, but several hypotheses have been proposed. One theory suggests that meditation reduces the activity of the sympathetic nervous system, leading to decreased stress hormone levels. Another hypothesis is that meditation enhances the parasympathetic nervous system, promoting relaxation and recovery. Additionally, meditation may influence brain function and structure, leading to improved emotional regulation and cognitive processing.
