Answer this question to the best of your ability:
Is it possible to measure the effectiveness of meditation objectively?
Yes, there are several ways to measure the effectiveness of meditation objectively. Studies have used techniques like brain imaging (fMRI, EEG), heart rate variability (HRV) analysis, and salivary cortisol assessments to understand the physiological changes associated with meditation. These methods provide evidence that meditation can lead to reduced activity in the amygdala (associated with stress), increased activity in the prefrontal cortex (associated with attention and self-regulation), and decreased levels of the stress hormone cortisol.
