Meditation enhances brain functioning: 2
Greater activity in left pre-frontal cortex (seat of positive emotions, happiness), reduced activity in right pre-frontal cortex (seat of negative emotions, anxiety).
Produces high amplitude gamma wave synchrony (= expanded awareness, alertness, insight)
Improves learning and intellectual capacities Meditation enhances psychological functioning:3
Increases production of endorphins, decreases stress hormones (cortisol, adrenalin)
Helpful in easing trauma (military vets)
Decreases aggression, hostility, and recidivism in prisoners
Helpful in alleviating depression
Helpful in treatment of eating disorders
Helpful in obsessive-compulsive disorders
Gratitude meditations and journaling contribute to overall sense of happiness
Meditation enhances bodily health:4
Helpful in recovery from cancer
Helpful in dealing with chronic pain
Helpful in recovery from psoriasis
Helpful in weight loss and fitness
