Transcendental Meditation is scientifically proven effective against stress, anxiety, PTSD, burnout and sleep problems. A meta-analysis of 146 studies found TM more than twice as effective as other relaxation techniques for chronic anxiety. TM lowers the stress hormone cortisol by 30% and reduces PTSD symptoms by 20.5%. The technique brings the body into a state of deep physiological rest, naturally releasing accumulated tension. TM is practised for 20 minutes twice daily and most people experience effects from the very first session.
