Recent surveys by the Wounded Warrior Project have found sleep disturbance to be the single biggest problem cited by veterans. The hyper-vigilance associated with posttraumatic stress (PTS) undermines the ability to sleep deeply and for extended periods of time. More generally, stress undermines sleep. The growing prevalence of stress in our society today accounts for the fact that nearly half the adult U.S. population reports occasional insomnia and 10% has chronic insomnia.
Scientific research indicates that the Transcendental Meditation® (TM) technique reduces insomnia by approximately 30% to 65% as measured by a standard scale. Veterans with PTS report that improvement in sleep is one of the first benefits of TM® practice, with improvement often coming within the first several days of learning the technique. New findings from a cohort of 143 veterans funded by the Wounded Warrior Project to learn TM found a 26% improvement in sleep on the MOS Sleep Scale in the first month of TM practice.
