Elderly tired of spending restless nights should learn Ancient Chinese martial arts tai chi chih for a good night's sleep, suggests a new study.
More than half of all older adults complain about having difficulties sleeping, however, researchers from University of California, Los Angeles have found that practicing tai chi chih, the Westernized version of a 2,000-year-old Chinese martial art can promotes sleep quality in older adults with moderate sleep complaints.
During the study, the team looked at 112 healthy adults between 59-86 years and randomly assigned to one of two groups for a 25-week period.
The first group practiced 20 simple tai chi chih moves; the other participated in health education classes that included advice on stress management diet and sleep habits.
At the beginning of the study, participants were asked to rate their sleep based on the Pittsburgh Sleep Quality Index, a self-rated questionnaire that assesses sleep quality, duration and disturbances over a one-month time interval.
They found that the tai chi chih group showed improved sleep quality and a remission of clinical impairments, such as drowsiness during the day and inability to concentrate, compared with those receiving health education.
The tai chi chih participants showed improvements in their own self-rating of sleep quality, sleep duration and sleep disturbance.
"Poor sleeping constitutes one of the most common difficulties facing older adults," said lead study author Dr. Michael Irwin, the Norman Cousins Professor of Psychiatry and Biobehavioral Sciences at the David Geffen School of Medicine at UCLA and director of the UCLA Cousins Centre for Psychoneuroimmunology.
