A 2007 study looked at using a combination of meditative practices and insomnia-specific cognitive behavioral therapy to treat insomnia. 30 adults with insomnia participated in a six-week trial that included a variety of non-pharmacological insomnia treatments, such as mindfulness meditation (which included body scans), sleep hygiene, sleep restriction, stimulus control, and sleep education. Thorough evaluations were conducted before and after the trial, and participants were also asked to keep sleep diaries which were assessed weekly. The researchers found significant improvements in insomnia symptoms and reductions in pre-sleep wakefulness and effort needed to fall asleep. These results were correlated with the number of meditation sessions performed. More information about cognitive behavioral therapy can be found in a later section.
The following year, a follow-up study was conducted to see how the treatments had fared in the long-term. Data was gathered at 6 and 12 months post-treatment from sleep diaries and questionnaires. The researchers found that many of the benefits from the treatment were still visible even a full year after the trial.
A 2014 study evaluated the effectiveness of mindfulness meditation (including body scans) as a treatment for insomnia. Those who meditated were found to have lower scores on scales of pre-sleep wakefulness, time spent awake, and general insomnia symptoms than those who did not, suggesting that body scans and other forms of mindfulness meditation could be an effective alternative treatment for adults with chronic insomnia.
