In a controlled trial¬†in the medical center at Rush University in Chicago the effect of Mindfulness meditation and insomnia involved 50 adults with chronic insomnia. Three groups were formed in the first standard protocol MBSR ( mindfulness -based stress reduction) was applied , a second group followed a MBTI¬†therapy ( mindfulness -based therapy for insomnia ) specific for insomnia and the third group had only monitoring. The study lasted about 6 months and several parameters related to insomnia like wake time ( TWT ), the pre -sleep arousal scale ( PSAS ) and the Insomnia Severity Index ( ISI ) were monitored.
During these 6 months the MBSR group met for 2,5 hours weekly for 8 weeks and participated in a 6 hours meditation retreat. They were asked to meditate 30-45 minutes a day at least 6 days a week. The MBTI group performed meditation for similar time.
The parameter measured showed that both approaches, MBSR and MBTI are¬†better than monitoring to improve these parameters. Significant improvement was obtained for TWT, PSAS and ISI during the sis months. No meaningful difference was found between MBSR and MBTI.
It concludes that mindfulness is an effective treatment for chronic insomnia in adults and subjects further studies with large sample size and comparing with other treatments.
