Here’s abstract on a study I found last week. This is a great example of mind-body integration. Perhaps most of us know that constant worrying , suppressing negative emotions , being in toxic relationships and stressful work situations keep us a wake at night. But how many of us accept that thoughts and feelings affect the body at a cellular level? It is more widely accepted now that inflammation is associated with depression. Research has found a correlation between elevated inflammatory markers and patients with depression. We don’t know whether inflammation can cause depression and it is unlikely it would in all cases because depression is a difficult concept to pin down and some argue against the validity of mental illness because it ignores the body.
In this study on treatments for insomnia the adults were divided into 3 groups. One group undertook cognitive-behavioural therapy (CBT) for insomnia. Another group were taught tai chi chih (TCC) and the third group attended a regular sleep seminar education. Inflammation markers were measured before commencement of interventions and then at follow-up periods.
What is interesting is CBT and TCC are completely different in almost every way. CBT is a mind based therapy. TCC is a form of exercise which consists of series of movements completed in a sequence. People often see TCC as a form of mediation. CBT is self-reflective and self-analytical. TCC shifts our focus out of ourselves and into our body in which we feel each movement. Two very different methods and both seemed to reduce inflammatory levels.
Firstly this is good news because it shows there is more than one way to help with your sleep problem, well in this case insomnia associated inflammation. Secondly it shows that the body and mind are one. It would have been useful if this study had measure the sleep improvements instead of just inflammatory markers.
Sleep disturbance is associated with activation of systemic and cellular inflammation, as well as proinflammatory transcriptional profiles in circulating leukocytes. Whether treatments that target insomnia-related complaints might reverse these markers of inflammation in older adults with insomnia is not known.
MethodsIn this randomized trial, 123 older adults with insomnia were randomly assigned to cognitive-behavioral therapy for insomnia (CBT-I), tai chi chih (TCC), or sleep seminar education active control condition for 2-hour sessions weekly over 4 months with follow-up at 7 and 16 months. We measured C-reactive protein (CRP) at baseline and months 4 and 16; toll-like receptor-4 activated monocyte production of proinflammatory cytokines at baseline and months 2, 4, 7, and 16; and genome-wide transcriptional profiling at baseline and month 4.
As compared with sleep seminar education active control condition, CBT-I reduced levels of CRP (months 4 and 16, ps < .05), monocyte production of proinflammatory cytokines (month 2 only, p < .05), and proinflammatory gene expression (month 4, p < .01). TCC marginally reduced CRP (month 4, p = .06) and significantly reduced monocyte production of proinflammatory cytokines (months 2, 4, 7, and 16; all ps < .05) and proinflammatory gene expression (month 4, p < .001). In CBT-I and TCC, TELiS promoter-based bioinformatics analyses indicated reduced activity of nuclear factor-κB and AP-1.
Among older adults with insomnia, CBT-I reduced systemic inflammation, TCC reduced cellular inflammatory responses, and both treatments reduced expression of genes encoding proinflammatory mediators. The findings provide an evidence-based molecular framework to understand the potential salutary effects of insomnia treatment on inflammation, with implications for inflammatory disease risk.
