From the Abstract. The majority of cancer patients use some complementary medicine modality. Mind-body practices, and especially meditation, are amongst the most utilized. Research shows that they help cancer patients manage psychological distress and control symptoms such as pain, nausea, and sleep disturbances. However, the effects of a single meditation session on self-reported symptoms, including physical, psychological and symptom distress in an outpatient setting, are largely unknown.
All patients [received] an individual meditation consultation (60 minute initial visits, and 30 minute follow-up visits). Our analysis included 81 meditation visits for 121 participants over 32 months. The [results] revealed a significant reduction from pre- to post-meditation session in physical, psychological, and symptom distress component scores. The greatest mean reductions for individual symptoms were for: Anxiety, Fatigue, Distress, Well Being, Sleep, and Pain; all changes reaching statistically and clinically significant thresholds.
Further research with a larger sample size is needed to better understand the symptoms that meditation can help control and the frequency of self-practice outside of the clinic to help maintain the long-term benefits.

Four themes were identified: the impact of mindfulness on sleep and motivation to adopt a healthy sleep lifestyle; benefits of mindfulness on aspects of life beyond sleep; challenges and successes in adopting mindfulness-based practices; and the importance of group sharing and support. Participants said they were not sleeping more, but sleeping better, waking more refreshed, feeling less distressed about insomnia, and better able to cope when it occurred.
Some participants experienced the course as a call to action, and for them, practicing meditation and following sleep hygiene guidelines became priorities. Motivation to sustain behavioral changes was reinforced by feeling physically better and more emotionally stable, and seeing others in the MBSR class improve. The body scan was identified as an effective tool to enable falling asleep faster. Participants described needing to continue practicing mindfulness to maintain benefits.

Conclusions (from the Abstract): Findings of this exploratory trial suggest that an 8-week meditation program* may offer an acceptable and effective intervention for reducing perceived stress and improving certain domains of sleep, mood, and memory in adults with cognitive impairment and their caregivers.

There is growing scientific interest in assessing the biological correlates of non-pharmacological interventions such as mindfulness. Examinations of the beneficial effects of mindfulness on hypothalamus-pituitary-adrenocortical system activity (HPA SA) and sleep are sparse.
The aim of the present study was to explore the impact of long- and short-term meditation experience on HPA SA and sleep. There were 20 participants, 9 of whom had long-term experience in meditation (mean = 264 months) and 11 novices. Novices underwent an 8-week course in Mindfulness-Based Stress Reduction (MBSR), and cortisol samples were taken in the lab at the beginning and end of the course. To assess the cortisol awakening response, 4 morning cortisol samples were collected. Sleep and mindfulness were assessed by self-rating questionnaires.
Among participants with long-term meditation experience, morning cortisol decreased with length of experience. For novices, after an 8-week introductory MBSR course, morning cortisol levels had decreased, while both sleep and self-attribution of mindfulness significantly improved. Cortisol levels did not, however, change between the beginning and end of individual MBSR sessions. The pattern of results lends support to the view that MBSR/meditation has a favorable influence both on biomarkers of stress regulation, such as cortisol secretion, and on sleep.
