Meditation: A Strategy With Promise in Chronic Disease
Regardless of successful biomedical intervention and relative control of a disease process, individuals may still experience chronic stress, depression, anxiety, and diminished social capital for weeks, months, or even years after diagnosis.1,2 These experiences not only lead to lower quality of life but can contribute to relapse and even increased mortality in some cases.1 For this reason, scientists and clinicians have recognized the need for holistic treatment of chronic disease, addressing the physical, psychological, and social needs of patients to achieve optimal outcomes.
In this issue, Heo et al3 present work in which they examined the feasibility, acceptability, and initial efficacy of a holistic meditation intervention in patients with heart failure. Meditation is (generally) defined as the action of deeply focusing attention and awareness, with an attempt to let go of stressors and promote feelings of physical and mental well-being.4 Meditation can be performed in silence, guided by voice (eg, another person, an audio-recording) or by music, performed in seated or lying position, or even performed while walking or working.4–7 It can be used for relaxation or can be deeply purposeful (eg, focused thoughts of self-compassion and affirmation).5 With its promise as a stress reduction technique, it is not surprising that some studies have indicated that meditation may improve quality of life by helping people achieve a relaxed physical state, improve sleep, improve blood pressure, combat negative emotions, and even relieve unpleasant symptoms (eg, pain, anxiety, depression).4,6,8,9
Despite their potential, meditation interventions are in relative infancy stage in the literature. To date, many meditation intervention studies have been conducted with small samples and have methodological limitations such as lack of control, high variability of intervention delivery and evaluation, and lack of information on intervention follow-up and dosing.4–6,8–11 This has led to modest (although typically positive) results and many recommendations for more rigorous research in this area. This is quite understandable considering the rather nebulous nature of meditation as a practice. There is no specific method and very little information suggesting that 1 form of meditation is better or more effective than another. However, the results of both quantitative and qualitative inquiry on this topic suggest that meditation may be a promising self-management strategy.5,6,8,11
Taking a closer look at the potential of meditation as a health intervention reveals that it is a strategy with a great deal of potential to help people but is also quite ambiguous and difficult to comprehend. Apart from formal courses and materials, it is free of cost and can be performed almost anywhere. Although not a recommended solution for acute health crises or a replacement of biomedical treatments, the reported benefits of meditation correspond to traditional clinical wisdom such as encouraging a positive outlook, suggestions to eliminate unnecessary stressors, and getting sufficient rest.
