What is it?
The most researched form of meditation is mindfulness-based stress reduction (MBSR). It is typically offered as an 8-week program and uses sitting meditation, a sensing practice called body scan to reestablish the connection of mind to body and breath, and walking meditation to apply these practices in moving form.
MBSR can help reduce distress, fatigue, and pain. It improves mental functioning, mood, and well-being, including in cancer patients undergoing treatment.
Meditation may also help reduce blood pressure and heart disease risks, and can also benefit children, helping to improve self-confidence and coping skills.
Repeated practice and patience are important mechanisms to allow for optimal benefits.
What are the potential uses and benefits?
- Anxiety
Several studies show that meditation reduces anxiety associated with many diseases including cancer. - Cognitive impairment
MBSR practice resulted in improvements in cognitive impairment resulting from cancer and its treatments. - Depression
Many clinical trials indicate that MBSR can help reduce depression. - Fatigue
Studies in breast cancer survivors show that MBSR practice decreases fatigue severity. - Insomnia
MBSR may help relieve insomnia and improve sleep quality. - Lifestyle modification
Meditation practice may help support making lifestyle changes or modifying behaviors. - Mood disturbance
MBSR practice helps improve mood disturbance in patients including those with cancer. - Pain
A few studies indicate that MBSR is useful in relieving chronic pain. Larger trials are needed.

For Healthcare Professionals
Clinical Summary
Meditation has been practiced for millennia in many traditions around the world. It is defined as “a wakeful hypo-metabolic physiologic state” (1) in which the practitioner is relaxed but focused and alert.
In addition to developing attention, most formats include regulated breathing and developing nonjudgmental awareness. Common goals include inner calmness, physical relaxation, psychological balance, and improved vitality and coping. The most researched form of meditation is mindfulness-based stress reduction (MBSR), typically offered as an 8-week program.
Meditation can help reduce

It can also help improve
- Coping skills
- Well-being
- Awareness
- Cognition
Oncology guidelines recommend meditation
Both the American Society of Clinical Oncology (ASCO) (63) and Society of Integrative Oncology (SIO) (24) (50) recommend meditation for anxiety, stress reduction, depression, mood disturbance, and improved quality of life in cancer patients. In addition, the American Heart Association added meditation to intervention guidelines to possibly reduce risk of heart disease (51).
Improved psychological symptoms and functioning
Many studies (6) (10) (13) (15) (16) (17) (18) (20) (21) (22) (47) (48) (59) (65) (66) (70) (71) (72) (74) (76) (77) (83) show that mindfulness and other forms of meditation can boost positive emotions and significantly reduce stress, anxiety, depression, pain, and fatigue. Mindfulness-based interventions have also been found to be noninferior to escitalopram for anxiety (89) and superior to supportive expressive group therapy among distressed breast cancer survivors (46). There is also modest evidence for its use among people of color (84).
Meditation and mindfulness interventions may reduce blood pressure (85), optimize immune function, and reduce levels of various stress biomarkers including cortisol and IL6 (49) (67) (68). Other data suggest meditation can improve coping (23), cognition (18) (19) (78) (86), and psychological functioning (13) (14).
Virtual mindfulness-based interventions have also shown benefit (81) (82) (87). MSK offers free meditations online and with our Integrative Medicine at Home program. Both offer an opportunity to try guided meditations geared towards concerns relevant to cancer patients.
Mixed or lacking evidence for other conditions
Mindfulness-based interventions may help support behavior change (11) (45) (61) (62) and improve sleep quality (15) (54), but meta-analyses found inconclusive evidence for benefit in substance use disorders or for sleep parameters in cancer survivors (79) (80). Another study did not find benefit with MBSR for chronic neuropathic pain (88).
Purported Uses and Benefits
- Anxiety
- Cognitive impairment
- Depression
- Fatigue
- Insomnia
- Lifestyle changes
- Pain
Mechanism of Action
Meditation may affect changes in structural and functional aspects of the brain involved in regulating attention, emotion, and self-awareness (25) (28). MRI studies suggest various techniques correlate with behavioral improvements in attention, compassion, and cognitive perspective-taking: mindfulness or presence training increased cortical thickness in prefrontal regions; loving kindness or metta (affect) meditation induced plasticity in frontoinsular regions; and observing-thoughts or perspective meditation induced changes in inferior frontal and lateral temporal cortices (44).
Stress reduction effects have been attributed to acceptance training (64). Mindful breathing enhanced “decentering” from internal experiences, and reduced reactivity to repetitive thoughts (34). Improved self-control, emotion regulation, and stress reduction in smokers who practiced meditation were attributed to increased activity in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC), and other brain areas, as ACC/mPFC activity is diminished in smokers (29).
Mindfulness meditation significantly reduced neural activation in brain regions crucial for controlling nociceptive information (30). It is also associated with changes in learning and memory processes, perspective taking, and self-referential processing (31). In patients with generalized anxiety disorder, improvements were attributed to fronto-limbic regulation (32). MBSR also produced entrainment of chaotic activities in the brain and heart (33).
Immune system benefits may include reduced ratios of T1 pro-inflammatory to T2 anti-inflammatory lymphocytes (35). Increases in telomerase activity, a known marker of cellular aging and psychological risk, and reduced NFκB activity, a precursor to increased proinflammatory cytokines and circulating levels of C-reactive protein have been observed (36) (37) .
Adverse Reactions
Meditation is generally considered safe and effective, and few side effects have been reported. However, individuals who have experienced past traumas or abuse may respond negatively to some forms of meditation. Appropriate confidential screening may be needed to determine suitability of particular meditation practices in certain populations (52). In one survey, unwanted effects were transitory, and occurred more with focused attention meditation, when practicing longer than 20 minutes, and while being alone (53).
Case Reports
Psychosis: Following meditation (38) (39) and qigong practice (40) but some of these events occurred in concert with other issues including sleep loss, drug withdrawal, or pre-existing psychotic disorders.
Acute psychosis: In patients with schizophrenia after intensive meditation (41).
Qigong deviation syndrome: In patients following inappropriate qigong training, psychophysiological effects such as changes in heart rate, illusions, and pseudohallucinations (42).
Epilepsy: In a young woman after meditation (43).
