Meditation, the Immune System, and Cancer
What the Science Says
Meditation and mindfulness practices have become increasingly popular in healthcare research. Over the past two decades, scientists have explored how meditation may influence stress regulation, immune function, and wellbeing, particularly in people living with chronic illness.
A growing body of research suggests meditation can influence several biological systems connected to health. However, it’s important to be clear about what the evidence actually shows.
Meditation is not a treatment for cancer, but research suggests it may play a supportive role in improving mental wellbeing, stress regulation, and certain immune processes.
Stress, the Nervous System, and Immune Function
One of the key areas researchers study is the connection between stress and the immune system.
When we experience chronic stress, the sympathetic branch of the autonomic nervous system becomes more active. This “fight or flight” response increases stress hormones such as cortisol and adrenaline.
Over time, prolonged stress can influence immune function by:
increasing inflammatory signalling
altering immune cell activity
disrupting recovery and repair processes
This relationship between psychological state, the brain, and immune function is studied in a field called psychoneuroimmunology.
Meditation is often studied because it appears to help shift the nervous system toward parasympathetic activity, sometimes described as the body’s “rest and restore” state.
Research on Meditation and the Immune System
Several studies have examined how meditation may influence biological markers of immune activity.
A well-known review published in the Annals of the New York Academy of Sciences analysed randomized controlled trials investigating mindfulness meditation and immune outcomes.
The researchers found meditation may influence several biological processes, including:
reductions in inflammatory markers such as C-reactive protein (CRP)
changes in inflammatory gene expression
increases in telomerase activity, which is linked to cellular ageing
The authors also emphasised that research in this area is still developing and that results vary across studies.
Overall, the evidence suggests meditation may have modest but measurable effects on inflammation and immune signalling.
Meditation in Cancer Care
Meditation has been studied extensively as a supportive therapy for people undergoing cancer treatment.
Programs such as Mindfulness-Based Stress Reduction (MBSR) are frequently used in clinical research.
Studies consistently show improvements in:
anxiety and emotional distress
fatigue
sleep quality
overall quality of life
For example, research involving women with breast cancer found participants completing an MBSR programme showed improvements in certain immune measures alongside better psychological wellbeing.
While these findings are encouraging, meditation is considered a complementary therapy rather than a treatment for cancer itself.
Inflammation and Health
Scientists are increasingly interested in inflammation because it plays a role in many chronic conditions, including:
cardiovascular disease
metabolic disease
autoimmune disorders
some cancers
Some studies suggest meditation practices may influence inflammatory pathways such as NF-κB, which regulates how inflammatory signals are produced in the body.
These changes appear to occur partly through improvements in stress regulation and autonomic nervous system balance.
Expert Perspectives
Experts in mind-body medicine often describe meditation as a way to counteract the physiological effects of chronic stress.
Dr Herbert Benson of Harvard Medical School famously described the “relaxation response,” a physiological state that can occur during meditation and other calming practices. This response is associated with lower heart rate, reduced sympathetic nervous system activity, and improved stress regulation.
Researchers such as Dr David Black, who studies mindfulness and immune function, note that meditation may influence inflammatory biology and immune markers, though larger studies are still needed.
In clinical practice, meditation is widely recommended because it is safe, accessible, and can significantly improve wellbeing during difficult health challenges.
The Mind–Brain–Immune Connection
Modern research increasingly focuses on how the brain, nervous system, and immune system interact.
Meditation appears to influence several interconnected systems:
brain networks involved in attention and emotional regulation
the autonomic nervous system
stress hormone regulation
inflammatory signalling pathways
Because these systems constantly interact, practices that reduce chronic stress may help support better overall physiological regulation.
A Whole-Body Perspective on Health
Practices such as meditation, breathing exercises, and movement highlight how closely mental and physical health are connected.
Posture, breathing patterns, spinal movement, and nervous system regulation all interact. Many healthcare approaches now take a whole-body perspective, focusing on supporting the body’s ability to adapt and recover.
For people dealing with persistent tension, stress, or postural strain, working with a chiropractor in Islington may help address some of the physical factors that influence nervous system balance.
