Yoga is not just a means to becoming more flexible. The World Health Organization (WHO) says there is growing research suggesting that practising yoga regularly may help with physical fitness, mental well-being, mobility and healthy ageing. But as yoga’s popularity grows, it is useful to understand what the research actually says—and what still needs to be studied.
What Did the Researchers Study?
Yoga is a meditative practice that originated in India over two thousand years ago. Today, it is a mind-body activity practised by hundreds of millions of people worldwide.
In a commentary published on 26 June 2026 to mark the 12th International Day of Yoga, WHO discusses the growing body of scientific evidence around yoga and its potential role in healthy ageing.
Rather than presenting just one new clinical trial, the WHO article brings together findings from a number of studies, including systematic reviews, meta-analyses and randomised controlled trials.
The important question is shifting to a more practical one: Can a flexible practice such as yoga help people preserve physical function and mental well-being as they age?
What Does the Evidence Say?
The WHO’s review of the evidence suggests yoga may be helpful in several areas.
Stress, Anxiety and Mood
Research cited by WHO includes systematic reviews and meta-analyses examining yoga and depression, anxiety, sleep quality and mood.
The findings suggest yoga may help support mental health. However, the results of individual studies can vary according to the population studied, the type of yoga used and how the programme was delivered.
Yoga should therefore be viewed as a potential complementary practice, not a replacement for professional mental health care when it is needed.
Physical Function: Flexibility and Strength
Yoga involves movement, balance and controlled positions that can challenge different aspects of physical fitness.
Research cited by WHO indicates improvements in functional fitness, including strength and flexibility. These abilities are especially important for older adults, as maintaining mobility helps people remain active and independent.
Importantly, yoga does not have to involve physically demanding poses. The practice can be adapted to a person’s mobility and physical ability.
Brain Health and Cognition
Another area of scientific interest is the possible relationship between yoga and brain health.
WHO highlights emerging evidence relating to memory and cognitive decline. However, this remains an evolving area of research, so the findings should be considered promising rather than proof that yoga can prevent dementia or other neurological conditions.
Cancer Survivor Support
WHO also references a large randomised trial presented at the 2026 meeting of the American Society of Clinical Oncology.
The trial examined a gentle, structured yoga programme for cancer survivors receiving standard survivorship care. WHO reported that the programme was associated with improvements in mood, anxiety and fatigue over one month.
This illustrates how yoga is studied as a complementary activity alongside conventional healthcare, rather than as a replacement for cancer treatment.
Can Yoga Help Back Pain?
WHO discusses one of the more established areas of research: chronic low back pain.
A randomised non-inferiority trial compared a yoga programme with physical therapy and education over 12 weeks in a diverse, low-income population. The study found yoga to be as effective as physical therapy for the outcomes measured, with benefits sustained at one year.
This does not mean yoga is necessarily appropriate for every person with back pain. It suggests that appropriately designed yoga programmes may be one option to consider as part of care for some people with chronic low back pain.
The key word is flexibility. The yoga programmes used in research are not necessarily the same as an unsupervised session or a generic online routine.
Why Healthy Ageing Is Important
The emphasis on healthy ageing reflects a wider global demographic shift.
As people live longer, maintaining independence and quality of life becomes increasingly important. Strength, balance, flexibility and mobility all contribute to a person’s ability to carry out everyday activities.
Yoga combines physical movement, breathing and mindfulness exercises. This combination may make it particularly suitable for people seeking an activity that addresses both physical and mental aspects of well-being.
This potential was highlighted by WHO’s 2026 International Day of Yoga theme, “Yoga for Healthy Ageing.”
Understanding Yoga in Its Traditional Context
Yoga originated in India as part of a broader philosophical and contemplative tradition. Many schools and approaches have developed over time, making modern yoga a broad and varied practice.
WHO’s scientific studies generally examine specific yoga programmes or components, such as movement, breathing, relaxation and mindfulness.
This distinction is significant.
The finding that a particular structured yoga programme was effective in a research study does not mean that every traditional claim about yoga has been scientifically proven.
The traditional context of yoga need not be discarded in favour of scientific research. Specific practices can be evaluated for their measurable effects while yoga’s wider historical and cultural importance is also recognised.
Why Flexibility May Be One of Yoga’s Strengths
Another reason yoga remains popular is that it can be adapted to different needs.
Older adults, people with different physical abilities and those with limited mobility may be able to participate through suitably modified practices.
Adapted yoga focusing on strength and mobility may make participation easier. However, adaptability does not mean there is no risk. People with health conditions or significant physical limitations should seek guidance from a suitably qualified professional.
The intensity and style of yoga should be appropriate to the individual’s abilities.
What Should Readers Take Away?
The growing body of evidence on yoga is promising, but important limitations remain.
First, the WHO article is a synthesis and commentary, not a single new clinical trial. The evidence comes from different populations and study designs.
Second, yoga is not one standardised intervention. Direct comparisons can be difficult because research studies may use different combinations of physical postures, breathing techniques, relaxation and mindfulness.
Third, promising results do not demonstrate that yoga can prevent or cure diseases.
Finally, these findings should not be interpreted as a reason to stop prescribed medicines or replace necessary medical treatment with yoga.
Yoga can be a useful complementary practice, but its role should be considered in the context of a person’s health needs and appropriate professional care.
Practical Takeaways
For those interested in yoga as part of a healthy lifestyle:
- Start at the right level. Choose activities suited to your age, fitness and mobility.
- Adapt the practice when needed. Yoga does not have to involve difficult poses.
- Think beyond flexibility. The practice can include balance, strength, mobility, breathing and relaxation.
- Use it as complementary support. Yoga should not automatically replace medical or psychological treatment.
- Seek professional guidance. If you have significant health conditions or physical limitations, consider instruction from a suitably qualified professional.
- Examine the evidence closely. What is true of one type of yoga programme is not necessarily true of every form of yoga.
The Importance of This Research
The growing scientific interest in yoga is part of a wider trend towards evidence-informed approaches to traditional medicine and mind-body practices.
The potential value of yoga for healthy ageing may lie less in any single dramatic health claim and more in the combination of movement, balance, strength, flexibility and mental well-being.
The WHO discussion also fits within its broader approach to traditional medicine, which calls for stronger evidence, appropriate standards and regulation alongside responsible integration into health systems.
Conclusion
Yoga is not a cure-all, but research is increasingly examining how it may support physical function, mental well-being and healthy ageing. Evidence cited by WHO suggests possible benefits in areas such as stress, mood, flexibility, strength, mobility and chronic low back pain.
The message for readers is straightforward: yoga may be a useful component of a healthy lifestyle, but its benefits must be considered in light of the available evidence, the specific practice being studied and each individual’s health needs.
