Yoga For Health Anxiety And Somatic Symptoms: What Mr Iyengar, The Yoga Doctors And The Research Say

By Chris Lalor, Certified Senior Iyengar Yoga Teacher and Certified Yoga Therapist, and Dr Stuart McGill, Yoga Teacher, Flametree Yoga Darwin

The pain, the tiredness, the racing heart or the churning gut are real. The tests come back clear, and the worry does not go away. This guide brings together what Mr BKS Iyengar, Dr Timothy McCall and the research say about yoga, pranayama (yogic breathing), mindfulness and meditation for somatic symptoms: persistent physical symptoms without one clear medical cause, often called somatic symptom disorder or medically unexplained symptoms, and the health anxiety that so often comes with them.

Yoga for health anxiety and somatic symptoms: the short answer

Yes. Yoga, slow breathing and mindfulness are well worth trying when physical symptoms persist and worry about your health keeps coming back. Across 16 randomised trials, mindfulness courses eased persistent physical symptoms more than the comparison groups. In a trial of 74 adults with health anxiety, a year after a mindfulness course only 36% still had health anxiety, against 76% of those who did not take it. And when yoga was added to usual care for people with long-term pain that had no clear cause, pain, anxiety, low mood and other body symptoms all fell. Yoga and yogic breathing produce mindfulness, so the mindfulness trials are evidence for what yoga does. Trials that name yoga itself are still early, and none has yet tested Iyengar yoga. The common thread is learning to notice the body calmly, rather than scanning it in alarm.

What are somatic symptoms? They are real bodily symptoms, such as pain, tiredness, dizziness or stomach upsets, where the worry about them is out of proportion or the tests find no clear cause. “Somatic” simply means “of the body”.

The yoga studies here tested yoga in general, mostly in hospital clinics in India. No trial has yet tested Iyengar yoga for somatic symptoms or health anxiety. In our view as certified Iyengar teachers, precise, well-taught yoga with props, where attention goes to the alignment of the pose and the quality of the breath, is a strong way to build exactly the calm body awareness these trials point to. Why the kind of yoga matters.

The bottom line: five key moves for yoga with somatic symptoms and health worry

1. Take your symptoms seriously, and stop the endless checking. The symptoms are real. Repeated checking, searching and scanning tends to turn the volume up, not down.
2. Move the body regularly, with support. A yoga class several times a week, with props, gives the body steady, safe signals and builds strength and confidence.
3. Slow the out-breath. A long, soft out-breath tells the nervous system it is safe. Pranayama builds on this step by step.
4. Practise noticing without judging. Feel a sensation, name it, let it be, and come back to the breath. This is the skill the mindfulness trials taught.

Who was Mr BKS Iyengar? Iyengar yoga is the style we teach at Flametree. During the 20th century, Mr BKS Iyengar was the major teacher who codified traditional Indian yoga, through his seminal books and widespread teaching. He also pioneered the use of props, so poses can be adapted to almost any body, including a body that hurts or tires easily. His style is sometimes called modern classical yoga. This guide is part of our encyclopaedia of yoga for health conditions.

This guide in short

• Overall evidence: Strong. Best study (review of many trials): A 2025 network review of 74 studies with 8,277 adults living with bodily distress (persistent physical symptoms, including fibromyalgia and irritable bowel syndrome). Mindfulness and acceptance courses eased physical symptoms as well as talking therapy did, and eased anxiety and low mood more. Yoga and yogic breathing produce mindfulness, so this is evidence for what yoga does. A 2023 review of 16 randomised trials with 1,288 adults found the same.
• Mr BKS Iyengar: we have not found anything he wrote on somatic symptom disorder, but he wrote often about fear, pain and listening to the body, and his yoga trains steady attention on both.
• Dr Timothy McCall, an American medical doctor and yoga therapist who studied with Mr BKS Iyengar, author of Yoga as Medicine: somatoform disorders are no. 106 on his list of conditions helped by yoga, backed by three studies.
• The research: large reviews of mindfulness courses, for both physical symptoms and health anxiety, which count for yoga because yoga and yogic breathing produce mindfulness; early but positive yoga trials; one breathing pilot.
• Related guides: chronic pain, anxiety and anger, stress and burnout, chronic fatigue and fibromyalgia and digestion and IBS.

What are somatic symptoms and health anxiety?

Somatic means “of the body”. Somatic symptoms are physical symptoms: pain in the back, joints or head, tiredness, dizziness, a pounding heart, breathlessness, a churning gut. Sometimes they persist for months, and the tests do not find one clear medical cause. Doctors now use names such as somatic symptom disorder, bodily distress, persistent physical symptoms or medically unexplained symptoms. Dr McCall’s 2019 list uses the older name, somatoform disorders. Conditions such as irritable bowel syndrome (IBS), fibromyalgia and chronic fatigue syndrome are often grouped with them in the research, as functional disorders.

The symptoms are real. They are felt in the body, and they can be as disabling as any other illness. What the tests have not found is a single cause. Researchers now see a nervous system that has become very sensitive and very alert: signals from the body are turned up, and attention keeps going back to them. Stress, poor sleep, past illness, pain and worry can all feed this.

Health anxiety (once called hypochondria, now often illness anxiety) is persistent worry about having or getting a serious illness. A headache becomes a feared tumour, a skipped beat a feared heart attack. Checking, searching online and asking for reassurance bring relief for a moment, and then the worry returns. Many people have both: real physical symptoms, and worry about what they mean.

That 2025 review, by researchers from the University of Copenhagen and the University of Queensland, pooled 41 studies of 122,153 people in 23 countries and found 4.6% living with a somatoform disorder, and suggested these may be the second most burdensome mental health condition worldwide. In general practice the figure is higher: a 2026 review of primary care found about 16% of patients. In an Australian emergency department, people with the most body symptoms had used more than twice as much health care over the previous three and a half years. Read the 2025 review.

How symptoms and worry feed each other

“While we must recognize the existence and importance of pain, we must not glorify it.”

What Mr BKS Iyengar said

In short: we have not found anything Mr Iyengar wrote on somatoform disorders or hypochondria by name. But he wrote again and again about fear, about pain and about listening to the body, and his yoga trains the steady, calm attention that the research now points to.

He took pain seriously. He did not tell people it was imaginary; he said it must be recognised, and then worked with. He also saw how fear lives in the future: in Light on Life he wrote that in the present there is no fear. That is close to what mindfulness teachers say about health worry today: the feared illness lives in tomorrow, while the breath and the body are here now.

“In the future there is fear. In the present there is no fear.”

Mr Iyengar’s way into the mind was through the body. Each pose asks the student to feel exactly where the weight falls, which way the skin moves and how the breath behaves. That is careful noticing of the body, with a job to do. For someone used to scanning the body for danger, it can turn attention from alarm to interest. Props let a pose be held long enough for this, without strain. And he taught pranayama slowly, never forced, so the breath grows calm before it grows long.

“Fear and fatigue block the mind. Face both, then courage and confidence flow into you.”

What Dr Timothy McCall says

In short: somatoform disorders are no. 106 on Dr McCall’s June 2019 list of 117 health conditions helped by yoga. He backed the entry with three studies, all on this page: an open trial of yoga in 64 people with somatoform disorders, a 12-week yoga study in healthy women that lowered body symptoms, and a review of yoga for pain conditions with no clear physical cause.

Dr McCall also co-edited the medical textbook Principles and Practice of Yoga in Health Care (2016). Its chapter on other mental health conditions describes the yoga research on somatoform disorders as promising but early, and calls for larger, better controlled trials. Since then, a controlled yoga trial (2025) and two larger mindfulness reviews (2023 and 2025) have been published.

Other yoga voices

In short: Geeta S Iyengar, Mr Iyengar’s daughter and a senior teacher in her own right, spoke about how fear makes the body heavy. We have not found writing on somatoform disorders by Dr Krishna Raman, Dr Loren Fishman or Dr J. T. Shah in the material we hold.

“If my mind is heavy then I cannot raise my body up. Body becomes heavy if the mind is negative with fear.”

The yoga teams at India’s National Institute of Mental Health and Neurosciences (NIMHANS), who ran three of the trials below, built their programme for pain without a clear cause from traditional yoga texts and modern research, then had it checked by 18 experienced yoga therapists. When one team tested its programme, two poses (Triangle Pose and Locust Pose) were dropped as too hard for people in pain. That matches our own experience: for a body that hurts, the pose is adapted with props, not abandoned.

What the research shows on yoga for health anxiety and somatic symptoms

Here are the studies, grouped by what they tested. The yoga studies were yoga in general, not Iyengar yoga. Where a study tested a mindfulness course or breathing retraining instead, we say so. Why the difference between yoga and Iyengar yoga matters in the research.

Yoga trials

• Adding yoga to usual care eased pain, anxiety, low mood and other body symptoms, and improved physical quality of life. Gulati and others, 2025, India: a controlled trial of 70 adults with long-term pain with no clear physical cause (somatoform pain disorder). People chose their group, so it was not randomised; the assessors did not know who was in which group. Yoga ran for 24 weeks, and the yoga group also kept to their care plan better. Read the study.
• Pain fell from 7.2 to 2.9 out of 10 over 12 weeks of daily yoga. Sutar and others, 2016, NIMHANS, India: an open trial of 64 adults with somatoform disorders, 34 of whom completed 12 weeks; no comparison group. One of Dr McCall’s three references. Read the study.
• Body symptoms, anxiety, low mood, anger and tiredness all fell after 12 weeks of yoga. Yoshihara and others, 2014, Japan: 24 healthy women new to yoga, measured before and after; no comparison group. One of Dr McCall’s references. Read the study.

• Stress and everyday symptoms such as easy tiredness, stiff shoulders and poor sleep eased in ordinary yoga classes. Oka and others, 2021, Japan: 328 adults starting yoga classes, including 258 in poor health or with long-term illness, over 3 months. Minor discomforts were more common in those in poor health, none serious enough to stop. Read the study.
• Symptom severity fell after one month of a yoga programme designed for medically unexplained symptoms. Baboo and others, 2025, India: a programme of 34 practices, checked by 32 yoga experts, tried with 12 patients. An early feasibility study. Read the study.
• Pain fell after two weeks of a yoga programme for somatoform pain. Jha and others, 2021, India: a programme checked by 18 yoga experts, tried with 10 patients. An early feasibility study. Read the study.
• Reviews found yoga helps pain conditions that have no clear physical cause. Sutar and others, 2016: a review of yoga for functional pain (headache, neck and back pain, fibromyalgia, pelvic pain, IBS, chronic fatigue and somatoform pain), drawing on four meta-analyses. One of Dr McCall’s references. Read the study.

Guided deep relaxation (yoga nidra)

• Six months of guided deep relaxation eased pain, gut, heart and bladder symptoms. Rani and others, 2011, India: a randomised trial of 150 women with menstrual problems and body symptoms; 75 practised yoga nidra (a guided deep relaxation, lying down) as well as their medicine, 75 had medicine alone. Read the study.

Yoga nidra is a form of the deep, guided rest that ends every Iyengar class in Savasana (Corpse Pose). We do not teach it as a separate class, but the evidence on it counts for the rest our classes include.

Iyengar yoga

No trial has yet tested Iyengar yoga for somatic symptoms or health anxiety. Not yet studied is not the same as not working. Where Iyengar yoga has been tested, as in the Sydney pilot for falls in older people, it has done well, and in our view as certified Iyengar teachers its precise attention to the body suits this condition especially well.

Breathing and pranayama

• Five weeks of slow nasal breathing eased pain, gut and nerve-type symptoms, and the gains held at 3 months. Svenningsen and others, 2025, Norway: a pilot of 15 adults with medically unexplained symptoms and disordered breathing; weekly sessions of nasal breathing and slow, even (resonance) breathing. Breathing retraining, not pranayama by name; no comparison group. Read the study.

No trial has yet tested pranayama on its own in somatic symptom disorder or health anxiety. The yoga programmes above all included slow breathing. In our classes pranayama is taught step by step: watching the breath, then a slow out-breath, then staircase breath (Viloma) and ocean breath (Ujjayi) when your teacher judges you ready.

Mindfulness and meditation

The studies below tested mindfulness courses, most of them eight weeks long. They are evidence for what yoga does. Yoga and yogic breathing (pranayama) produce mindfulness: you cannot do a pose well without keeping your attention on it, here and now, and steady attention in the present is mindfulness. Breathing practice produces it too. In the film My Year Of Living Mindfully, Jon Kabat-Zinn, who created the best-known mindfulness course, defines mindfulness as “paying attention, on purpose, in the present moment, non-judgmentally”, and describes it as a state or a capacity that a whole family of practices builds. Yoga is one of the oldest of those practices, and in a Flametree class the mindfulness is there in every pose, often strongly. Yoga research is also hard to fund: the money comes from universities and governments, not from drug companies.

• Mindfulness and acceptance courses eased persistent physical symptoms more than comparison groups. Maas genannt Bermpohl and others, 2023: a review of 16 randomised trials with 1,288 adults with bodily distress (mostly fibromyalgia and IBS). Mindfulness-based stress reduction (MBSR), mindfulness-based cognitive therapy (MBCT) and acceptance and commitment therapy all did about as well as each other. Read the study.
• Mindfulness and acceptance courses eased physical symptoms as much as talking therapy, and eased anxiety and low mood more. Maas genannt Bermpohl and others, 2025: a network review of 74 studies with 8,277 adults with bodily distress, comparing these courses with cognitive behavioural therapy (CBT). Both beat the comparison groups for bodily distress, and the effects were partly kept at follow-up (PubMed 39993388). Read the study.
• Mindfulness therapies reduced symptom severity and pain and improved quality of life. Lakhan and Schofield, 2013: a review of 13 randomised trials in somatization and functional disorders; the clearest results were for IBS, and the structured eight-week courses did best. Read the study.

• Adding an eight-week mindfulness course to medicine meant fewer and milder physical symptoms, and less anxiety, low mood and stress. Zargar and others, 2021, Iran: a small but positive randomised trial of 37 adults with somatic symptom disorder. Read the study.
• A mindfulness course improved energy, social life and mental well-being in people who often visited their doctor with unexplained symptoms. van Ravesteijn and others, 2013, the Netherlands: a randomised trial of 125 adults; overall health ratings did not differ from enhanced usual care. Read the study.
• People with bodily distress improved faster with mindfulness therapy than with enhanced usual care, and the gains lasted 15 months. Fjorback and others, 2013, Denmark: a randomised trial of 119 adults; by 15 months the other group had caught up, so the two ended about the same. Read the study.

• Nurses who took an eight-week mindfulness meditation course reported less stress and fewer body symptoms, and two blood markers also fell. Alhawatmeh and others, 2026 (PubMed 41580885), a randomised trial of 102 nurses, compared with nurses who did no meditation. A third blood marker (TNF-alpha) did not change. Read the study.
• A parent mindfulness group did no better than a support group. Lassner and others, 2025 (PubMed 41237523), a pilot randomised trial of 31 families: a mindfulness group or a support group for parents of young people with pain that had no clear physical cause, alongside the young people’s own pain treatment. Both groups did well. We include it because not every trial is positive. Read the study.
• Take the overall picture with care. Boluda-Verdú and Catalá-López, 2025 (PubMed 40055062), a review of 27 reviews and 5 cost studies, found that the reviews of mindfulness and of talking therapy pointed to better symptoms, but most of the reviews were of low or critically low quality. Read the study.

Health anxiety and mindfulness

Again, these trials tested mindfulness courses, and they are evidence for what yoga does. Yoga and yogic breathing (pranayama) produce the same state of mindfulness, and doing any pose well asks for steady attention in the present.

• A year after a mindfulness course, only 36% still had health anxiety, against 76% of those who did not take it. McManus and others, 2012, England: a randomised trial of 74 adults with health anxiety; an eight-week MBCT course added to usual services. The more mindful people became, the more their health anxiety fell. Read the study.
• Health anxiety, illness worries and body symptoms all fell after an eight-week mindfulness course, and stayed lower 3 months later. Lovas and Barsky, 2010, United States: a pilot of 10 adults, no comparison group; no one dropped out. Read the study.
• Mindfulness was one of three ingredients linked with better results for health anxiety. Lai and others, 2026: a network review of 35 randomised trials with 3,263 adults. Mindfulness courses (MBCT) worked, and across all the therapies, those that included mindfulness did better. Read the study.

Talking therapy (CBT), not yoga

For completeness: cognitive behavioural therapy (CBT), a talking therapy, has the most trials for both somatic symptoms and health anxiety, and the reviews above found mindfulness courses did about as well. CBT and mindfulness are complementary: CBT works on the worrying thoughts and habits, while mindfulness, which yoga classes produce, trains calm attention to the body. This section only describes what was tested. A Cochrane review of 21 studies also found no trials at all of physical approaches such as movement or body work, which is where yoga sits. Read the Cochrane review. Not yet tested is not the same as does not work.

Practising well with somatic symptoms

Yoga for somatic symptoms works best gently and regularly. Some simple points, known from practice:

• Tell your teacher what you live with. Which symptoms come and go, what tires you, what you worry about. You do not need a diagnosis to be adapted for.
• Do less, more often. A steady practice beats a hard one followed by days of recovery.
• Use props freely. A chair, a bolster or a wall lets you stay in a pose long enough to settle.
• Take a sensation as information. In a stretch, notice it, breathe, and adjust with your teacher. Sharp pain means come out; a strong stretch can be explored.
• Do not use class to check your body. If you notice yourself scanning for symptoms, bring attention back to the pose and the out-breath.

“Where’s the time to hark back and talk and listen to your own body and mind?”

For women, and for men

Somatoform disorders are more common in women: 7.7% of women and 2.8% of men in the 2025 review. Many of the trials above were mostly women, and women already make up most of our classes.

Men are less likely to name worry, and more likely to carry it as tight shoulders, a sore back, a tight chest or a churning gut, and to keep pushing on. Men also do much less yoga than women. A yoga class is a practical way in: you work the body first, and the calm follows. Bring a mate or come alone, but give it 12 weeks.

Yoga, pranayama and mindfulness: how they work together

Most of the studies above tested a mindfulness course, a guided relaxation or breathing retraining. All of it counts for our classes. Mindfulness is a state of steady, present attention, and yoga poses and pranayama (yogic breathing) produce it: doing a pose well means focusing on it in the present, and slow, watched breathing does the same. The yoga programmes in the trials themselves joined poses with slow breathing and relaxation, and eight-week mindfulness courses include gentle yoga too, so in practice the two are not pulled apart.

We suggest coming to both a yoga class and a pranayama class. Mr Iyengar taught that asana (poses), pranayama and meditation are not divided, and in our experience the two together do more than either alone. See every class time. We trace the history and the links in Yoga And Mindfulness: Why The Mindfulness Research Points Back To Yoga And The Breath.

How this comes together in a Flametree class

Everything above points the same way, and it is how we teach yoga in Darwin and online. Flametree classes adapt poses with chairs and props, so a body that hurts or tires can still work steadily. Our LIVE online classes let you practise at home, with a teacher watching and guiding you.

• Tell your teacher about your condition. What you feel, when it comes, and what helps or makes it worse. A diagnosis is not needed.
• Standing poses with support: a chair or the wall, to build strength and confidence in the legs and back.
• Forward bends with the head supported: on a chair, a bolster or blocks, to quieten a busy mind.
• Gentle chest openers over a bolster: so the breath can move freely without effort.
• Pranayama step by step: watching the breath lying down first, then a slow out-breath, then staircase breath (Viloma) and ocean breath (Ujjayi) as your teacher judges you ready. Our pranayama classes teach it step by step.
• Rest to finish: every class ends with supported relaxation in Savasana.

See the timetable and book a class. Online classes run LIVE, so your teacher can see you and adjust your poses.

Yoga for health anxiety and somatic symptoms: questions people ask

Can yoga help health anxiety?

Yes, in the research so far. In a randomised trial of 74 adults with health anxiety, a year after an eight-week mindfulness course only 36% still had health anxiety, against 76% of those who did not take it, and a 2026 review of 35 trials linked mindfulness with better results. Yoga and yogic breathing produce that same calm, present attention, which is mindfulness, so these trials are evidence for what yoga does. No trial has yet tested Iyengar yoga for health anxiety. Read the anxiety guide.

Can yoga help somatic symptom disorder?

Yes. Adding yoga to usual care eased pain, anxiety, low mood and other body symptoms in a controlled trial of 70 adults with long-term pain without a clear physical cause, and a review of 16 trials found mindfulness courses eased persistent physical symptoms. Yoga produces mindfulness, so that counts too; the trials that name yoga itself are still early. Read the chronic pain guide.

Are medically unexplained symptoms all in the head?

No. The pain, tiredness, dizziness or gut trouble are real and felt in the body. What the tests have not found is a single cause. Researchers describe a nervous system that has become very sensitive and alert, so body signals are turned up. Yoga and slow breathing work with both the body and the nervous system.

Can yoga cure somatic symptom disorder or health anxiety?

No. What yoga can do is help: in studies, yoga, guided relaxation and mindfulness eased pain and body symptoms, lowered anxiety and low mood, and helped people worry less about their health.

Does yoga replace medical tests or care?

No. Yoga sits alongside your care, it does not replace it. Always follow the directions of any doctor you are consulting. Yoga helps with how you live with symptoms, and how calmly you notice your body.

What kind of breathing helps health anxiety?

A slow, soft out-breath, longer than the in-breath. It tells the nervous system it is safe. In a pilot of 15 adults with unexplained symptoms, five weeks of slow nasal breathing eased pain and gut symptoms. In our classes pranayama is taught step by step, from watching the breath to staircase breath (Viloma) and ocean breath (Ujjayi).

What if I notice symptoms during a yoga class?

Notice the sensation, name it, breathe out slowly and come back to the pose. A sharp pain means come out and adapt the pose with a prop; a strong stretch can be explored. Tell your teacher what you live with, so poses can be adapted from the start.

Is Iyengar yoga good for somatic symptoms?

No trial has tested Iyengar yoga for somatic symptoms yet. In our view as certified Iyengar teachers, its precise attention to the body, its props and its slow, unforced pranayama suit this condition especially well, because they turn attention from alarm to calm interest.

Can I do yoga for health anxiety online from Darwin or anywhere in Australia?

Yes. Flametree Yoga teaches Iyengar yoga LIVE online, as well as in Woolner and Coolalinga in Darwin. Flametree classes adapt poses with chairs and props, and your teacher can see you and adjust your poses. New students can begin with 2 free classes, then 10 at half price. Book a class
