COPD: when breathlessness brings anxiety

Anyone who cares for people with chronic obstructive pulmonary disease (COPD) knows the scene: breathlessness starts, the person gets frightened, breathes faster and shallower, and the breathlessness gets worse. Fear and dyspnoea feed each other. Often, what the person describes as “I can't breathe” is already a mixture of the two.

This article is about that cycle, about what teams and pulmonary rehabilitation do to break it, and about what research says — and does not yet say — about virtual reality in this context.

The breathlessness–anxiety cycle

The literature describes it as a cycle: the sensation of breathlessness causes fear; fear speeds up breathing and increases muscle tension; rapid, shallow breathing, in someone whose lungs are already limited, makes the breathlessness worse. Over time, the person starts to feel afraid before they feel breathless — of the corridor, the stairs, the bath — and avoids effort. They move less, lose fitness, and the same effort costs more.

Two important notes:

• Anxiety in COPD is common and often goes unrecognised. The GOLD report (Global Initiative for Chronic Obstructive Lung Disease) treats anxiety and depression as common comorbidities of COPD that are frequently underdiagnosed. Prevalence estimates vary widely between studies, partly because symptoms overlap — which is why we give no figure here.
• How breathless someone is does not tell you how anxious they are. Some people with severe disease have little anxiety, and vice versa. It is worth asking rather than assuming.

What teams and pulmonary rehabilitation do

Pulmonary rehabilitation is one of the best-evidenced interventions in COPD, and the GOLD report recommends it. It includes supervised exercise, education and techniques for managing breathlessness, and there is evidence that it also improves symptoms of anxiety and depression. In Portugal, the DGS (Directorate-General of Health) has guidance on pulmonary rehabilitation programmes, including in primary care. Referral comes from the GP or respiratory specialist.

Day to day, the techniques physiotherapists and rehabilitation nurses teach are usually these (each person's plan is set by their own team):

• Pursed-lip breathing. Breathe in through the nose and out slowly through almost-closed lips, as if blowing on a candle without putting it out. It helps slow breathing down.
• Breathing control. Calm breathing, shoulders relaxed, without forcing deep breaths at the height of an episode.
• Recovery positions. Leaning forward while seated, forearms resting on the thighs or a table; or standing, leaning against a wall. These positions are recommended in rehabilitation leaflets from many health services.
• Blow as you go. Breathe out during the hardest part of a movement (standing up, climbing a step) instead of holding the breath.
• Pacing. Break tasks up, rest before running out of breath, plan the day.
• A plan for an episode. Knowing what to do, in what order, and when to call for help — including the prescribed reliever medication.

Anxiety itself is also assessed and treated. If the person lives in constant fear, avoids going out or has panic attacks, that is a matter for the doctor, not just for breathing techniques.

What research says about virtual reality in COPD

It is a young field, with small studies that differ a great deal from one another. Two examples set the tone.

A Polish randomised trial by Rutkowski and colleagues, published in 2021 in the Journal of Clinical Medicine, included 50 inpatients with COPD in pulmonary rehabilitation who had symptoms of anxiety or depression. Half received, on top of usual rehabilitation, ten 20-minute sessions of immersive virtual reality set in a virtual garden; the other half did autogenic training. The virtual reality group improved on anxiety, depression and stress scales, while the control group showed no significant change. The authors themselves point out the limits: a small sample, a single centre, no follow-up after discharge.

A systematic review and meta-analysis published in 2026 in the International Journal of COPD by Chen and colleagues pooled 10 randomised trials with 673 patients. It found reductions in anxiety and depression symptoms with virtual reality interventions, but with very high heterogeneity between studies (the trials used different content, doses and scales), few studies and geographic concentration. The authors' conclusion is cautious: a promising approach whose benefits need confirming in larger trials.

The honest reading: the evidence is preliminary. It suggests virtual reality may be a useful complement for some patients during rehabilitation, not that it treats anxiety in COPD. On how to read this kind of study, see scientific evidence.

Practical care in a session

If a team decides to use virtual reality with someone who has COPD, a few precautions matter more than the content:

• Seated, well supported, upright or leaning slightly forward. Lying flat, many people with COPD breathe worse; the lying-down mode exists for bedbound people, but here the clinical team decides the position.
• Short. A few minutes the first times. The thinking in session length and frequency applies even more here.
• Oxygen. If the person uses oxygen, it stays on as prescribed. Check that the headset straps do not dislodge or kink the nasal cannula or tubing. With a face mask or non-invasive ventilation, the headset does not fit well and, as a rule, the session does not go ahead.
• Start outside an episode. Do not use the headset to “calm down” someone in acute respiratory difficulty.
• Pause at the first sign. Faster breathing, use of the neck muscles, ever-shorter sentences, agitation, a change in colour, or oxygen saturation dropping below the target the team has set: take the headset off, follow the person's plan and call the professional in charge. If it is serious, call 112.
• Mind the covered face. For some breathless people, having something in front of their eyes feels smothering. Ask first and respect the answer.
• Hygiene. Clean face foam and cover between residents; see hygiene and safety.

Where RVer can fit in, and where it cannot

RVer is not a treatment for COPD or for anxiety, and it does not replace pulmonary rehabilitation, medication or an action plan. What it can offer someone who is stable, with the team alongside, is a calm moment: a few minutes seated on a beach or in a garden, which can help manage the anxiety of a day on the ward or an afternoon in the care home, and give something to talk about. At the team's discretion, it can accompany a spell of calm breathing the physiotherapist has already taught — without the content acting as therapist.

And there are people it does not suit: those who feel smothered by the headset, those in an unstable phase of the disease, those who simply don't want to. More on what virtual reality can and cannot do for anxiety in reducing anxiety with virtual reality.

In summary

• In COPD, breathlessness and anxiety feed each other in a cycle that leads to avoiding effort.
• Anxiety is common and often unrecognised; it is worth asking.
• Pulmonary rehabilitation, breathing techniques and recovery positions are the foundation, set by the team.
• Research on virtual reality in COPD is preliminary: small, highly heterogeneous studies.
• In a session: seated, short, oxygen kept on, never during an episode, pause at the first sign.
• It can be a calm moment; it is not treatment.
