World Heart Day is on 29 September. In 2026 the World Heart Federation continues its "Don't Miss a Beat" campaign, focused on recognising the symptoms of cardiovascular disease that go unnoticed.
We have nothing to say about the heart: virtual reality is not a cardiac intervention, and we make no claims of that kind. But the campaign's idea applies to something we know well: in a virtual reality session, the most important signs are the ones you do not see at first.
What the headset hides
In an ordinary conversation you can tell how someone is from their eyes. With a VR headset the eyes are covered. The person also cannot see who is with them, and may not realise they are allowed to interrupt.
That changes the job of whoever is supervising. You can no longer rely on eye contact, so you have to read everything else.
The signs that count
Breathing. Whether it speeds up, catches, or suddenly changes rhythm.
Hands. Hands gripping the sheet or the arm of the chair say more than any answer to "is everything all right?".
Posture. A body that curls up, pulls back, goes rigid.
Skin. Pallor, sweating, a flush that was not there before.
Silence. Someone who was talking and stops may be relaxed, or may be holding on.
None of these signs calls for a diagnosis. They call for one thing only: stop, take the headset off gently, and ask.
The rule is stop first
When in doubt, the session stops. Resuming is easy; rebuilding the trust of someone who felt unwell and was not listened to is much harder.
That is also why content is chosen by the clinical team. For someone with a heart condition, or any other condition the team considers relevant, some scenarios make more sense than others: calmer, slower, with no heights and no speed. The decision is clinical, case by case.
Not missing a beat
The campaign asks people not to ignore small signs. A session asks exactly the same: to be properly present in the room, looking at the person and not at the screen.
