Virtual reality during chemotherapy: distraction and comfort through cancer treatment
Chemotherapy treats the body but wears down the mind: the waiting, the anxiety, the nausea. Virtual reality carries the patient somewhere else during the session.
Chemotherapy treats the body, but it carries a cost beyond the physical. Sessions are long — sometimes several hours hooked to an IV — threaded with anxiety, anticipation, and symptoms like nausea and fatigue. For many patients, the psychological strain of the wait is a real part of the experience.
Virtual reality offers something simple but valuable in this context: a way to mentally leave the treatment room without leaving the chair.
The mechanism: occupy attention, ease the wait
During a long infusion, attention tends to fix on the room, the IV, and every bodily sensation — and that focus amplifies anxiety and discomfort. Immersive virtual reality engages vision and hearing, carrying the patient into a calm environment or an absorbing experience.
With attention elsewhere, there is less mental room for anticipatory anxiety and for symptom vigilance. The treatment time passes differently — less like a wait, more like a pause.
What the evidence says
Oncology is one of the areas where VR distraction has been drawing growing attention, with encouraging results:
- Trials with patients in chemotherapy show reductions in anxiety and improvements in mood during sessions using virtual reality.
- Several studies point to lower perceived nausea and fatigue when the session takes place with immersive distraction.
- VR is particularly well suited because the chemotherapy experience combines long waiting time with high emotional load — exactly the ground where immersive distraction is most useful.
It does not change the treatment, but it can change how the patient experiences it — and across many cycles, that counts.
Why it matters, beyond the session
- Better experience across many cycles — people in chemotherapy repeat sessions over weeks or months; making each one more tolerable has a cumulative effect.
- Less anticipatory anxiety — a lighter experience can reduce the dread of the sessions to come.
- A non-pharmacological approach — useful as a complement, without adding medication.
Important note: virtual reality is a complementary, non-pharmacological approach. It does not replace chemotherapy, antiemetic medication, assessment, or the decisions of healthcare professionals, and is always used under their supervision and integrated into the care plan.

The role of RVer
RVer is an immersive virtual reality therapy system designed for healthcare environments and certified as a Class I Medical Device by Infarmed, in compliance with the European regulation MDR 2017/745. It is built to be simple for the team to start, comfortable for the patient, and with no collection of patient clinical data — well suited to a treatment room where time and comfort matter.
When treatment is long and hard, giving the patient a better place to look has value of its own.
