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 (see the anxiety topic in the library):
- 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 a virtual reality system designed for healthcare environments and registered as a Class I Medical Device (base product) in EUDAMED and with INFARMED (Portugal), bearing the CE mark under 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, in a hospital or day hospital, where time and comfort matter.
When treatment is long and hard, giving the patient a better place to look has value of its own.

Frequently asked questions
Does virtual reality help during chemotherapy?
Oncology studies point that way: trials of virtual reality distraction during chemotherapy recorded less anxiety and better mood during sessions, and some report lower perceived nausea and fatigue. These are studies by independent researchers, not of RVer, and virtual reality does not replace treatment.
How is virtual reality used during chemotherapy sessions?
During the infusion, which can last hours, the patient puts on an immersive headset and is carried into a relaxing environment or an engaging experience. The distraction shifts attention away from the room, the IV, and the symptoms, making the wait less heavy.
Is it safe for cancer patients?
Virtual reality is a non-invasive, complementary approach, used under the supervision of the healthcare team and integrated into the care plan. It does not replace any medical treatment. Sessions are adapted to each patient's condition and comfort.
