Virtual reality for better sleep: what the studies say about VR and insomnia

Sleeping badly is one of the most common health complaints — and one of the most searched online. Among the non-pharmacological approaches research has explored for sleep, relaxation-based virtual reality is one of the newest. It is worth looking at what the studies show, without hype or automatic scepticism.

The plausible mechanism: relaxing before sleep

Difficulty falling asleep is often tied to a state of physiological arousal — a racing mind, a tense body. Any approach that helps lower that arousal creates more favourable conditions for sleep.

This is where relaxation-based virtual reality comes in: calm immersive environments, sometimes combined with guided breathing or biofeedback, aim to induce a state of calm before bed. It is not a sedative — it is a relaxation aid.

What the studies say

The research is recent, but clinical trials already exist:

• A randomized controlled trial published in the Journal of Medical Internet Research (2025), with 118 participants over 4 weeks, observed improvements in sleep quality measured by the PSQI (in the VR group, the global score fell from 9.70 to 7.20), alongside reduced depressive and anxiety symptoms.
• A randomized trial published in Sleep Medicine (2024) tested relaxation VR used at home, in the evening, for 6 weeks, in patients with chronic insomnia, with associated improvements in sleep quality.

The signal is consistent: immersive relaxation environments can support sleep. But the evidence is still early, with small samples and few long-term studies.

The limits it is honest to mention

• The literature acknowledges that evidence on VR for sleep disorders is limited and still inconclusive.
• Persistent insomnia has a well-established first-line approach — cognitive behavioural therapy for insomnia (CBT-I) — that VR does not replace.
• The effect comes from relaxation, not from any "magic" property of the technology.

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. Its focus is relaxation and comfort through immersion — used under the supervision of professionals and with no collection of patient clinical data.

The honest reading of the evidence is also the most useful: relaxation-based virtual reality is a promising aid for sleep, not a substitute for what is already proven.
