VRSENSORY DESIGNSTRESS REDUCTION

Olfactory Stimuli in VR

2025 · Peer-reviewed · Yasmin Elsaddik


Overview

I've always been fascinated by how a single scent can shift your entire mood in seconds, so we set out to test whether that effect could be recreated inside a virtual environment.

Scent is the most underrated sense in immersive design.

What I studied

We ran a controlled experiment with 30 participants to test whether adding scent to a VR environment reduced stress more effectively than visuals alone. We measured physiological and self-reported stress responses across different sensory conditions inside an immersive virtual space.

What I found

Participants in the scent-enhanced VR condition showed meaningfully stronger stress reduction than those in the visual-only condition. It suggests that smell is the most powerful lever for making virtual environments feel genuinely calming.
