Sleep's influence on susceptibility to motion sickness in parabolic flights and virtual reality: An exploratory study

ObjectivesThe relationship between sleep and motion sickness (MS) remains underexplored. This study examined whether objective sleep parameters were related to susceptibility to motion sickness, elicited by different sensory conflicts.MethodsIn a cross-over design, twenty-six participants completed a virtual reality (VR) paradigm inducing cybersickness-provoking stimuli, while twenty of them underwent a parabolic...

Preliminary and exploratory; audiologists managing vestibular patients should note the possible sleep–motion sickness link as hypothesis-generating only — no practice change is warranted until confirmatory studies are available.

If sleep deprivation is confirmed as a modifiable risk factor for motion sickness susceptibility, it could inform pre-treatment counselling for patients undergoing vestibular rehabilitation or VR-based therapy.

1. 01Exploratory study examined objective sleep parameters as predictors of motion sickness susceptibility.
2. 02Two provocative environments tested: parabolic (microgravity) flights and virtual reality.
3. 03Published in Journal of Vestibular Research, directly relevant to vestibular audiology.
4. 04Exploratory design limits generalisability; findings should be treated as hypothesis-generating.
5. 05VR is increasingly used in vestibular rehab, making motion sickness tolerance clinically relevant.
