Microgravity removes the gravitational loading that anchors fluid distribution, mechanotransduction, vestibular calibration, and vascular homeostasis, exposing the human body to one of its most profound physiological challenges. Rather than producing isolated organ-specific changes, it induces a deeply interconnected, multi-system deconditioning response emerging from disrupted inter-organ communication....

No actionable change for clinical audiologists — this is a theoretical review of microgravity physiology with no direct application to earth-based audiology or vestibular practice at this time.
Understanding microgravity-induced vestibular deconditioning through a network physiology framework could inform future rehabilitation strategies for balance disorders affecting both astronauts and general patient populations.
- 01Review in Frontiers in Network Physiology examines multi-system deconditioning caused by weightlessness (microgravity).
- 02Vestibular system recalibration, fluid shifts, and vascular changes are among the systems discussed.
- 03Network physiology approach models how multiple body systems interact and fail together in microgravity.
- 04Relevant to space medicine but may have long-term implications for vestibular rehabilitation science.
- 05No clinical trial data; this is a theoretical/narrative review.
Microgravity causes measurable vestibular calibration changes as part of multi-system deconditioning.
