Episode 35 - Microgravity - Part 1

This episode kicks off our discussion of space physiology, focusing on the body’s initial responses to microgravity. We examine the headward fluid shift, changes in cardiovascular dynamics, and the impact on the vestibular system, which contributes to motion sickness and sensory disorientation. We also touch on how plasma volume reduction and cardiac remodeling affect astronaut performance and challenges upon re-entry to gravity.
