Abstract
Space medicine necessitates a profound understanding of the physiological and psychological effects of extended space missions on astronauts. This review explores the efficacy of various microgravity simulation methods in understanding the cardiovascular system's responses in space-like conditions. While head down tilt tables and weight-reducing treadmills replicate certain aspects, they lack the comprehensive emulation of the psychological and visual stimuli inherent in space. Enter Virtual Reality (VR), an emerging technology offering immersive experiences resembling space environments. This narrative review delves into the potential applications of VR in simulating space conditions, particularly in analysing cardiovascular and stress hormone changes. Searching literature from 2015 to 2023 across several databases, this study analyses findings showcasing the effectiveness of -6° head-down tilt and AlterG systems in replicating microgravity conditions. Combining VR with these methods promises a more holistic approach, enhancing the fidelity of space simulation. The discussion emphasizes the potential of this amalgamation in understanding space-related health challenges, suggesting it as a crucial tool for future research and interventions aimed at ensuring the well-being of spacefarers. These microgravity analogues not only aid astronaut training but also serve as gateways for investigating life sustainability in space and engaging interdisciplinary exploration.
