UHAB-1: Physiological responses to a 48-hour spaceflight analog mission underwater

Key Points

• Physiological responses were measured during a 48-hour underwater mission, highlighting adaptations to stress.
• The study found significant changes in stress markers, suggesting physiological adaptation occurs underwater.
• Observational analysis during an analog spaceflight mission assessed the impact of extreme conditions on human physiology.
• The findings support the need for further studies to understand adaptation mechanisms in extreme environments.
