Abstract
Iron is essential for cell respiration, muscle metabolism, and oxygen transport. Recent research has shown that simulated microgravity rapidly affects iron metabolism in men. However, its impact on women remains unclear. This study aims to compare iron metabolism alterations in both sexes exposed to 5 days of dry immersion. Our findings demonstrate that women, similarly to men, experience increased systemic iron availability and elevated serum hepcidin levels, indicative of iron misdistribution after short-term exposure to simulated microgravity.
