Leading scientists in space medicine published groundbreaking results regarding physiological changes in astronauts after orbital missions. The study, presented in the renowned scientific journal Journal of Applied Physiology on July 24, 2025, covers 13 space explorers.
The research team applied precise ultrasound techniques to track the condition of carotid and brachial arteries in the participants. Monitoring was performed at several key moments: before the space expedition, during the mission, a week after return, and periodically in the following 5 years.
The results reveal extremely encouraging facts. The structural parameters of blood vessels remained stable, and vascular functionality was fully restored. Inflammatory biomarkers, which initially increased during the mission, quickly returned to normal values.
Statistical data show a minimal increase in cardiovascular risk - from 2.6% to 4.6%. Experts emphasize that this increase is mainly due to natural age-related factors, not space conditions.
The scientific team's conclusion is categorically optimistic: long-term space expeditions do not pose a significant health risk to astronauts in terms of the arterial system. The study opens new horizons for future interplanetary missions.
