Vascular Aging in Space

Vascular aging in space refers to the changes that occur in blood vessels when astronauts spend extended periods in a microgravity environment, like on the International Space Station. In space, the lack of gravity can lead to fluid shifts in the body, affecting blood circulation and potentially causing blood vessels to become stiffer and less efficient. These changes can mimic aging effects on the cardiovascular system, raising concerns about astronauts' heart health and the long-term impact on their return to Earth. Understanding vascular aging in space is crucial for ensuring astronaut well-being during and after missions.
