Discuss cardiovascular effects of microgravity exposure as well as mitigation strategies.
Microgravity exposure refers to the condition of experiencing very low levels of gravitational force, often in environments like outer space or during free-fall. The force of gravity is considerably reduced in microgravity, giving the sense of weightlessness. This happens because objects in free fall are constantly accelerating towards a larger celestial body (such as Earth), creating the sensation of weightlessness for individuals within the falling object.
The absence of normal gravitational forces in space has far-reaching consequences for the human body and physical objects. It can induce fluid changes, muscle and bone density loss, changes in cardiovascular function, and effects on numerous physiological systems. Scientists investigate microgravity to better understand its effects and devise measures to assist astronauts' health and well-being during extended space missions.
