Abstract: During space exploration, the human body is subjected to altered atmospheric environments
and gravity, exposure to radiation, sleep disturbance, and mental pressures; all these factors
are responsible for cardiovascular diseases. Under microgravity, the physiological changes related
to cardiovascular diseases are the cephalic fluid shift, dramatic reduction in central venous pressure,
changes in blood rheology and endothelial function, cerebrovascular abnormalities, headaches,
optic disc edema, intracranial hypertension, congestion of the jugular vein, facial swelling,
and loss of taste. Generally, five countermeasures are used to maintain cardiovascular health (during
and after space missions), including shielding, nutritional, medicinal, exercise, and artificial
gravity. This article concludes with how to reduce space missions' impact on cardiovascular health
with the help of various countermeasures.
