Why is a pressurized spacesuit critical for human survival on the Martian surface?

Answer

It prevents bodily gases from expanding and protects against temperature and radiation

The Martian atmosphere is extremely thin and lacks the pressure required to maintain bodily fluids in a liquid state. Without a pressurized suit, gases within the human body would expand, leading to severe and life-threatening medical crises. Additionally, the suit acts as a vital barrier against the drastic temperature fluctuations, which can swing from 70 degrees Fahrenheit at the equator to negative 100 degrees Fahrenheit or lower, as well as providing necessary shielding from hazardous solar and cosmic radiation.
