pressure suit

A pressure suit is specialized clothing designed to maintain a stable outward pressure on the body in environments where the atmosphere is insufficient or absent, such as in space or high-altitude flight. It prevents bodily fluids from boiling and protects against the vacuum’s effects by ensuring the internal pressure of the body remains balanced with the external environment. The suit also supplies oxygen, removes waste gases, and often includes systems for temperature regulation. Essentially, it creates a safe, controlled environment around the wearer’s body when external conditions cannot support normal life functions.
