Cabin pressurization refers to the process of maintaining a safe and comfortable pressure inside the cabin of an aircraft or spacecraft as it operates at high altitudes where the external atmospheric pressure is significantly lower than at sea level. The primary purpose of cabin pressurization is to ensure that passengers and crew can breathe comfortably and to prevent altitude-related health issues, such as hypoxia. At high altitudes, the air pressure is much lower, which means there is less oxygen available for breathing.
