PRESSURE SUITS Meaning and
Definition
-
Pressure suits, also known as space suits or astronauts' suits, are specialized garments designed to protect humans from the hostile environment of space or other extreme conditions. These suits are essential when undertaking activities outside the protective environment of a spacecraft or in environments with decreased atmospheric pressure, such as high-altitude or deep-sea missions.
Typically made from multiple layers of durable, airtight materials, pressure suits aim to provide a controlled atmospheric environment around the body. The outermost layer usually consists of a robust fabric that can resist physical damage from sharp objects or micrometeoroids. The suit is designed to maintain a stable pressure and provide a constant supply of oxygen for breathing, compensating for the lack of atmospheric pressure in outer space or other inhospitable environments.
Pressure suits often incorporate a helmet or a clear bubble-like visor, ensuring visibility while preventing exposure to hazardous elements, such as vacuum, extreme temperatures, radiation, or foreign particles. They may also include gloves and boots to safeguard the extremities. Additional features like thermal regulation systems, communication devices, and waste management systems may be integrated into advanced suits to enhance comfort, safety, and function.
Pressure suits have been crucial for human space exploration, enabling astronauts to conduct extravehicular activities, repairs, and experiments outside of their spacecraft. Beyond space exploration, pressure suits find application in various industries, such as deep-sea diving, where the high-pressure marine environment requires similar protection and life-sustaining capabilities.
In summary, pressure suits refer to specialized garments that safeguard individuals from the impacts of extreme external conditions, such as high or low pressure, temperature variations, and the absence of breathable atmosphere. They play a vital role in enabling humans to withstand and function in environments that are otherwise inhospitable to life.

Etymology of PRESSURE SUITS
The term "pressure suits" is derived from the combination of the words "pressure" and "suits".
The word "pressure" originated from the Latin word "pressūra", which means "act of pressing". It entered the English language in the 14th century and refers to the force exerted on an object per unit area. In the context of pressure suits, it specifically refers to the pressure exerted by the atmosphere or other external factors.
The word "suits" comes from the Old French term "suite", which means "a following" or "sequence". It evolved into the Middle English word "sute" in the 14th century, referring to a set of matching clothes. Over time, it expanded to encompass a broader meaning of a set of garments worn together, often as a uniform or protective gear.
