Definition of the word breathing room

The phrase "breathing room" is an idiom that originated in the mid-19th century. The root word "breath" in this expression refers to the need for oxygen to sustain life, while "room" refers to the physical space required for movement and comfort. The expression came into use during a time when dwellings were becoming more crowded due to industrialization and urbanization. People needed a term to describe the need for space in their homes and workplaces where they could take a deep breath and relax, away from the confined and cramped surroundings. Initially, the term was used primarily in the context of architecture, where it referred to the physical dimensions of a room or building that allowed for adequate ventilation and space for normal breathing and movement. However, over time, the meaning of "breathing room" has expanded to encompass any situation that provides a sense of relief, freedom, and comfort, whether it be in a physical space or a metaphorical one.
