Breathing spells, also known as respite or intervals where one catches their breath, can produce relief when one experiences stress or difficulty in respiration. The antonyms for breathing spells are mostly terms that have to do with challenges in breathing. Some examples include suffocation, constraint, strain, asphyxiation, apnea, and blockage. Suffocation is a term used to describe the sensation of being unable to breathe, while constraint refers to the restriction of airflow. Strain occurs when breathing involves too much effort, while asphyxiation and blockage involve a block of airflow or oxygen supply. Apnea means cessation of breathing. So while we enjoy breathing spells, it's necessary to be aware of the antonyms that denote conditions harmful to our respiratory system.
