The word 'exhalation' is commonly used when talking about breathing. It refers to the act of breathing out, or expelling air from the lungs. It is often used in medical or scientific contexts, but can also be used in everyday conversation when discussing things like breathing exercises or meditation. So, if you are talking about taking deep breaths and letting them out slowly, you might use the word 'exhalation' to describe the breathing out part of the process.
