What does inhaling mean?
Inhaling is the act of drawing air or another gas into the lungs and respiratory tract. It is the present participle of the verb “inhale” and appears both in ordinary descriptions of breathing and in formal warnings about inhaling smoke, dust, fumes, or chemical vapors. The expression “inhale deeply” is particularly familiar, suggesting a deliberate, full breath, whereas context can also give the word an undesirable or dangerous association when someone inhales a substance that should not enter the body. Inhaling is closely associated with the respiratory system and is often contrasted with exhaling, the process of expelling air from the lungs. The word is useful in medical, environmental, occupational-safety, and everyday contexts because it precisely identifies the inward phase of breathing or the intake of airborne substances.

"Workers were instructed to inhale vapors only under a properly ventilated system."
Every inhale brings oxygen in; every exhale sends carbon dioxide out, making breathing a precise exchange of gases rather than merely moving air.

Where does inhaling come from?
“Inhale” was borrowed into English from Latin inhalare, formed from in-, meaning “into,” and halare, meaning “to breathe.” The English verb developed the meaning of drawing air or vapor into the body, while related forms include “inhalation” and “inhaler.” Its opposite, “exhale,” was likewise formed with a Latin-derived prefix, ex-, meaning “out.”
