More puffing is usually referred to as heavy breathing or gasping for air, especially after physical exertion. The word panting can also be used to describe this phenomenon. Additional synonyms for more puffing include huffing and wheezing, although these terms may be indicative of a more serious respiratory condition. Other descriptive words for more puffing include heaving, laboring, and struggling for breath. These terms can apply to both people and animals, as any intense physical activity can result in heavy breathing and panting. It's important to pay attention to your body's signals and pace yourself during exercise to avoid excessive puffing and to make sure you're not overexerting yourself.
