A Lung Exerciser, often called an incentive spirometer, is used to improve lung capacity and strengthen breathing muscles. It usually involves inhaling slowly through a mouthpiece to raise a marker or balls inside the device.
It helps improve breathing by encouraging deep and controlled inhalation. This increases oxygen intake and prevents shallow breathing, which is common after surgery or during illness.
It is especially useful for people recovering from conditions like Chronic Obstructive Pulmonary Disease or after long periods of inactivity. Regular use helps clear mucus, expand lung capacity, and reduce the risk of infections. With consistent practice, a lung exerciser can make breathing easier, improve stamina, and support overall respiratory health.
