Respiratory practices refer to techniques and methods used to improve breathing and lung function. These practices can include exercises like diaphragmatic breathing and pursed-lip breathing, which help increase oxygen intake and promote relaxation. They are often recommended for individuals with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). In addition to exercises, respiratory practices may involve the use of devices like inhalers or nebulizers to deliver medication directly to the lungs. Maintaining good respiratory health also includes avoiding smoking, staying active, and practicing good hygiene to prevent infections.
