Breathing rate refers to the number of breaths a person takes in one minute. It is an important indicator of respiratory health and can vary based on factors such as age, activity level, and overall health. For adults, a normal breathing rate typically ranges from 12 to 20 breaths per minute at rest. Measuring breathing rate can help identify potential health issues. For instance, a significantly higher rate may indicate conditions like asthma or anxiety, while a lower rate could suggest sleep apnea or other respiratory problems. Monitoring breathing rate is a simple yet effective way to assess lung function.
