What factors are most likely to affect the breathing rate?

Various factors affect breathing rate-

• The body demands more oxygen supply during exercise; therefore, a person breathes more while exercising.
• The breathing rate becomes slow when a person is at rest or sleeping.
• Allergic reactions narrow the nasal passage leading to a demand for more oxygen supply. Hence, the breathing rate increases when a person has an allergic reaction.
• Anxiety or stress affects the nervous system and has a great impact on breathing. The breathing rate generally increases to cope up with the fight and flight response.
