Answer
Some of the factors that affect the breathing rate are:
- While exercising or doing intense physical activity, the body requires more energy due to which the demand of oxygen increases. This increases the rate of breathing of the person.
- While sleeping and resting, the breathing rate decreases as the body requires less energy.
- Allergic reactions increase the rate of breathing as allergic reactions narrow the nasal passage leading to a demand for more oxygen.
- Stress and anxiety increases the breathing rate as the stress hormones trigger the body's fight or flight response.
