The normal breathing rate for adults in a quiet state is about 16-20 breaths per minute. If it is more than 24 times per minute, it is tachypnea, and if it is less than 12 times per minute, it is hypopnea. During normal activities, emotional excitement, and excessive stress, the respiratory rate is likely to accelerate, which is a physiological acceleration of breathing. During sleep, there is a slowing down of the breathing rate, and these conditions do not require treatment. If the condition is caused by heart disease or respiratory disease, it can easily be accompanied by other symptoms. When there is a fever or hyperthyroidism, there is also an increase in the breathing rate, and when there is neurosis, there is also an effect on the breathing rate. In this case, the correct diagnosis needs to be made based on the symptoms and other tests, and active treatment with medication is required.
