Introduction
Rapid breathing rate may be caused by physiological factors or pathological conditions, such as hyperthyroidism, asthma, etc. Targeted treatment should be based on the specific underlying cause. Under normal circumstances, the human respiratory rate ranges from 16 to 18 breaths per minute. A rate above the normal range may occur after intense exercise or during states of stress and anxiety, which generally does not require special intervention.

I. Physiological Factors
Under normal circumstances, the human respiratory rate ranges from 16 to 18 breaths per minute. A rate exceeding this range may occur after intense physical activity or during states of stress and anxiety. Usually, no special treatment is required—simply adjusting one's emotional state allows for spontaneous recovery after a period of time.
II. Pathological Factors
1. Hyperthyroidism
In individuals with this condition, elevated levels of thyroid hormones lead to excessive sympathetic nervous system activation, resulting in tachycardia and subsequently increased respiratory rate. This is often accompanied by symptoms such as excessive sweating, insomnia, and weight loss. Treatment may include medications such as propranolol hydrochloride tablets, propylthiouracil tablets, or methimazole tablets, used under medical supervision.
2. Asthma
This condition impairs lung ventilation and gas exchange, leading to low blood oxygen levels and consequently rapid breathing. Treatment may involve inhaled medications such as beclomethasone/formoterol inhalation aerosol, budesonide powder for inhalation, or fluticasone propionate inhalation aerosol, as prescribed by a physician.
Besides the common causes mentioned above, other conditions such as pneumonia may also be responsible. Patients are advised to maintain a regular lifestyle and follow a light, balanced diet.
