What causes coughing, and how can it be resolved?

Generally, coughing may be caused by dry air, intense exercise, colds, bronchitis, heart failure, or other reasons. It can be treated under a doctor's guidance through general measures and medication. Specific analysis is as follows:

1. Dry Air

In dry environments, low humidity levels in the air can cause the throat and respiratory mucous membranes to become dehydrated, stimulating the cough reflex and triggering coughing. Using a humidifier to increase indoor humidity may help.

2. Intense Exercise

During vigorous physical activity, people tend to breathe faster, inhaling large amounts of cold or dry air, which can irritate the airways and lead to coughing. When exercising in cold or dry weather, it is advisable to breathe through the nose as much as possible.

3. Colds

Colds are usually caused by viral infections. The viruses irritate the respiratory mucosa, increasing secretions and triggering the cough reflex. Symptoms may include nasal congestion and runny nose. Under medical guidance, medications such as Lanqin Oral Liquid, Fenghan Ganmao Granules, or Compound Paracetamol and Amantadine Capsules may be used for treatment.

4. Bronchitis

Bronchitis can be caused by bacterial or viral infections, allergies, or other factors. Inflammation of the bronchi irritates the bronchial mucosa, leading to coughing and mucus production. Symptoms may include wheezing and chest pain. Patients should follow medical advice and take medications such as Levofloxacin Hydrochloride Tablets, Cefixime Capsules, or Compound Methoxyphenamine Capsules.

5. Heart Failure

Heart failure may result from infections, arrhythmias, or increased blood volume. It can lead to fluid accumulation in the lungs, stimulating the cough reflex and causing coughing. Symptoms may include shortness of breath and leg swelling. Under medical supervision, medications such as Enalapril Maleate Tablets, Valsartan Capsules, or Metoprolol Succinate Extended-Release Tablets may be prescribed.

To reduce the occurrence of coughing and other discomforts, it is important to maintain proper indoor humidity, avoid excessive airway irritation during intense exercise, and pay attention to overall health by preventing colds and respiratory infections.
