What are the reasons for coughing when using air conditioning?

Generally, coughing when using air conditioning may be caused by dust irritation, colds, bronchitis, or other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Dust Irritation

This may occur if the air conditioner has not been cleaned regularly, leading to excessive dust accumulation inside the unit. When inhaled, this dust can irritate the throat's mucous membranes and trigger coughing. It is recommended to clean the air conditioner regularly to reduce dust exposure, which can help alleviate symptoms.

2. Cold

Coughing may result from respiratory mucosal irritation due to air conditioning after contracting a cold caused by pathogens such as adenovirus or rhinovirus. Symptoms may also include nasal congestion, sneezing, and coughing. Under a doctor’s guidance, patients may use antiviral oral liquids, Lianhua Qingwen capsules, Ganmao Ling granules, or similar medications for treatment.

3. Bronchitis

For individuals with bronchitis, non-specific inflammation of the tracheal and bronchial mucosa increases airway sensitivity. Exposure to cold air from air conditioning can then trigger coughing. Patients may follow medical advice to take medications such as azithromycin tablets, cefaclor tablets, or cefadroxil capsules to relieve symptoms.

In addition, bronchial asthma could also be a possible cause. It is recommended to identify the underlying cause and receive appropriate treatment. Maintaining healthy daily habits is important; avoid consuming spicy or irritating foods such as Sichuan pepper, chili peppers, and garlic, as these may hinder recovery.
