What causes cough during the day?

People's physical conditions vary from person to person, and different people react differently to different environments and things. Just like some people are allergic to pollen, they start to have nasal congestion and sneezing as soon as spring comes. And this won't happen to some people. So everyone has their own characteristics, and everyone is different. Some people cough during the day but not at night, which may be due to irritation from the environment during the day.

When you cough during the day, there are different reasons. It may be due to the stimulation of something. Gases, plants, and animals may all cause people to cough. In addition, teachers use a lot of chalk every day. Long-term inhalation of excessive dust can also cause coughing. So let’s take a look at the reasons for daytime coughing.

Dry cough is one of the common symptoms of clinical lung diseases. The causes are complex, the condition is stubborn, and the treatment is quite difficult. Recent studies have shown that almost all chronic persistent coughs can be diagnosed etiologically. Based on the onset time and syndromic characteristics of the dry cough, we use a combination of Chinese and Western medicine syndrome differentiation and disease differentiation to treat the cause, and have achieved satisfactory results. The following is a discussion on the causes, syndromes and treatments of dry cough.

Dryness evil invades the lungs and the lungs fail to descend

This type of cough is common in the early stages of infection and occurs more often in autumn each year. The lungs are a delicate organ that likes moisture and hates dryness, likes clearness and cannot tolerate cold or heat. Autumn is the dry season, and the dry evil invades the lung system, affecting the lung's function of dispersing and descending, and burning the lung fluid, thus causing this syndrome. The clinical manifestations are dry cough without sputum or little and sticky sputum, accompanied by dry throat, itchy throat, dry nose, thirst, red tongue with little fluid, thin white or thin yellow tongue coating, and floating and rapid pulse.

If the patient has prominent symptoms such as nasal congestion, aversion to wind, and itchy throat, you can add perilla leaves, cicada shells, white silkworm pupa, etc. to dispel wind, open the lungs and relieve cough.

Yin deficiency and lung dryness, dysfunction of clearing and purging

This type of syndrome is common in diseases such as chronic bronchitis, cough variant asthma, tuberculosis or lung cancer, and is clinically treated as a relevant examination to clarify the diagnosis. It can also be seen in patients who have been taking heat-clearing and detoxifying medicines or antibiotics for a long time, with depletion of lung yin, insufficient body fluid, yin deficiency and hyperactivity of fire, and endogenous virtual heat. The clinical manifestations are dry cough without sputum, which is mild during the day and severe at night and persists; or the sputum is small and sticky and difficult to cough up; or blood in the sputum, accompanied by dry mouth and throat, hot hands and feet, weight loss, night sweats, red tongue with little coating, and a thin and rapid pulse.

If the palms and soles are hot and there are night sweats, add Anemarrhena asphodeloides and Rehmannia glutinosa. If there is dry mouth and throat and blood in the sputum, add Phragmites australis and Imperata cylindrica as appropriate.

Liver depression, qi stagnation, fluid accumulation, phlegm coagulation

This type of syndrome is more common in laryngeal cough, with dry cough as the main symptom, or choking cough with little sputum, accompanied by itchy throat like ants crawling and discomfort caused by foreign sputum sticking to the throat. Coughing occurs when the throat itches, and the coughing is continuous and does not heal. There is dry mouth and tongue, fullness in the chest and flanks or even dull pain. It can be easily induced or aggravated by emotional distress. The tongue is pale red, the tongue coating is thin white (greasy), and the pulse is stringy.
