Cough in autumn. What is the reason?

The summer heat has dissipated, and when autumn comes, the temperature begins to drop slowly. Do you suddenly feel thirsty, especially dry throat and cough? These are all due to the evil of dryness.

In autumn, the weather converges, the temperature drops, the precipitation in most areas decreases, and the whole nature loses moisture, so "dryness" becomes the main gas in autumn. Traditional Chinese medicine believes that the lungs are "delicate and dirty", and they like dampness but hate dryness. Moreover, our human body relies on the lungs to breathe, and dry air can easily enter the body through our nose and mouth, damaging the normal physiological function of the lungs.

In autumn, when the air is dry and the air humidity is low, people will feel thirsty, and constipation, cough and asthma, some digestive tract diseases and some common diseases caused by autumn dryness also begin to increase. This kind of cough is mostly dry cough in autumn. The lungs of human body like humid environment and are sensitive to dryness. Many people can't help coughing twice even if they are not sick this season.

In autumn, people's respiratory immunity decreases, and the temperature difference between day and night is large. The cold at night will reduce their immunity after stimulating the respiratory mucosa. Bacteria can easily invade the respiratory tract, causing mucosal congestion and edema, increased secretion, sneezing, stuffy nose, runny nose, expectoration and other discomfort.

Dryness dominates autumn, and dryness is easy to hurt the lungs. Dryness mostly enters through the nose and mouth and invades the lungs. In addition, autumn dryness consumes yin and damages yang, making human pores open and vulnerable to cold. Some diseases are easy to recur or worsen in dry climate in autumn, such as bronchiectasis and tuberculosis. At this time, cough, expectoration and hemoptysis are aggravated.

Some people think that cough may be caused by the change of weather, but in fact, autumn cough is mainly dry cough, commonly known as "autumn dry cough". Dry cough in autumn is also divided into warm dryness and cool dryness. Generally, the Mid-Autumn Festival is the boundary, and there is residual heat before the Mid-Autumn Festival, so it is more common in warm and dry; After the Mid-Autumn Festival, the autumn wind is getting tighter and the cold is getting heavier, so it is often cool and dry.
