Why is the air so dry in autumn?

Because in autumn, the temperature begins to decrease, the rainfall decreases, the air humidity decreases relatively, and the climate tends to be dry.

Autumn qi should be in the lungs, and the dry climate in autumn is easy to damage the lung yin, leading to dry mouth and throat, dry cough and less phlegm, dry skin, constipation and other symptoms, and even severe hemoptysis, so autumn health care should be prevented from dryness.

Autumn, in dry air, also means cool autumn. After people vent excessively in summer, all the tissues and systems of the body are in a state of relative water shortage. If people catch cold from the wind at this time, it will easily lead to a series of symptoms such as headache, stuffy nose, stomach pain and joint pain, and even make old diseases relapse or induce new diseases.

Old people and people with weak constitution have poor adaptability and tolerance to this change, so they should pay more attention to cold protection.

Extended data:

Autumn, including the following winter, is often the time when the indoor air is particularly dry. In this climate, people often feel thirsty and sore throat when they get up in the morning. Others will feel hot and dry skin and even dry eyes. Replenishing water is very important for relieving autumn dryness. But how to replenish this water is not just as simple as drinking more water.

In dry conditions, drinking water is also particular. The best time to replenish water is not to wait until you are thirsty, but to replenish water actively before and between meals. The water replenishing effect of pure water is often not the best, because it will quickly enter the blood through the digestive tract and then be discharged from the kidney, and it takes a short time to moisten the throat and digestive tract mucosa.

In contrast, water containing a small amount of carbohydrates (such as sugar, starch and various plant gums) is much better. If their osmotic pressure is lower than that of blood, they can replenish water.

Because carbohydrates are hydrophilic substances, they will absorb a lot of water molecules, delay the absorption of water and prevent water from being excreted quickly. In this way, the digestive tract mucosa will feel moist for more time, and the water will stay in the body for more time.
