[Introduction] Cold Dew is one of the twenty-four solar terms, it is the end of the month of You of the stems and branches and the beginning of the month of Xu. The Dou point to Wu, and the sun reaches Yellow Etiquette 195°, which is on the festival from October 7th to 9th of the Gregorian calendar every year. Cold dew is the season of late autumn. The temperature of cold dew drops a lot compared with the solar term of white dew and . Cold produces dew condenses, so it is called "cold dew". The dew turns from a hint of coolness in early autumn to a bit of cold "white dew is about to frost" in late autumn. It vividly reflects the continuous decline of temperatures. As the cold grows, everything gradually fades away.

From the perspective of traditional Chinese medicine, during the cold dew season, the yin and yang energy in nature begins to change, the yang energy gradually fades, and the yin energy gradually grows. At this time, the climate is dry, and people's sweat evaporates faster, so they often experience dry skin, increasing wrinkles, dry mouth and throat, dry cough and less phlegm, and even hair loss and constipation. Therefore, the focus of health preservation is to nourish yin and prevent dryness, moisten the lungs and benefit the stomach. The key points of health preservation are as follows:

1. No. To nourish the yin and prevent dryness, prevent colds: After cold dew, the weather will be dry, and it will be hot during the day and cool at night. Many people will have symptoms of respiratory infection , such as coughing and sore throat. In traditional Chinese medicine, it belongs to the " cool and dry " syndrome.

You can eat more foods such as sesame , tremella , radish , lotus root, lily and other foods that have the effects of nourishing yin and moistening dryness. Fruits are recommended, autumn pears, water chestnuts, bananas, etc.

2. Properly nourish the stomach and slowly nourish the spleen and stomach: When cold dew is cold, as the temperature gradually decreases, people naturally think of taking supplements, but at this time the function of the spleen and stomach has not yet fully adapted to the changes in the climate. Blindly eating fatty and sweet tonics can easily cause abnormal movement and transformation of the spleen and stomach, thus leading to the occurrence of diseases. At the same time, the weather in is getting colder in autumn. If you do not do a good job of protection, it is easy to cause gastrointestinal diseases or make the original stomach disease serious.

3. Exercise appropriately and maintain lung qi : exercise has different feelings and experiences throughout the year. The autumn is bright and the air is cool and the mist is in vain. If we insist on a more suitable physical exercise method, it will not only nourish our body's lung qi, but also improve the function of the organs.

Lying down early to adapt to the collection of yin essence and getting up early to adapt to the relaxation of yang energy can effectively avoid the formation of thrombosis.

The mental conditioning in the autumn season cannot be ignored. As the climate gradually becomes colder, the sun shines less, the wind rises and leaves fall, it often causes a feeling of desolation in some people's hearts, and there is an unstable mood and a sad and melancholy mood. Therefore, maintaining a good attitude, taking advantage of the situation, venting depression, and cultivating an optimistic and open-minded heart are one of the indispensable contents of health care.

5. Drink Chrysanthemum tea . Cold dew sesame: The ninth month of the lunar calendar when the cold dew arrives is the month of chrysanthemums.
