Keep Warm: Don't "Autumn Freeze" Your Head or Feet
We often say "捂春冻秋" (捂春冻秋 - bundle up in spring, freeze in autumn). After autumn begins, don't immediately add more clothes just because the temperature drops slightly. You should add clothes gradually to keep warm and exercise your body's cold tolerance to enhance its ability to resist the cold.
After the "Bailu" (White Dew) solar term, the temperature difference between morning and evening begins to increase, and people will feel the atmosphere of autumn becoming more and more intense. Everyone believes that "autumn freezing" is good for health and is not in a hurry to wear thick clothes. But be careful, if you don't "autumn freeze" properly, you are very likely to catch a cold. Experts say that avoiding wearing thick clothes too early after "Bailu" is in line with the principles of health preservation, but no matter where you "autumn freeze," you should not freeze your head, feet, or navel.
From a health preservation perspective, the navel must never be exposed to the cold when the weather turns cool. Because there is no fat under the navel skin, it is close to rich nerve endings and plexuses, so it is particularly sensitive to external stimuli and can be easily invaded by cold pathogenic factors. Once the navel gets cold, abdominal pain and diarrhea are inevitable; if it is exposed to cold for a long time, urinary system diseases can also easily occur.
After "Bailu," it is best to wear a hat when going out. Use slightly hotter water than usual when washing your hair, and do not expose yourself to the wind when sweat appears on your forehead. This is because the head is the "convergence of all yang" in the human body and one of the parts with the most abundant yang energy. If this part gets cold, most of the body's yang energy will be lost. People with cardiovascular and cerebrovascular diseases, those with cold limbs, and those who are susceptible to wind-cold should be especially vigilant in this regard.
People should wear slightly thicker, loose, comfortable, and sweat-absorbent shoes and socks. Especially when taking a walk in the community in the morning and evening, you cannot just wear a pair of comfortable slippers as you normally would. If you get caught in the rain outdoors, be sure to soak your feet in hot water when you get home. In short, you should avoid your feet getting cold. There are 6 important meridians in the human body distributed in the feet. Once they get cold, it can trigger colds, bronchitis, indigestion, insomnia, and other diseases.

"Autumn Freezing" should end when the morning and evening temperatures are 10°C
In addition to the head, feet, and navel, properly "autumn freezing" other parts is indeed beneficial for preventing cold pathogenic factors from entering the body. However, "autumn freezing" refers to letting the skin be "beaten" and "exercised" by the external temperature. As for our internal organs, they cannot be "autumn frozen." Therefore, from the perspective of protecting the spleen and stomach, people who love to eat cold noodles, melons and fruits, and cold drinks should exercise moderation. Otherwise, it will make the spleen and stomach, which are already in a state of deficiency and cold, miserable. Everyone is reminded that when the outdoor morning and evening temperatures drop to around 10°C, "autumn freezing" should end, otherwise it will not only fail to prevent diseases but is also likely to invite illness.
Furthermore, diabetics, patients with cardiovascular diseases, patients with respiratory diseases, and patients with rheumatoid and rheumatoid arthritis are not suitable for "autumn freezing" at all. In addition, people over 60 years old should stay in a transitional temperature zone when going out, and only go outdoors after their body has gradually adapted to the environment. Also, it is not suitable for outdoor activities after a heavy meal or before 9 AM. This can effectively avoid acute attacks of cardiovascular and cerebrovascular diseases.
