Winter is the end, and all things are collected. The sunshine duration continued to shorten, and the lowest temperature gradually dropped to freezing point. At this time, the body needs to store enough energy to avoid the cold, which is not only beneficial for surviving the winter, but also has enough energy to welcome the spring of the following year. In traditional Chinese medicine, the kidney stores essence, and the kidney is the root of qi, which is the innate foundation. The essence stored in the kidneys here is the source of energy that maintains life, divided into kidney yin and kidney yang. The kidneys respond to winter, and the body's qi and blood will be hidden along with the "winter stored" qi. It can use the natural yang qi to fill the essence and collect kidney essence. Moderately increasing outdoor sunlight in winter can help stretch muscles and bones, and cultivate emotions. Traditional Chinese medicine guides gymnastics to harmonize body and mind, which can tonify deficiency and dispel evil. For example, practicing the sixth form of the Eight Section Brocade, "Climbing the feet with both hands to strengthen the kidney and waist", repeating the movements 6 times per group, 1-2 groups per day, is beneficial for unblocking the meridians and blood around the lumbar spine, consolidating kidney essence, and improving normal qi. According to the location of the kidney meridian, exercising the anal sphincter can enhance the strength of the pelvic floor muscles, improve urinary leakage and prolapse, prevent hemorrhoids, and help strengthen the kidney and consolidate the foundation. The deer play in Wuqinxi exercises the governor meridian through movements such as bending and turning the waist and back, which helps to nourish qi and kidneys, strengthen the waist and bones. Traditional gymnastics enthusiasts can persist in practicing in winter. The sudden drop in the temperature of the spirit of hiding is like a "downward threat" in winter. The cold evil, cold yin, and yang damage can cause blood stagnation and meridian contracture in the human body. It is a good season for stroke hemiplegia, myocardial infarction, influenza, rheumatic arthritis and other diseases. The human body needs to "hide the body and hide the spirit", and the focus is to resist wind and cold and prevent the onset. Hiding means protecting one's yang energy and preventing cold and injury to the body. The head is the meeting of all yang, and hiding the yang energy of the head is the top priority. Elderly people with excessive sweating during morning exercise and physical weakness should wear hats to ward off the wind and cold, avoid washing their hair in the morning, and prevent the invasion of cold and dampness when going out. Shoulders and feet are also important parts that need to be kept warm and hidden. For the prevention of childhood infections and pneumonia, even in winter, attention should be paid to indoor ventilation. The "neighbor ventilation" method of alternating people and space can be used, with each ventilation lasting 20-30 minutes to keep the air fresh. When going out, pay attention to keeping warm and protecting the mouth and nose. Diet can be combined with foods such as lilies and white radishes to moisten the lungs and prevent dryness. Especially keep your spleen yang hidden, and stop indulging in chilled drinks and cold fruits, such as cold watermelons, kiwifruit, pears, etc., to prevent phlegm and diarrhea. Elderly people and those with rheumatic arthritis, especially women, should ensure that their clothing is thick and comfortable. They can choose close fitting autumn pants, shoes, and socks to prevent cold waist and knee pain or menstrual cramps. For those who suffer from lower back pain, frequent urination, and enuresis, they can soak their feet in warm water at night, and use their thumb to press the Taixi acupoint (the midpoint of the line connecting the ankle and Achilles tendon) on both feet, for 2-3 minutes each time, 1-2 times a day, to help replenish kidney yang and strengthen the waist and knees. Zangshen refers to reducing excessive mental and physical exertion. After the beginning of winter, it is advisable to go to bed early to help conceal yang energy, nourish essence, and retain spirit. If one frequently works at night, it is easy to consume qi and blood, thereby damaging kidney essence. In traditional Chinese medicine, the kidney governs the marrow, and the brain is the sea of marrow. Protecting the brain and storing the spirit nourishes the kidney essence. Students and office workers should try to reduce staying up late and working overtime to overdraft, otherwise it can cause dizziness, blurred vision, emotional anxiety, forgetfulness, tinnitus, and even hair loss. For individuals with mental exhaustion, they can use fingertip compression or palm flexion to tap the top of their head on a daily basis
