Great Cold Health Preservation: Avoiding Cold, Storing Yang to Nurture Vitality, Quietly Awaiting the Sprouting of Spring Energy
The Collection of Lunar Seventy-Two Pentads states: "Great Cold, mid-twelfth month. Explanation as before (Minor Cold)." As the final station of the twenty-four solar terms, Great Cold is the time of year when yin-cold is at its peak and yang qi is stored deepest. All things between heaven and earth are in a state of closure and dormancy. Traditional Chinese Medicine (TCM) holds that the core of health preservation during this season lies in "conforming to heaven and responding to the seasons" – externally avoiding severe cold to protect yang qi, internally nurturing righteous qi to solidify the foundation, accumulating energy within this closure, and quietly awaiting the growth and development of yang qi in the coming spring. This is the health preservation wisdom of "nurturing vitality during Great Cold to avoid illness in spring."
"Cold is a yin pathogen, easily damaging yang qi." The cold pathogen during Great Cold most easily invades the human body. If care is improper, leading to impaired yang qi and deficient righteous qi, it can not only cause immediate discomforts like aversion to cold, colds, and joint pain but may also result in insufficient yang qi growth in the coming spring, potentially triggering issues like dizziness, fatigue, and weak spleen-stomach function. Therefore, Great Cold health preservation hinges on two aspects: "avoiding cold" and "nurturing vitality." These two complement each other to solidify the foundation of health.
I. Daily Life: Avoiding Cold, Storing Yang and Keeping Warm, Not Disturbing the State of Closure
During Great Cold, the body's yang qi is like a seed buried deep underground, requiring quiet nurturing and should not be recklessly dissipated. The core of daily life regulation is "storage," which involves both avoiding external cold invasion and reducing the consumption of yang qi, conforming to the nature of heaven and earth's closure.
TCM emphasizes "rising with the sunrise and resting with the sunset." During Great Cold, it is even more important to "sleep early and rise late." Sleeping early conforms to the storage of yang qi, avoiding cold pathogen entry at night; rising late allows one to wait for the faint morning light and gradual growth of yang qi, reducing the stimulation of morning chill on the body. This is especially suitable for the elderly, children, and those with cold or deficient constitutions. Upon waking, do not get up abruptly. Instead, keep eyes closed and rest the spirit briefly in bed, move the limbs gently, then get out of bed slowly. This prevents dizziness and palpitations caused by the stagnation of qi and blood due to cold.
Avoiding cold requires attention to both "external defense" and "internal protection." When going out, ensure thorough warmth for the head, neck, waist, knees, feet, and other areas. TCM says "the head is the meeting point of all yang," "the waist is the residence of the kidneys," and "cold arises from the feet." These areas are key points where yang qi gathers and cold pathogens easily invade. Wearing hats, scarves, thick socks, and knee protectors, and avoiding direct drafts is recommended. Indoor warmth should be moderate, with room temperature ideally between 18-22°C (64-72°F). Do not overly rely on heaters or floor heating, as excessive indoor-outdoor temperature differences can damage yang qi. Additionally, open windows for ventilation for 15-20 minutes daily to maintain air circulation and prevent the accumulation of dampness and turbidity indoors.
Furthermore, during Great Cold, reduce intense physical activity and avoid sweating profusely. TCM believes "sweat is the fluid of the heart." Profuse sweating consumes yang qi and body fluids, going against the principle of closure. Choose gentle exercises like Ba Duan Jin, Tai Chi, or indoor slow walking, aiming for a state where the body feels slightly warm. This can promote blood circulation, resist cold pathogens, and not deplete yang qi, aiding its storage.
II. Diet for Nourishing Vitality: Warming and Supplementing to Disperse Cold, Protecting the Spleen and Stomach
The Great Cold diet follows the principle of "warm supplementation without causing dryness, and consolidating the foundation to cultivate vitality." It should be adjusted according to individual constitution, both to resist cold pathogens and to avoid excessive consumption of warming foods, which may generate internal heat and consume yin fluids. TCM teaches that "the spleen and stomach are the acquired foundation, the source of qi and blood production." To nurture vitality during Great Cold, one must first nurture the spleen and stomach. Only with robust spleen-stomach function can they transform food and fluids, generate yang qi, and nourish the entire body.
Those with cold or deficient constitutions can appropriately consume warming and supplementing foods like lamb, beef, and chicken, paired with cold-dispersing seasonings like ginger, Sichuan pepper, and star anise. Examples include Dang Gui Ginger Lamb Soup or Huang Qi Stewed Chicken. These can warm the middle, disperse cold, supplement qi and blood, nourish yang qi, and alleviate symptoms like aversion to cold, cold hands and feet, and sallow complexion. Additionally, moderate intake of nuts and dried fruits like chestnuts, walnuts, and longan is suitable. Chestnuts can tonify the kidneys and spleen, warm the middle to stop diarrhea; walnuts tonify kidneys and benefit the brain, warm lungs and moisten intestines; longan supplements heart and spleen, nourishes blood and calms the spirit.
Those with heat-biased constitutions or prone to internal heat should avoid excessive consumption of pungent, warming foods. They can pair warming and supplementing ingredients with heat-clearing and dryness-moistening items like white radish, napa cabbage, lily bulbs, and snow fungus. This can balance the warming nature while nourishing yin and moistening dryness, preventing issues like dry mouth and throat, sore throat, and constipation. For example, adding white radish when stewing lamb can cut greasiness, clear heat, promote fluid production, and aid digestion, balancing warming supplementation with moistening dryness.
Special attention is needed: During Great Cold, spleen-stomach function is relatively weak. Avoid consuming raw, cold, cooling, or greasy foods like icy drinks, raw seafood, and fried foods, as these can damage spleen-stomach yang qi, leading to indigestion, bloating, or diarrhea. Also, practice eating smaller, more frequent meals, avoiding overeating to lessen the burden on the spleen and stomach, aiding qi and blood production, and consolidating righteous qi.
III. Emotional Regulation: Calming the Mind and Spirit, Avoiding Restlessness
TCM believes "emotions originate from the five zang organs." The pervasive yin-cold of Great Cold can easily lead to low spirits, irritability, and anxiety. Negative emotions disturb yang qi, consume righteous qi, and affect the work of closure. Therefore, emotional regulation is also a crucial part of nurturing vitality during Great Cold. The core lies in "calming the mind and soothing the spirit," maintaining inner peace, avoiding excessive thinking, and restlessness.
Adjust emotions through meditation, mindfulness, or listening to soothing music to help the heart-spirit settle into tranquility and support yang qi storage. On sunny afternoons, go outdoors to sunbathe. TCM considers sunlight the essence of natural yang qi. Sunbathing can supplement the body's yang qi, dispel internal cold, and simultaneously relieve low mood, promoting physical and mental comfort. When sunbathing, focus on the back (the Governor Vessel is the 'sea of yang channels,' and the back has the most abundant yang qi), avoiding strong light directly in the eyes.
Avoid excessive worry, anxiety, or dramatic emotional swings. Especially avoid letting year-end trivialities disturb the heart-spirit. TCM teaches "worry damages the spleen" and "anger damages the liver." Excessive worry impairs spleen-stomach function, affecting qi and blood generation. Great anger can cause liver qi stagnation, disturbing yang qi and going against the nature of closure. Distract attention by communicating with family and friends or cultivating hobbies, maintaining an open-minded mood to adapt to seasonal changes with a peaceful mindset.
IV. Meridian Care: Warming and Unblocking Qi and Blood, Aiding Yang Storage
During Great Cold, cold pathogens easily stagnate qi and blood, leading to meridian blockage and causing problems like joint pain and limb numbness. Through meridian care, one can warm and unblock qi and blood, disperse cold and eliminate dampness, while also nourishing the zang-fu organs and protecting yang qi, forming a synergistic effect with daily life and dietary care.
Moxibustion is the most suitable meridian care method for Great Cold. Moxibustion can warm and unblock meridians, supplement yang, and disperse cold. Targeted moxibustion on the following acupoints can effectively enhance vitality-nurturing results:
Guanyuan (CV4): Located on the lower abdomen, 3 cun (approximately 3 finger-widths) below the navel. It is where original qi converges. Moxibustion on Guanyuan can warm and supplement original qi, protect kidney yang, and enhance the body's ability to resist cold.
Zusanli (ST36): Located on the outer side of the lower leg, 3 cun below the knee depression (on the tibialis anterior muscle). It is the He-Sea point of the stomach meridian. Moxibustion on Zusanli can strengthen the spleen and harmonize the stomach, boost qi and nourish blood, solidifying the acquired foundation.
Shenshu (BL23): Located on the lower back, 1.5 cun lateral to the spinous process of the second lumbar vertebra. Moxibustion on Shenshu can tonify the kidneys, warm yang, disperse cold, and eliminate dampness, alleviating symptoms like soreness and weakness of the lower back and knees, and aversion to cold.
During moxibustion, aim for a local sensation of warmth and slight skin redness. Each session can last 15-20 minutes, 2-3 times per week. Those with cold/deficient constitutions can appropriately increase frequency; those with yin deficiency and fire excess should use caution.
Besides moxibustion, massage can also promote qi and blood circulation. Massage Yongquan (KI1) (located in the depression of the sole, at the junction of the anterior and middle third of the foot) daily before bed. Press with the thumb for 3-5 minutes until the sole feels warm. This can tonify kidney essence, warm and unblock meridians, and relieve coldness in the lower limbs. Massaging Taichong (LR3) (located on the dorsum of the foot, in the depression between the first and second metatarsal bones) can soothe liver qi and regulate blood, improving irritability and liver qi stagnation.
Conclusion: Nurturing Vitality in Great Cold, Spring Energy Arises Naturally
Though Great Cold is harsh, it is the prelude to the growth of yang qi, much like the deepest part of the night heralds the impending dawn. TCM health preservation is never about going against the current, but about conforming to heaven and responding to the seasons. In the coldest time, prioritize avoiding cold and protecting yang, root in nurturing vitality and consolidating the foundation, allowing the body to resonate with heaven and earth, accumulating energy within closure.
Do not be disturbed by the severe cold, nor rush for quick results. Simply adhere to the principles of regular daily routine, dietary moderation, and emotional balance. Guard against external cold pathogens and internally nurture righteous qi, and you can attain winter wellness. After Great Cold passes, Beginning of Spring arrives. The stored yang qi ascends following the natural tendency, filling the body with vitality and vigor. This is the ultimate meaning of Great Cold health preservation – using the substance of winter storage to cultivate the posture of spring growth, letting the year's health begin with the precipitation and care at year's end.
