Do you also suffer from this troubling issue: even though you wear more layers than others, your hands and feet feel like blocks of ice and never warm up regardless of the season? Especially in winter, when you go to bed at night, your feet are freezing and you can't warm the bed up for the longest time—you may even fear the air conditioning in summer because it makes your palms cold. What exactly is going on? Is it a constitutional issue, or is your body sending some kind of signal?
From the perspective of traditional Chinese medicine (TCM), cold hands and feet that never warm up through the seasons are usually related to "yang qi deficiency" or "poor circulation of qi and blood." The TCM classic Huangdi Neijing (The Yellow Emperor's Inner Canon) states: "Yang qi is like the sun in the sky; if it loses its place, life will be cut short and fail to flourish." This means that the body's yang qi is like the sun in the sky—it is the fundamental driving force of life activities. If yang qi is weak or its movement is impaired, it not only fails to warm the extremities but also affects overall vitality. Yang qi in the human body performs three major functions: warming and nourishing, transformation and transportation (qi transformation), and defense against external pathogens. The warming function keeps the limbs and bones at a constant temperature; the transformation function promotes the distribution of body fluids, essence, and blood; and the defense function resists invasion by external pathogens. When yang qi is deficient, its warming power cannot reach the four extremities, resulting in cold hands and feet. If qi movement is blocked and blood vessels are not smooth, then even if yang qi itself is not deficient, qi and blood cannot reach the extremities smoothly, likewise manifesting as cold limbs. The Suwen · Yangming Mai Jie Pian also states that "the four limbs are the root of all yang," indicating that the temperature of the limbs directly reflects the abundance or decline of yang qi in the body and whether its pathways of movement are unobstructed. So, how do you determine which type you are? And how should you address it?
First, let's discuss the "yang qi deficiency" type of cold hands and feet. These individuals often not only have cold hands and feet but also experience symptoms such as aversion to cold, soreness and weakness in the lower back and knees, and lack of energy. For example, they catch colds easily in winter, feel comfortable only after drinking hot water, and have clear, profuse urine. From the perspective of etiology and pathogenesis, yang qi deficiency may stem from weak innate constitution or from acquired factors that impair nourishment—chronic illness depleting kidney yang, excessive sexual activity damaging kidney essence, overconsumption of cold and raw foods injuring spleen yang, or advanced age and physical decline. All of these can leave yang qi with no source for generation. The disease primarily involves the spleen and kidneys: the kidney is the foundation of innate constitution and houses the original yang, while the spleen is the foundation of acquired constitution and the source of qi and blood production. The nature of the disease is deficiency and cold; if it persists, it may transition from deficiency to excess, producing a mixed pattern of cold coagulation and blood stasis. In terms of disease progression, without intervention, yang qi gradually depletes, potentially advancing from cold limbs to generalized aversion to cold, mental fatigue, and somnolence.
In specific pattern differentiation, the yang deficiency type of cold hands can be further subdivided into a tendency toward kidney yang deficiency and a tendency toward spleen yang deficiency. Those with kidney yang deficiency often also have cold pain in the lower back and knees, frequent nocturia, especially cold lower limbs, a tongue that is pale and swollen with teeth marks on the edges and a white, slippery coating, and a deep, slow, forceless pulse. Those with spleen yang deficiency often have poor appetite, cold pain in the epigastrium and abdomen, and loose stools, with a tongue that is pale and tender with a white, greasy coating, and a deep, thin, weak pulse. If yang deficiency persists over time and cold coagulates causing blood stasis, one may see purple-dark discoloration of the skin on the hands and feet that turns red slowly after warming, and tortuous sublingual veins. Daily care for such individuals should follow the principle of "nourishing yang in spring and summer." Get more sunlight, preferably on the back, because the Governing Vessel (Du Mai) governs all the yang of the body, and sun exposure helps activate yang qi within. Exercise moderately—such as walking, practicing tai chi, or baduanjin (Eight-Section Brocade)—to the point of slight perspiration, not profuse sweating, lest qi escapes with sweat and further damages yang qi. However, note that this cannot replace professional treatment. If symptoms persist, consult a licensed TCM practitioner, who will recommend moxibustion based on individual constitution. This belongs to the category of external TCM therapies for warming yang, dispersing cold, and invigorating healthy qi, and should be performed under pattern-differentiation guidance.
Second, another common type is cold hands and feet caused by "qi and blood deficiency." TCM holds that qi is the commander of blood, and blood is the mother of qi. Qi can generate blood, move blood, and hold blood; blood can carry qi and nourish qi. If the spleen and stomach's transportation and transformation are impaired, if there is insufficient production of food essence, or if there is chronic illness with inadequate nourishment or chronic blood loss, both qi and blood may become deficient. When qi is insufficient, it lacks the power to push blood; when blood is insufficient, the vessels are empty—so blood cannot be adequately delivered to the peripheral extremities, and the hands and feet naturally become cold. The disease centers on the spleen and stomach, involving the heart and liver; its nature is deficiency, primarily dual deficiency of qi and blood, with complex changes such as blood deficiency generating dryness or qi deficiency generating cold. In terms of progression, if not corrected over the long term, prolonged blood deficiency can lead to depletion of yin blood, producing symptoms such as insomnia, poor memory, and numbness of the limbs due to blood failing to nourish the meridians. In addition to cold hands and feet, these individuals may also have a pale complexion, dizziness, blurred vision, easy fatigue, pale lips and nails, palpitations, insomnia, and scanty, pale menstrual flow in women.
In pattern differentiation, the qi and blood deficiency type requires further identification of whether qi deficiency or blood deficiency predominates. When qi deficiency predominates, fatigue, weakness, shortness of breath, reluctance to speak, and spontaneous sweating are prominent, with a pale tongue, white coating, and a weak, soft, forceless pulse. When blood deficiency predominates, sallow complexion, dizziness, blurred vision, and dry, withered nails are characteristic, with a pale tongue, thin white coating, and a thin, weak or thin, choppy pulse. If both qi and blood are deficient with concurrent cold coagulation, then along with cold extremities, there may be cold pain in the lower abdomen that relieves with warmth, a pale purple tongue, thin white coating, and a deep, thin pulse—this is a mixed deficiency-excess pattern requiring both warming and unblocking in treatment. In terms of diet, one may appropriately consume more red dates, longan, Chinese yam, and similar foods to help supplement qi and blood, along with moderate amounts of warming foods such as beef and chicken to support the source of qi and blood production. However, these methods can only serve as adjuncts; true treatment requires pattern-based diagnosis and therapy. Licensed TCM practitioners often remind that those with qi and blood deficiency should not blindly take tonics—it is necessary to assess via tongue coating and pulse whether there is dampness stagnation, food accumulation, or a situation where deficiency does not tolerate supplementation, before formulating a suitable treatment plan. If there is concurrent phlegm-dampness or qi stagnation,simple supplementation may instead congest qi movement and worsen malnutrition of the limbs.
So, are cold hands and feet only related to constitution? Could they be a signal of other diseases? For example, hypothyroidism, anemia, and diabetes may also cause cold hands and feet. From a TCM perspective, each of these diseases has its core pathogenesis: hypothyroidism mostly belongs to spleen-kidney yang deficiency with internal phlegm-dampness; anemia mostly falls under qi and blood deficiency with insufficient marrow-sea; and chronic diabetes commonly presents with dual deficiency of qi and yin with blood vessel stasis. Therefore, if cold hands and feet are accompanied by severe aversion to cold, abnormal weight changes, dry skin, and other symptoms, it is advisable to first undergo examinations at a regular hospital to rule out organic problems. After excluding disease factors, then consider TCM treatment. It must be clearly understood that TCM treatment targets the improvement of constitutional imbalances and functional disorders, and does not replace modern medicine's diagnosis and treatment of organic diseases—the two can proceed in parallel under the guidance of professional physicians.
For daily care, are there simple and easy methods? From multiple dimensions of lifestyle adjustment, consider the following aspects—
Dietary recommendations and restrictions: Those with yang deficiency should eat warming foods such as lamb, chives, walnuts, and ginger, and may add warming seasonings like scallions, garlic, and pepper during cooking. Those with qi and blood deficiency may eat red dates, longan, Chinese yam, lotus seeds, and animal liver. Both groups should avoid cold and raw fruits, iced beverages, and cold-natured seafood that damage spleen yang. Dinner should not be overly filling to avoid burdening the stomach and stagnating the spleen.
Sleep-wake rhythm: Nighttime is when yang qi hides and yin qi dominates. Staying up late long-term depletes yang qi. It is best to fall asleep before 11 PM and rise in the morning according to natural timing so that yang qi can rise and grow. In winter, one may appropriately sleep earlier and rise later, waiting until sunlight is sufficient before getting up and moving about, to facilitate the storage of yang qi.
Emotional regulation: Extreme emotions can damage all five viscera—excessive fear damages the kidneys, excessive worry damages the spleen, and liver qi stagnation impedes qi movement and constrains yang qi, which can also cause cold extremities. In daily life, maintain a calm mind, avoid excessive tension and anxiety, and relieve emotions by listening to soothing music, practicing calligraphy, or talking with family and friends. When liver qi flows freely, qi moves and blood moves, helping yang qi distribute to the limbs.
Exercise and daoyin (guided exercises): In baduanjin, the movements "Supporting Heaven with Both Hands to Regulate the Triple Burner" and "Climbing the Feet with Both Hands to Strengthen the Kidneys and Waist" help unblock triple burner qi movement and strengthen the lumbar region and kidneys. In wuqinxi (Five Animal Frolics), the "Bear Frolic" and "Deer Frolic" can strengthen the spleen and warm yang. Tai chi, which uses intention to lead qi and qi to move the body, promotes the circulation of qi and blood. Additionally, each morning upon rising or before bed, rapidly rub the palms of both hands together until warm, then place the palms over the soles of both feet. Repeat several times—this also helps guide fire back to its source and warm the lower burner. These daoyin methods should be done to the point of mild warmth, and their benefit lies in persistent, cumulative practice.
Additionally, soaking the feet in warm water before bed, with the addition of ginger slices or mugwort, can help promote blood circulation. However, note that the water temperature should not be too high—38–42°C, comfortable to the body, is appropriate. Soaking time should be controlled to 15–20 minutes, stopping at slight perspiration; excessive sweating can easily damage heart qi. After soaking, dry the feet promptly and put on warm socks to prevent the feet from getting cold again. Regularly rubbing the palms and soles, or doing stretching exercises for the fingers and toes, can also help qi and blood movement. Although these methods are simple, their value lies in persistence, and they can help improve cold hands and feet to some degree. It should be specially noted that the above care methods all belong to the category of daily health maintenance and cannot replace the pattern-based diagnosis and treatment of a licensed TCM practitioner.
Finally, returning to the original question: cold hands and feet that never warm up through the seasons—what exactly should be done? In fact, each person's situation is different, and the key lies in finding the root cause. Is it yang qi deficiency? Or qi and blood deficiency? Or other factors? The disease location may be in the spleen and kidneys, or in the liver and stomach; the disease nature may be deficiency, excess, or a mixture of both—it cannot be generalized. Only through the pattern differentiation of a professional TCM practitioner, comprehensively analyzing the four diagnostic methods and investigating the cause through pattern identification, can a suitable treatment plan be formulated. Although cold hands and feet are a common symptom, they often reflect deeper imbalances of yin and yang and the rise and decline of qi and blood in the body, and deserve attention and long-term management.
