Recurrent Common Cold in Children
Overview
Recurrent common cold in children refers to frequent episodes of cold symptoms occurring repeatedly within a year, often protracted and difficult to resolve, most commonly seen in children aged 6 months to 6 years. In TCM, this condition falls under the categories of "cold in the deficient person" or "constitutional weakness with recurrent cold." The key pathogenesis lies in insufficient healthy qi (zheng qi), insecurity of the defensive exterior, and repeated invasion of external pathogens. Children have delicate zang-fu organs and insufficient form and qi; the lung, spleen, and kidney are often deficient. If there is congenital insufficiency or improper postnatal care, lung qi becomes weak, the defensive exterior is insecure, and interstices are loose, allowing external pathogens to invade. Alternatively, spleen deficiency leads to impaired transformation and transportation, insufficient production of qi and blood, and earth failing to generate metal, resulting in lung qi deficiency. Or kidney qi insufficiency and depletion of original yang fail to warm the defensive yang. In addition, improper feeding, internal heat from food stagnation, and inadequate care are common triggers. Clinically, recurrent nasal congestion, rhinorrhea, sneezing, cough, and fever are the main manifestations, often accompanied by pale complexion, spontaneous sweating, night sweats, poor appetite, and fatigue. Treatment should focus on supporting the upright and consolidating the root, while addressing pathogens; during remission, tonify the lung, spleen, and kidney; during acute episodes, treat both the root and the branch.
Pattern differentiation (clinical patterns)
Lung and Spleen Qi Deficiency
Recurrent colds, pale complexion, shortness of breath and laziness to speak, spontaneous sweating and night sweats, poor appetite and loose stools, pale tongue with thin white coating, and a weak fine pulse.
Tonify the lung and spleen, augment qi and consolidate the exterior.
Disharmony between Ying and Wei
Recurrent colds, aversion to wind with spontaneous sweating, sweating without relief, mild body heat, nasal congestion and rhinorrhea, pale red tongue with thin white coating, and a floating moderate pulse.
Harmonize ying and wei, release the muscle and promote sweating.
Spleen and Kidney Yang Deficiency
Recurrent colds, aversion to cold and cold limbs, pale and puffy complexion, mental fatigue and weakness, poor appetite and loose stools, clear and long urine, pale swollen tongue with white slippery coating, and a deep fine pulse.
Warm and tonify the spleen and kidney, assist yang and consolidate the exterior.

Daily care & prevention
Avoid wind-cold, adjust clothing appropriately, and prevent sweating while exposed to wind. Diet should be light, easy to digest, and nutritionally balanced; avoid raw, cold, greasy, sweet foods, and snacks, and correct picky eating. Ensure adequate sleep, appropriate outdoor activities, and sun exposure to strengthen the constitution. During cold epidemics, avoid crowded places, wear masks, and wash hands frequently. Pediatric tuina health care can be performed, such as pinching the spine, rubbing the abdomen, and pressing Zusanli (ST36). During remission, under medical guidance, take supportive formulas such as Yu Ping Feng San. Observe changes in the condition; if episodes are frequent, seek timely medical attention for systematic regulation.
When to seek medical care
If there is persistent high fever, listlessness, lethargy or irritability, rapid breathing, nasal flaring, cyanosis of the lips, severe cough with chest pain, severe vomiting and diarrhea leading to dehydration, convulsions, dense rash or petechiae, pale complexion, or cold limbs, this indicates a critical condition or complications and requires immediate medical attention. Recurrent colds with growth retardation, emaciation, or anemia warrant further investigation for underlying diseases such as immunodeficiency.
