To this end, many parents spare no effort in supplementing their babies with various nutrients and nutritional powders, hoping to boost their immunity. However, relying solely on external supplements yields limited results, and many children still end up at the hospital with colds and fevers.So how can we properly boost a child's immunity?
Resistance refers to the coordinated effort of all bodily systems, controlled by the central nervous system, to ensure normal physiological functions. The immune system plays a crucial role in this process. Its primary function is to defend against invading pathogens that cause disease. This inherent defensive capability is what we call resistance.
Signs of low immunity in infants:
Immunity primarily originates from two sources. The first is acquired after illness, when the body produces specific antibodies against the pathogen. Upon re-exposure, these antibodies team up with white blood cells to eliminate the pathogen, preventing illness. Some such immunity lasts long-term (e.g., measles antibodies), while others are temporary (e.g., cold antibodies).After receiving vaccinations, the body actively generates immunity in response to the stimulus. This type of immunity is generally lifelong.
The second source of immunity is "passive." For example, newborns (infants within one month of birth) acquire immunity by receiving numerous antibodies from the mother. Similarly, injecting immunoglobulin (antibodies against specific diseases) may provide temporary protection against certain rare illnesses.
Consider whether your baby has weakened immunity if they exhibit the following symptoms: irregular bowel movements prone to diarrhea; frequent illness during seasonal changes; slow wound healing with susceptibility to infection; frequent infections from peers in group settings; persistent colds occurring more than three times a year.
So how can you boost your baby's immunity?
Provide adequate nutrition
Babies are in a constant state of growth and development, requiring relatively high levels of nutrients. However, due to their immature digestive systems and often limited diets, they are prone to nutrient deficiencies. Insufficient nutrition weakens resistance. Current research indicates that mild (or subclinical) deficiencies in vitamins A and C are common causes of recurrent respiratory infections in children.Therefore, consuming fresh, colorful fruits and vegetables rich in vitamin C (whose beta-carotene can be converted into vitamin A in the body) or supplementing with multivitamins can effectively boost a baby's resistance.
Engage in Physical Exercise
This is crucial for strengthening overall physical condition. Exercise should begin early. After one month of age, babies can lie outdoors briefly in summer or breathe fresh air indoors with windows open in winter, without overdressing.Gradually acclimating infants to cooler environments helps prevent colds during seasonal changes. Outdoor activities not only enable skin synthesis of vitamin D—promoting calcium absorption—but also benefit muscle, bone, respiratory, and circulatory system development, while boosting overall metabolism. Regular exercise also stimulates appetite. Ensuring adequate nutrient intake strengthens the body and significantly enhances immunity.
Drink plenty of plain water—keep mucous membranes moist
Adequate hydration maintains mucous membrane moisture, forming a crucial defense against bacteria. Have children carry water bottles to kindergarten or outings for immediate hydration when thirsty. Note: Opt for plain water over sugary beverages.
Avoid excessive cleanliness—build immune memory
The immune system develops memory against pathogens, enabling swift elimination upon re-exposure.
An overly sterile home deprives children of opportunities to develop antibodies through exposure, potentially weakening immunity and increasing allergy or autoimmune disorder risks.
Regular soap and water suffice for daily hygiene; avoid daily disinfectant use.
