When the weather turns cold, many parents find that children are more susceptible to illness with symptoms such as runny nose, prolonged cough or mild fever. According to experts, this is a common phenomenon and has a clear scientific cause related to seasonal immune deficiency.
Dr. Vrajendu BB, a pediatrician at Fortis Nagarbhavi Hospital (Bengaluru, India) said that winter creates many disadvantages that make children's immune systems less effective, thereby increasing the risk of disease.
Why does the child's immune system decline in winter?
Cold and dry air is one of the main causes. These weather conditions dry the mucous membranes of the nose and throat, which are the body's first protective barrier against bacteria and viruses. When this protective layer weakens, pathogens penetrate more easily.
In addition, in winter, children tend to stay indoors more often, in closed and less ventilated spaces. Close contact between children in classrooms, playgrounds or kindergartens creates favorable conditions for the virus to spread quickly.
Another important factor is vitamin D deficiency. Reduced sun exposure reduces the amount of vitamin D in children's bodies, while this is a micronutrient that plays an essential role in the activities of the immune system.
In addition, sudden temperature changes when moving between warm indoor and cold outdoor environments also put pressure on the body, reducing the temporary adaptability of the immune system.
Common health problems in children in winter
According to Dr. Vrajendu BB, winter is a time when children are prone to problems such as recurrent colds and coughs, sore throats, respiratory infections, flu-like symptoms, asthma worsening, increased allergies, prolonged fatigue and longer recovery time.
Although these are common conditions, parents can still significantly reduce the risk if they focus on proper care.
How to strengthen the immune system for children in winter
Dr. Vrajendu BB emphasized that daily living habits play a key role in improving children's resistance.
First of all, it is necessary to build a balanced, nutritious diet with many vegetables, fresh fruits, whole grains and seasonal foods. Foods rich in vitamin C, zinc and antioxidants help children's bodies fight infection better.
Parents should also encourage children to play outdoors reasonably. Just about 20 to 30 minutes of sun exposure a day can help maintain vitamin D, while improving mood and fitness.
Keeping children hydrated is something that should not be ignored, even if children rarely feel thirsty in cold weather. Warm water, soup, coconut water or fresh fruit juice are suitable choices.
A full and quality sleep helps the body recover and strengthen the immune system, especially important for young children. At the same time, forming good hygiene habits such as washing hands regularly, keeping the body warm and limiting cold drinks also helps reduce the risk of disease.
