Preventing Colds During Seasonal Transitions
Colds frequently occur during seasonal transitions, particularly between autumn-winter and winter-spring. Although cold exposure is commonly believed to be the cause, it is merely a trigger. The true cause lies in viral and bacterial infection. Normally, viruses and bacteria reside in the human respiratory tract, coexisting peacefully due to the body’s resistance and protective mucosal barrier. However, when children become chilled, overeat, overwork, or experience fright, their immunity drops, allowing these pathogens to invade and cause illness. Additionally, after seasonal cooling, windows are rarely opened, indoor air becomes polluted, increasing bacterial and viral density. Simultaneously, increased indoor activity raises infection risk. Prevention hinges on strengthening the body’s and respiratory tract’s adaptability to cold air and preventing pathogen invasion. Even in cold seasons, outdoor activities should be maintained; avoid overdressing children, and avoid excessively high room temperatures. Focus on building children’s cold tolerance. Regularly open windows for ventilation—a simple, economical, and effective method for cleaning indoor air. Also ensure children’s daily activities have rhythm, avoiding overeating. Finally, parents should note: over 90% of childhood colds are caused by viruses, rendering antibiotics ineffective. Avoid indiscriminate antibiotic use in children, as misuse may lead to secondary infections. Herbal decoctions are highly effective; for high fever, antipyretics may be used, along with increased water intake to aid fever reduction. Children under 5 years old should not use APC for fever reduction, as it contains caffeine, which may cause overexcitement or convulsions. If bacterial infection causes the cold, antibiotics should be used—but only one type is necessary.<Cold>
