As temperatures drop in northern and central India, a rise in seasonal illnesses like colds, coughs, and flu is being observed across all age groups. Factors contributing to winter illnesses include lower temperatures weakening the immune system, increased indoor circulation of viruses, dry air irritating the respiratory tract, and reduced sunlight leading to lower Vitamin D levels. Maintaining a balanced diet, staying hydrated with water and herbal teas, and other immunity-boosting practices are recommended to prevent and lessen the severity of these common winter ailments.
