Frequent cold, cough, and throat congestion during summer can be a sign of 'Cold Shock'. Entering an AC room directly from scorching heat weakens the immune system. Dry AC air depletes moisture in the respiratory tract, leading to a dry throat and blocked nose. Consuming extremely cold items like ice cream and chilled water affects the mucus membrane, increasing infection risks. Dust allergies also contribute to cold symptoms. To stay safe, maintain AC temperatures between 24-26°C, avoid drinking cold water immediately after returning from outside, and stay hydrated. https://samacharpradesh.com/news.php?id=why-are-sudden-changes-in-temperature-in-summer-harmful-learn-the-full-details-623323 #creator program
