Reasons for summer colds
Russian doctor Svetlana Bornatskaya pointed out that the sudden transition between high temperatures and low humidity during the summer—such as moving from 35°C heat to an air-conditioned room at 18 or 20 degrees—weakens the mucous membrane defenses in the nose and throat, increasing the likelihood of catching colds and viral infections. She also explained that drinking cold beverages, swimming in cold water after exposure to intense heat, and direct exposure to strong air conditioning can cause hypothermia and weaken the immune system, making it easier for viruses to enter. She emphasized that air conditioners are not a source of viruses unless their filters are dirty, as increased air dryness can dry out mucous membranes and raise the risk of respiratory infections.
