The phenomenon of experiencing a runny nose primarily indoors during winter can be attributed to a combination of environmental factors and the body’s physiological responses. In cold weather, the body works to warm and humidify the air before it reaches the lungs, which can cause the nasal passages to produce more mucus. This is an automatic response to prevent the cold air from irritating the sensitive tissues of the respiratory tract.
Additionally, indoor environments in winter are often sealed off to conserve heat, which can lead to the accumulation of irritants and allergens that might not be as concentrated in the warmer months when ventilation is more frequent.
