What environmental factor can exacerbate respiratory infections?

Humid conditions can exacerbate respiratory infections for several reasons. Higher humidity levels can increase the growth of mold, dust mites, and other allergens that can irritate the airways. When humidity is elevated, it can also lead to an increase in the proliferation of certain viruses and bacteria that thrive in moist environments.

Additionally, high humidity often correlates with poor indoor air quality, particularly if ventilation is inadequate. This poor air quality can further compromise respiratory health, making individuals more susceptible to infections. In environments with excessive humidity, individuals may experience more pronounced respiratory symptoms and have a harder time managing existing conditions, leading to increased cases of infections.
