What Are Seasonal Diseases?
Seasonal diseases are illnesses that occur more frequently during specific times of the year, often because of changes in weather and temperature. In the winter season, these diseases become more prevalent due to cold weather, weakened immunity, and the tendency for people to spend more time indoors. This environment can lead to the rapid spread of viruses, bacteria, and allergens.
Cold temperatures can weaken the immune system, making the body more susceptible to infections. The low humidity in winter air also dries out mucous membranes, reducing their ability to filter germs. Additionally, viruses such as the common cold and flu thrive in cooler conditions, making them more likely to infect people during the winter months.
