As temperatures drop, certain illnesses become more widespread due to weather changes and weakened immunity. The most common winter illnesses include influenza, common cold, sore throat, and sinus infections. These conditions spread easily through the air or by touching contaminated surfaces.
To prevent them, it is recommended to:
-
Wash hands regularly
-
Boost immunity with Vitamin C
-
Wear warm clothing
-
Avoid crowded places when possible
-
Get the annual flu vaccine
Following these steps significantly reduces the risk of infection and helps maintain a healthy respiratory system.
