During the first days of school, children often encounter many obstacles due to changes in school, teachers, friends, and eating and sleeping habits that are very different from those at home. One of the problems that most parents worry about is that their children get sick when they first go to school. That means parents should prepare ways to prevent diseases during the back-to-school season for their children.

Everyone knows that during the changing seasons, the weather and humidity change erratically, making it difficult for the body to adapt, creating conditions for viruses and bacteria that cause respiratory diseases to thrive. Respiratory diseases are the most common; such as flu, rhinopharyngitis, pharyngitis, bronchitis, pneumonia and recurrence of chronic diseases such as bronchial asthma, obstructive pulmonary disease or chronic cardiovascular disease.

Medically, coughing is a necessary reflex that protects the body. When something invades the airways, the respiratory system will stimulate the child to cough. During daily life, there are many factors that can enter the airways, causing the child to cough to expel foreign objects.
