* Lack of physical activity. Many school children spend a lot of time sitting in class, which can lead to a lack of physical activity. This can contribute to obesity and other health problems.
* Stress. School can be a stressful environment, which can lead to a decrease in the immune system. This can make children more susceptible to disease.
* Poor nutrition. Children who do not eat a healthy diet are more likely to get sick. This is because a healthy diet provides the body with the nutrients it needs to function properly and fight off infection.
* Exposure to germs. School children are exposed to a lot of germs, which can increase their risk of getting sick. This is especially true in schools that are overcrowded or have poor hygiene.
It is important to note that not all school going children are lazy and disease prone. There are many school children who are active, healthy, and well-nourished. However, the factors listed above can contribute to the perception that school going children are lazy and disease prone.
