Many students carry large water bottles to school because drinking water may not always be available nearby throughout the day. These bottles significantly increase the weight of school bags along with books and notebooks.
Students travel long distances by walking, buses, or autos while carrying this heavy load daily. Continuous carrying of excess weight may cause shoulder pain, back discomfort, fatigue, and posture problems. Some students even avoid drinking enough water to reduce bag weight, which may lead to dehydration during summers.
This issue is very common in schools with large student populations or limited drinking water access on every floor. The problem affects students regularly and over long periods.
