Delhi heatwave advisory: School bells to alert students to drink water every hour

Amid rising temperatures, schools in Delhi have been directed to ring a bell every 45-60 minutes to remind students to drink water and pair them up in a \"buddy system\" to monitor each other's health. These are part of fresh precautionary measures issued by the Directorate of Education (DoE) on Tuesday for Delhi government schools, aided schools and private unaided recognised schools. This comes as the India Meteorological Department (IMD) warned of likely heatwave and adverse weather conditions in the national capital in the coming days. Under the \"water bell\" system, schools have been asked to ring a bell every 45 to 60 minutes to remind students to drink water and prevent dehydration, the DoE circular said. It said outdoor assemblies should either be curtailed or shifted to shaded or indoor areas with minimum duration, while no open-air classes should be conducted.
