Banerjee said she had asked the state's education minister, Bratya Basu, to extend the summer vacation in schools till June 18 to insulate children from the intense heat.
"Movement of children should be restricted during this condition, Oral Rehydrated Solution (ORS) should be taken frequently and even the elders should also minimise their movement outside as a precautionary measure," the chief minister advised.
Following acute scarcity of drinking water in several districts, Banerjee said that she had also asked the state's Panchayat, Rural Development and PHE Minister Subrata Mukherjee to arrange for drinking water in those areas where ground water level has drastically gone down.
"Heat wave is no longer confined to the districts like Bankura and Purulia. The entire state is affected," she said.
