उत्तर
A lot of sweating happens when you play outdoor games. This results in the loss of water, sugar, and salt from the body. This can sap your energy. Glucose solution quickly replenishes lost water and sugar. That is why Nitu’s teacher used to tell the girls to have glucose while they were playing hockey.
