Bub perspires a lot, even when aircon is on, but say at 24-25 degrees. How can I better train her not to perspire so much?

My baby sweat a lot too. Prolly cos he is v active but at times Even when he is in aircon room and he jumps and roll about he will still sweat. And yes I set aircon at 25 and hv a small fan blowing at us, this helps to keep my son and me cooler and dryer. Quite impossible to train someone not to sweat though cause even me myself and hubby sweats no matter how. lol! Oh ya one thing is give ur baby some water to drink if he/she perspire a lot ya. Keep them hydrated too.
