In what universe does swimming in room-temperature water make someone sick?
Did you even read my explanation? Two pools, one heated and one that wasn’t. Why were they the same temperature? If one was heated to 25c then it should have been warmer? I used to have a pool which took ages to heat and felt exactly like the so called heated pool when it wasn’t heated. So the temp must have been around 18-20c.
