i drink water that comes in bottle. either Poland springs or the Costco ones. I been doing this all my life and i don't think there's anything wrong. Also the bottle water is more cold then warm because we leave it under the table
Always have perfered to drink cold than hot for something reason hot water intend to dry my throat and make me thristy more
Neither , I drink lukewarm , Boiled water mixed with filtered cold water. I onyl drink cold water after sport or on hot days.
it depends on season, summer time of course cold water will be better, other times room temperature water is better I think.hahahh
