Do you warm your babies bottles or use room temp water? why/why not?

I always warmed DD water prior to adding the formula. DD was a winter baby & I thought there would be nothing worse than giving her a cold/luke warm bottle plus like one of the others said, the forumla mixes easier

We always warmed our bottles up, your breast milk is your body temp so its warm anyway.
I we live in a cold place and I didnt like giving my babies cold milk.
I was always told to warm the water then add the powder as you shouldnt warm pre made formula in the microwave. You can warm it in hot water though.
