Is it ok to water your container plant with warm water during the cold?

I am not using hot water. Just mildly warm to get the chill out. I have a Tomato plant I am experimenting with and have been taking it in the garage during freezes and am wondering if using warm water is ok or will it kill it?

We live in North Florida so the weather is cold during the evenings but warms up to the 60’s during the day.
Thanks!

Temperature changes cause a shock to the plant. Ideally, the water you use should be the same temperature as the soil around the plant.

This is most easily achieved by leaving your full watering can out next to the plant for a couple of hours before watering.

I’ve always been told to use cold water left out to get to room temperature to water plants. I don’t think warm water is a good idea.
