Everybody's bodies are different...some like it hot...some like it cold. It's no different with the water we drink. If you're struggling to drink your water quotient for the day maybe it's because of the temperature! I love hot foods and hot drinks...the thought of drinking cold water freaks me out...so I drink hot water (with a wedge of lemon, if possible) or room temperature water when I'm not near a kettle! It goes down so much easier than cold water!!
