Which one is better for people , hot water, warm water, cold water I know many western people like drinking cold water, especially in the U.S. No matter what the weather is like , American resturants provide cold water to customers. And you can always see people drinking cold water in American movies or TV plays. But In China, many people like drinking hot water, especially the elderly and the women. They concider drinking hot water can warm intestines and stomach and can prevent the infections. So hot water is good for health. This is also one of the Chinese traditional customs. However I once read an article , it says drinking too hot water can increase the risk of getting esophagus cancer. So I think drinking warm water , room temperature water, lukewarm water are beeter for most people. Maybe cold water is just for after workout, hot weather, calming the pain down ,or few people.
