Ice water is simply water that has been cooled down by adding ice cubes. This process lowers the temperature of the water, making it refreshing and enjoyable, especially on hot days. Ice water is commonly served in restaurants and is a popular choice for hydration. Drinking ice water can help cool the body and may aid in digestion. Some people prefer it over room temperature water for its crisp taste. Additionally, ice can be made from various sources, including tap water or filtered water, ensuring that the quality of the ice matches the desired taste of the drink.
