Why is hot water used normally to brew tea?

Hot water is used to brew tea because it helps extract the flavors, aromas, and beneficial compounds from the tea leaves more effectively than cold water. The heat facilitates the release of essential oils and soluble substances, enhancing the overall taste and color of the tea. Different types of tea may require specific water temperatures to achieve the best flavor profile, as too hot water can scorch delicate leaves, while cooler water may not extract enough flavor.
