Mormons cannot drink "hot drinks" because of a health code called the Word of Wisdom, a revelation received by their prophet Joseph Smith in 1833, which advises against substances harmful to the body. The phrase "hot drinks" has been interpreted by Church leaders specifically to mean coffee and tea. This prohibition is not necessarily about the temperature of the drinks but about avoiding coffee and teas containing caffeine and substances believed to be harmful or habit-forming. While herbal teas and hot chocolate are generally allowed, coffee and caffeinated tea are strictly prohibited. Following this guidance is tied to the faith's emphasis on physical and spiritual health, and adherence affects church privileges like temple worship. This prohibition originated from a combination of health concerns and religious obedience to God's commandment as recorded in the Doctrine and Covenants section 89.
