A new study indicates that consuming hot beverages like tea or coffee may triple the risk of certain cancers. The research, conducted in Golestan Province, Islamic Republic of Iran, focused on a population with traditionally high consumption of extremely hot tea. Researchers observed a significant correlation between drinking temperatures above 65°C (149°F) and an elevated cancer risk, particularly in the esophagus. The study controlled for lifestyle factors such as smoking and alcohol consumption, strengthening the link to beverage temperature. While further research is needed to confirm these findings in other populations, the results highlight a potential public health concern, particularly in regions like the Islamic Republic of Iran and parts of Turkey and the Caucasus, where very hot tea is common. Individuals are advised to allow hot drinks to cool slightly before consumption to potentially mitigate the risk.
