Drinking very hot beverages above 65°C has been classified as probably carcinogenic to humans by the International Agency for Research on Cancer since 2016. Research primarily from South America, the Middle East, Africa, and Asia linked consumption of very hot drinks like maté to higher risks of oesophageal cancer. A 2025 UK study involving nearly half a million adults confirmed that drinking eight or more cups daily of very hot tea or coffee increases the risk of oesophageal cancer nearly sixfold compared to non-drinkers. The risk is associated with the temperature and volume consumed, as large sips of hot drinks raise oesophageal temperature significantly, potentially damaging the lining and promoting cancer development. Animal studies support these findings, showing accelerated precancerous growths with very hot water exposure. The damage may also weaken the oesophageal barrier, increasing vulnerability to acid reflux. Experts recommend allowing hot drinks to cool to around 58°C and taking small sips to reduce risk. This evidence highlights the importance of temperature management in hot beverage consumption to mitigate oesophageal cancer risk. (Updated 22 Aug 2025, 00:12 IST; source: link)
