A growing body of research suggests a potential link between consuming very hot beverages and an increased risk of esophageal cancer, prompting new guidance from oncologists [[1]]. The World Health Organization classifies drinks above 149°F as “probably carcinogenic,” and studies across multiple continents indicate repeated thermal injury to the esophagus might potentially be a contributing factor [[2]]. This report details the emerging understanding of this risk and recommendations for mitigating it, as esophageal cancer remains a notable public health concern, ranking among the deadliest digestive cancers [[3]].
Drinking very hot beverages may increase the risk of esophageal cancer, according to oncologists. The concern stems from repeated exposure to scalding liquids, which can damage the lining of the esophagus over time.
Experts recommend allowing hot drinks to cool to a comfortable temperature before consuming them. The World Health Organization considers 140°F to 149°F (60°C to 65°C) a safe limit for drinking hot beverages, but waiting a few minutes after preparation is even more important. “It’s more important to avoid drinking liquids immediately after they’re made, when they’re still scalding,” suggests a specialist in head and neck tumors. “Ideally, wait until the beverage is lukewarm and comfortable to drink.”
Brazil, a major coffee-consuming nation, has seen research linking very hot beverages – particularly *chimarrão*, a traditional South American drink – to an increased risk of esophageal cancer. This finding highlights the importance of being mindful of beverage temperature regardless of cultural practices.
Similar Risks Across Cultures
Studies conducted in southern Brazil have shown a consistent association between very hot drinks and squamous cell carcinoma, a type of esophageal cancer. “This risk appears to be consistent across different countries and cultures,” the oncologist observed. This suggests a universal biological mechanism at play, regardless of specific beverage type or regional habits.
Esophageal cancer is the sixth most common cancer among men and the 15th most common among women, according to the National Cancer Institute. It ranks among the leading causes of cancer-related deaths from digestive tract cancers in the country. Symptoms often appear in advanced stages, making early diagnosis challenging, which underscores the importance of preventative measures.
Other lifestyle factors and health conditions can also contribute to the risk of developing esophageal cancer. These include smoking, excessive alcohol consumption, obesity, gastroesophageal reflux, and a diet low in fruits and vegetables. According to experts, these factors can have a cumulative effect, increasing overall risk.
