New Research Confirms Risks of Drinking Very Hot Beverages

Following our recent reports on the potential health risks of hot beverages, new data has provided a clearer picture of how our daily habits affect our long-term health. A massive study, published recently in the International Journal of Cancer, has confirmed that drinking tea and coffee at very high temperatures can triple the risk of developing a specific type of throat cancer. This research, led by Dr. Keren Papier at the University of Oxford, is the largest of its kind, tracking the habits and health of almost 980,000 people in the UK over a period of 14 years.

The study focuses on oesophageal squamous cell carcinoma (SCC), a form of cancer that affects the foodpipe. According to The Guardian Health, the findings show a clear link between the temperature of drinks and the risk of this disease. While the study did not find that hot drinks increase the risk of all types of throat cancer, the connection to SCC is significant. Researchers noted that the risk increases not only with the temperature of the drink but also with how often a person consumes them. Specifically, people who drank six or more hot drinks every day faced a 71% higher risk of this cancer compared to those who drank fewer.

This new information builds upon previous concerns raised by the World Health Organization. In 2016, the International Agency for Research on Cancer identified hot drinks as a probable cause of cancer. The current theory is that very hot liquids cause physical damage to the cells that line the foodpipe. Over time, this repeated heat damage may lead to the development of cancer. These latest findings from the UK mirror similar trends previously observed in studies across Asia, Africa, South America, and the Middle East, where drinking very hot tea or herbal drinks like mate has long been a subject of health concern.

One of the most important aspects of this study is that it relies on how people describe their own drinking habits. Participants were asked to categorize their preferred drink temperature as “very hot,” “hot,” or “warm.” The researchers found that even without measuring the exact temperature of every cup, the trend was clear: those who preferred “very hot” drinks were at a much higher risk. The study team suggests that this is a preventable health issue. They estimate that one in seven cases of this specific cancer in the UK could be avoided if people simply chose to drink their tea or coffee at a “hot” or “warm” temperature instead of “very hot.”

It is important to note that while this study highlights the risks of heat, other factors like smoking and alcohol consumption remain major causes of throat cancer. However, the researchers believe that health authorities can use these new findings to encourage simple, effective lifestyle changes. By waiting just a few minutes for a drink to cool down, individuals can significantly lower their risk without giving up their favorite beverages entirely. The study suggests that the goal should be to consume drinks at a temperature well below the “very hot” category.

As we continue to look at how daily habits influence our health, this study serves as a helpful reminder that small changes can have a big impact. While the findings are specific to a Western European population, the consistency with global data suggests that the advice to let drinks cool down is universal. Moving forward, health experts hope that public awareness will lead to a decrease in the number of people diagnosed with this form of cancer. For now, the best advice remains simple: enjoy your tea or coffee, but give it a little time to reach a safer, more comfortable temperature before you take that first sip.
