Health experts explain that the esophagus the food pipe is thin, delicate, and far more sensitive than the stomach. Unlike the stomach, it is not built to handle repeated exposure to extreme heat.
Drinking very hot beverages on a daily basis can irritate its inner lining, sometimes without obvious pain.
These small burning moments often go unnoticed. Yet over time, they can pile up. The tissue gets injured, heals, and then gets injured again. This repeated stress may slowly change how cells behave, increasing the risk of esophageal cancer.
Research reviewed by the UK Biobank points to a clear pattern: people who regularly drink tea or coffee at very high temperatures face a higher long-term risk of throat and esophageal cancer. The risk does not come from a hidden chemical or rare ingredient it comes from heat itself.
Studies also show that countries where boiling or steaming-hot drinks are commonly consumed tend to report higher rates of this cancer. Large gulps are especially harmful, as the liquid stays in contact with the throat for longer.
Drinking eight or more extremely hot beverages a day raises the danger further, but even fewer drinks can be risky if they are hot enough.
Thermal mugs and flasks add another concern. They keep drinks hot for hours, meaning a single cup prepared in the morning can still be damaging later in the day.
Experts suggest small, practical changes that can make a real difference. Let hot drinks cool for a few minutes before sipping. Stir the drink or open the lid to release steam. Add milk or a little cool water to lower the temperature. Researchers say beverages are safer to drink at around 58 degrees Celsius.
These habits may seem minor, but for the soft tissues of the throat, they matter greatly. Sometimes, protecting health is not about giving something up it is about slowing down, waiting a moment, and taking a gentler sip.
