Many people enjoy their drinks piping hot, but new research shows temperature matters. Beverages hotter than 65°C are linked to a higher risk of esophageal cancer. The danger isn’t from coffee or tea itself, but from the heat, which can damage the lining of the esophagus over time.

Studies suggest people who regularly drink extremely hot beverages may be several times more likely to develop cancer, especially if they sip quickly or consume large amounts. Repeated heat damage makes the esophagus more vulnerable to harmful changes.

Experts recommend letting drinks cool slightly before sipping and avoiding large gulps of steaming liquid. Waiting just five minutes can lower the temperature by 10–15°C. The safest choice is to enjoy coffee or tea at around 57°C—still warm and flavorful, but not hot enough to cause harm.
