Very Hot Beverage Drinking

The chronic pattern of drinking tea, water, and soup at temperatures above 65°C — the WHO IARC threshold above which hot beverages are classified as a Group 2A carcinogen for esophageal cancer.

Why this habit matters

  • Cognition: Reinforces a cultural script that conflates "very hot" with "healthier" or "more potent", which spills into related dietary beliefs and reduces openness to evidence-based modification of the practice.
  • Health: Chronic thermal injury to the oral and esophageal mucosa produces low-grade inflammation, accelerated cell turnover, and increased rates of dysplasia — precursor lesions detected on endoscopic surveillance in heavy-tea regions.
  • Health: WHO IARC Group 2A carcinogen for esophageal cancer above 65°C; Chinese cohort data (Linxian and others) show dose-dependent risk elevation with frequency × temperature × duration of exposure across decades.
