Drinking Hot Tea Linked to Higher Cancer Risk, Experts Caution

According to a recent report, health experts are urging tea drinkers to be cautious about the temperature of their beverages. They warn that regularly consuming tea hotter than 65°C can significantly increase the risk of esophageal cancer.

A 2020 Chinese study found a strong link between drinking very hot tea (above 65°C) and a specific type of esophageal cancer called esophageal squamous cell carcinoma. Experts advise tea drinkers to wait for their tea to cool down before sipping.

In addition to temperature concerns, the report also highlights issues with caffeine and sugar content in certain tea varieties. Experts caution against drinking caffeinated teas like chai and green tea late at night, as the caffeine can disrupt sleep and prevent the body from properly repairing itself.
