Sipping tea at dangerously high temperatures, especially above 65°C, has been associated with a higher risk of oesophageal cancer. Research suggests the heat can damage the oesophagus lining, triggering chronic inflammation and increasing the chance of cellular changes. Doctors advise letting tea cool for a few minutes to cut the risk while keeping your habit intact.

Researchers say it is associated with higher levels of oral bacteria linked to periodontal disease and cancers of the esophagus and colon. The authors urge consistent oral hygiene practices to lower risk and keep mouths healthy.
