Lars Arendt-Nielsen, a pain researcher at Aalborg University, has contributed to a study on the phenomenon known as "cat's tongue", a term used to describe sensitivity to hot drinks. Arendt-Nielsen explains that the oral mucous membrane is less protected from heat compared to skin, acting similarly to skin without an epidermis. He notes that while hot liquids can harm mouth tissues, their quick distribution and swallowing prevent extensive burns. However, very hot drinks can cause minor throat burns and potentially increase the risk of esophageal cancer.
