Steaming-hot Tea Linked to Throat Cancer

According to an Iranian study, drinking scalding hot tea that is greater than 158°F (70°C) has been shown to increase the risk of throat cancer. Participants in the study who made black tea and drank it two minutes after pouring were five times as likely to develop throat cancer as compared to those who let their tea sit for four or more minutes. Researchers think the relationship between super-hot tea and cancer is connected to repeated injury to the lining of the throat.

Cancer of the esophagus is one of the deadliest cancers out there, and 500,000 people worldwide die each year from it. So make sure to take preventative measures by allowing your hot tea to cool so that it's warm or lukewarm, and less than 149°F (65°C).
