There are many reasons to enjoy drinking tea. However, you should let the hot tea cool down a little before you drink it. Why?A new study in the International Journal of Cancer gives the answer.

"Many people enjoy drinking tea, coffee or other hot drinks. However, according to our report, drinking very hot tea can increase the risk (风险) of esophageal cancer (患食道癌), so you'd better wait until hot drinks cool down before drinking," the lead writer of the study, Dr. Farhad Islami of the American Cancer Society, said.

For the study Islami and his team followed more than 50,000 people aged between 40 and 75 years old. They found 317 of those people had esophageal cancer. The National Cancer Institute reported that about 17,290 Americans had esophageal cancer in a year and that only about 19% of sick people survived. However, five years later, they died. 

The scientists found that drinking 700ml drinks (about three cups) every day or more at a higher temperature (温度)(60℃or hotter) would have a 90% higher risk of having esophageal cancer, compared (比较) with people drinking the same quantity at a temperature below 60℃.

This is not the first report showing a person drinking very hot drinks has the risk of cancer. In 2020, the World Health Organization showed a report. It found that drinking very hot drinks of any kind could increase the risk of cancer.
