    Next time you make yourself a hot cup of tea or coffee, you might want to let it cool down a bit before drinking.

Researchers say letting your hot drinks cool off could help you avoid some kinds of cancer. Researchers at the International Agency for Research on Cancer (IARC) found evidence that drinks at temperatures above 65℃, when swallowed, can cause cancer of the esophagus（食道）. The researchers examined findings from other studies where tea and coffee were often served at 70℃ or above. Those studies were completed in Iran, China and South America.

In developed countries, health experts have linked esophageal cancer to smoking and alcoholic drinks. However, this form of cancer is more common in areas where people drink beverages（饮料）at very high temperatures.

In Europe and the United States, many people drink coffee and tea at temperatures around 60℃.And they often add milk which lowers the temperature greatly. However, tea-drinkers in Iran and mate-drinkers in South America often enjoy their beverages at closer to 70℃.

The researchers find that South Americans not only drink their mate very hot, they also drink it through a metal straw. This sends the scalding liquid directly into the throat.

The findings, however, are good news for coffee drinkers. In 1991, the World Health Organization (WHO) listed coffee as possibly carcinogenic（致癌的）. The WHO officials have since changed their position on that listing. They now suggest that the temperature of your hot drink is a greater risk factor than the actual drink.

The results suggest that drinking very hot beverages is one probable cause of esophageal cancer and that it is the temperature, rather than the drinks themselves, that appears to be responsible.
