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 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 considerably. However, tea-drinkers in Iran and mate-drinkers in South America often enjoy their beverages at closer to 70℃.
The researchers note 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 listed coffee as possibly carcinogenic (致癌的).” 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 itself.
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.

In high school I was very shy, content to hang around with my small group of friends and to concentrate on my courses. I was quickly labeled a "brain." I did so well that by the end of senior year I had perfect grades and enough college credits to give up an entire quarter of coursework.
But in early June of senior year, the principal called me into his office. He asked me to give a speech at graduation. I was surprised to look at him, my heart thumping. This was the reward for my hard work? I murmured something and fled the office, blaming myself for staying away from physics, a subject sure to have broken up my perfect record.
I finally agreed to a compromise. I would share the honor with five other students. I agreed to introduce my friend Judy, who would then give her own, full-length speech.
Graduation day soon arrived, I’d been practicing my speech for days, and I had it memorized. The first half hour of the ceremony passed in a blur, and then my moment came. My name was announced. I managed to reach the stage without falling down. I faced my classmates. My voice trembled a little, but mostly it was clear and strong. But within seconds, I was done and heading back to my seat. I accomplished something I’d never dreamed of — I spoke in front of hundreds of people.
Although I didn’t realize it at the time, the successful completion of that speech gave me the confidence to take part in class at college, to give oral reports, and to eventually break free of my shyness. I never would have chosen to give a speech at graduation — or ever. But I’m glad I did. I no longer hesitate when I’m faced with the prospect of doing something I feared. I know it may very well turn out to be one of my shining moments.
