Let hot drinks before consumption cooling

When people are hot regular tea (60 ° C or more) drink, this is associated with an increased probability for the emergence of esophagus cancer by 90 percent. To avoid this risk, we should let the freshly-boiled tea cool for a few minutes before we consume it. Very hot water irritates the lining of the mouth and throat, which can stimulate the emergence of tumors, explain the researchers. Esophageal cancer is the eighth most common cause of Cancer worldwide and one of the main causes of death due to cancer. The tea-based results of the study were also on other hot drinks transferable, including coffee or hot chocolate, explain the authors.

The study had over 50,000 participants

For the study, the drinking habits of 50.045 people between the ages of 40 and 75 years were studied, which is in the North-East of Iran lived. From the year 2004 to the year 2017, 317 new cases of esophageal cancer were identified. The study results indicate that existing instructions apply to a connection between the consumption of hot beverages and esophageal cancer in fact.

Why increase the hot drinks, the risk of cancer?

Different mechanisms could explain how the Drinking of hot drinks is cancer in the esophagus.

Oesophageal cancer mainly affects people between the ages of 60 and 80 years of age. Men are more frequently affected by the disease than women. Symptoms include difficulty in swallowing, lasting, for example, at the end of indigestion or heartburn, loss of appetite and weight loss.

The study is the only prospective study in which the actual drinking temperature of tea of trained personnel was measured. It could be a sensible measure in the field of public health, this results in all kinds of drinks to expand and to make a recommendation, that hot drinks cool before consumption is generally below 60° Celsius. Already in 2016, the International Agency for Research on Cancer (IARC) classified extremely hot drinks for over 65° Celsius as a likely carcinogen. In many countries of the world, such as China, Iran and Turkey, tea is consumed traditionally extremely hot (about 70° Celsius).
