The study was organized by Peking University College of Public Health, and the research team investigated the relationship between the risk of esophageal cancer and high-temperature tea drinking among Chinese residents. Researchers have followed up more than 450,000 China adults aged 30-79 for an average of 9.2 years, and analyzed the data. During the investigation, 173 1 participants were diagnosed with esophageal cancer.
The results show that the lifestyle habits of smoking and drinking hot tea are positively correlated with the risk of esophageal cancer. Specifically, compared with peers who don't drink alcohol, tobacco and hot tea, participants with the above three habits have a five-fold increase in the risk of esophageal cancer; People who are only exposed to tobacco and alcohol and often drink hot tea will also face a higher risk of cancer. The study was published in the American Annals of Internal Medicine.
The researchers pointed out that previous studies have found that chronic thermal injury of esophageal mucosa will increase the risk of cancer. Hot tea burns the esophagus, which itself increases the risk of cancer. In addition, hot tea damages the ability of esophagus to resist alcohol and nicotine toxins, so smoking and drinking hot tea are more likely to get sick. Experts suggest that you should drink less hot tea or coffee above 65 degrees Celsius. If you have difficulty swallowing, persistent indigestion or heartburn, you will feel sick just after eating, and you should seek medical advice promptly.
