"Tea must be strong and piping hot!" In our society, this phrase is synonymous not just with personal preference, but with hospitality and comfort. However, the warmth we associate with freshness and solace is silently becoming a health hazard. In this special investigation by 'The FreeLance', we uncover this bitter truth. A recent study published in the 'International Journal of Cancer' involving nearly 1 million people has revealed alarming findings. According to it, consuming tea or coffee at temperatures above 65°C significantly increases the risk of esophageal cancer. Those who drink 6 or more cups of very hot beverages daily face a 71% higher risk of this cancer. Dr. Aditi Mittal, Senior Consultant in Medical Oncology at Narayana Hospital, Jaipur, explains that this habit inflicts deep internal damage over the long term.
Why is Tea Above 65°C Dangerous?
Our body tissues, especially the lining of the mouth and throat, can withstand heat only up to a certain limit. While tissues can tolerate temperatures up to 60°C for a short time, damage begins as soon as the temperature crosses 65°C. Key health risks include:
- Damage to Throat and Food Pipe: Extremely hot liquids repeatedly burn the delicate inner lining of the throat and esophagus, causing chronic irritation and inflammation.
- Impact on Oral Health: The immediate effect is often seen on the tongue, gums, and oral mucosa in the form of burns and blisters.
- Acid Reflux and Heartburn: Regular consumption of overly hot beverages disturbs the digestive system, aggravating acid reflux and severe heartburn in many individuals.
- Abnormal Cellular Growth: The continuous cycle of thermal injury and healing causes esophageal cells to grow abnormally, potentially leading to cancer over time.
WHO Guidelines and Precautions
This risk is not limited to tea alone; according to the World Health Organization (WHO), the temperature of any hot beverage, including milk, coffee, or soup, should not exceed 65°C. Dr. Aditi Mittal advises that one should never compromise their health for the sake of habits. Always let your tea or coffee cool down to a safe, drinkable temperature before consuming. A little mindfulness can protect you from severe health crises and life-threatening diseases like cancer.
