Not tea or coffee, its boiling temperature increases the risk of cancer! WHO and global research revealed; Know at what temperature it is safe to drink


Starting the morning with a cup of strong tea or sipping hot coffee while working is an important part of the Indian lifestyle. Many people are used to taking a sip while steam is coming out of the cup. If you also have this habit, then be careful. Extensive studies by international health researchers and IARC (International Agency for Research on Cancer), the cancer research agency of the World Health Organization (WHO), have made it clear that the danger lies not in the elements of tea or coffee, but in its extremely high temperature.

According to research, regular consumption of beverages with a temperature of 65 degrees Celsius or more increases the risk of esophageal cancer by almost double.

The inner layer of the food pipe (Esophagus) is made of very soft and sensitive mucosal cells (Epithelial cells). When a person continuously swallows very hot liquids, the following processes occur within:

  • Thermal burns and micro wounds: Tea or water hotter than 65°C scorches the delicate inner wall of the food pipe as soon as it enters the throat, causing micro blisters and irritation there.

  • Chronic Inflammation: If a person drinks boiling tea 3 to 4 times a day, these cells do not get time to heal and there is a state of constant inflammation.

  • Mutations in cells: During the repeated burning and rapid self-repair process, the cells’ DNA begins to get damaged. This uncontrolled cell repair later takes the form of cancerous tumor.

  • The Lancet Oncology reports: In the report published by IARC, Very Hot Beverages above 65°C Group 2A Carcinogen (Potentially carcinogenic to humans).

  • International Journal of Cancer study: A 10-year study of more than 50,000 people found that people who drank 700 ml (about 2 large mugs) of tea daily at a temperature of 60°C or higher had a lower risk of esophageal cancer than those who drank normal or lukewarm tea. up to 90% more Found.

  • Double the risk with smoking and alcohol: Researchers have warned that in people who consume cigarettes, beedis or tobacco with hot tea-coffee, this risk increases by 4 to 5 times, because the burnt food pipe absorbs the toxins of tobacco more rapidly.

It is not at all necessary for you to give up your favorite tea or coffee to prevent cancer. Just make these simple changes to your drinking style:

  • ‘Cooling Time’ of 3 to 5 minutes: Wait for at least 3 to 4 minutes after pouring tea or coffee into the cup. In this time its temperature reaches safe level i.e. 50°C to 58°C Comes between.

  • Benefits of adding milk: If you drink light milk instead of black tea or black coffee, the temperature immediately comes back to normal levels.

  • Steam and the rule of the first sip: If steam is coming out rapidly from the cup and it is difficult to hold the cup with your hand, then do not hold it directly to the lips.

  • Kulhar or wide mouthed cups: Wide-mouth cups cool drinks faster, reducing the risk of scalding.
