Iranian researchers have published studies that show that drinking a cup of hot tea every day is likely to increase the risk of esophageal cancer. Moreover, when the water temperature of tea is between 5°C-0°C, the risk of esophageal cancer doubles, and once the water temperature of tea exceeds 0°C, the incidence of esophageal cancer increases by 0 times. If the tea is consumed within 0 minutes after pouring, the risk of esophageal cancer will increase by about 0 times compared with waiting for 0 minutes before drinking it.

Another study has found that when drinking tea, the temperature of tea is between 60°C-0°C, which is more beneficial to health.
