Drinking a hot cup of tea or coffee is one of the simplest pleasures in life. However, what many people may not know is that drinking hot beverages may increase their risk of developing cancer.

What is Cancer?

Cancer is a disease characterized by the uncontrollable growth of abnormal cells in the body. These cells form tumors that can invade and damage surrounding tissues and organs.

According to the World Health Organization (WHO), cancer is the second leading cause of death globally, accounting for nearly 10 million deaths in 2020.

What is the Link Between Hot Beverages and Cancer?

Several studies have suggested a link between the consumption of hot beverages and an increased risk of developing certain types of cancer, including esophageal cancer, gastric cancer, and oral cancer.

One study conducted by the International Agency for Research on Cancer (IARC) found that drinking beverages with temperatures above 149°F (65°C) may cause thermal injury to the cells lining the esophagus, leading to an increased risk of esophageal cancer.

Another study published in the International Journal of Cancer found that drinking hot tea increases the risk of developing esophageal cancer in people who consume alcohol and use tobacco products.

How Does Temperature Affect the Risk of Cancer?

When hot beverages are consumed, they can cause thermal injury to the cells lining the mouth, throat, and esophagus, increasing the risk of cancer in these areas.

The exact mechanism behind this increased risk is not fully understood, but some researchers believe that chronic thermal injury may cause DNA damage to the cells over time, leading to the development of cancer.

What Are the Recommended Temperatures for Hot Beverages?

To minimize the risk of cancer, it is recommended that hot beverages be consumed at temperatures below 149°F (65°C). This temperature is considered a safe limit to prevent thermal injury to the cells lining the mouth, throat, and esophagus.

Additionally, allowing hot beverages to cool for a few minutes before consuming them can help to lower their temperature to a safer level.

Other Factors That Can Increase the Risk of Cancer

While drinking hot beverages at high temperatures may increase the risk of developing cancer, there are many other factors that can also increase this risk, including:.

Smoking tobacco products
Consuming alcohol
Eating a diet high in processed and red meats
Being overweight or obese
Lack of physical activity
Exposure to environmental pollutants
Genetic factors

Conclusion

While drinking a hot cup of tea or coffee may seem harmless, the temperature of these beverages can have a significant impact on our health.

To reduce the risk of developing cancer, it is recommended that hot beverages be consumed at temperatures below 149°F (65°C). Additionally, making healthy lifestyle choices, such as avoiding tobacco products, limiting alcohol consumption, and maintaining a healthy diet and exercise routine, can help to lower the overall risk of cancer.
