Three Harmful Tea-Drinking Habits to Avoid
Green tea has long been known for its many health benefits, such as antioxidant properties, cardiovascular support, and reducing cancer risks. However, consuming tea incorrectly can harm the body, particularly the kidneys, stomach, and even increase the risk of cancer. Below are three common tea-drinking habits that many people unknowingly follow, which can be detrimental to their health.

1. Drinking Overnight Tea
Many people have the habit of brewing tea and leaving it overnight to save time. However, leaving tea for too long can lead to oxidation, loss of flavor, and depletion of beneficial nutrients. Additionally, overnight tea can become a breeding ground for bacteria, increasing the risk of food poisoning. Therefore, it is best to drink tea immediately after brewing and avoid letting it sit for extended periods.
2. Drinking Tea That Is Too Hot (Above 65°C/149°F)
Consuming excessively hot tea can damage the mucous membranes of the mouth, esophagus, and stomach. According to the World Health Organization (WHO), drinking beverages hotter than 65°C (149°F) may increase the risk of esophageal cancer. To protect your digestive tract, allow tea to cool slightly before drinking.
3. Drinking Tea That Is Too Strong
Overly strong tea contains high levels of caffeine and theophylline, which can overstimulate the nervous system, causing insomnia, rapid heartbeat, and high blood pressure. Additionally, strong tea can irritate the stomach lining, leading to gastritis or worsening existing ulcers. To protect your health, brew tea at a moderate strength and avoid excessive consumption throughout the day.
Tips for Safe and Healthy Tea Drinking:
✔ Brew Tea Properly: Use water at around 80-85°C (176-185°F) when brewing green tea to preserve its flavor and nutrients.
✔ Consume in Moderation: Limit intake to 2-3 cups per day to enjoy the benefits without harming your body.
✔ Avoid Drinking Tea on an Empty Stomach: Drinking tea on an empty stomach can irritate the stomach lining. It’s best to consume tea 30-60 minutes after meals.
By being aware of and changing these unhealthy tea-drinking habits, you can maximize the benefits of tea while protecting your health.
