1. Preferring New Tea
Since new tea has a short storage time, it contains more unoxidized polyphenols, aldehydes, alcohols, and other substances, which have a strong irritating effect on the gastrointestinal mucosa and can easily induce stomach problems. Therefore, new tea should be consumed sparingly, and tea stored for less than half a month should be avoided.
2. Drinking the First Brew
Due to pollution from pesticides and other harmful substances during the cultivation and processing of tea leaves, there is always some residue on the surface. Therefore, the first brew has a cleansing effect and should be discarded.
3. Drinking Tea on an Empty Stomach
Drinking tea on an empty stomach can dilute gastric juice, reduce digestive function, and increase absorption rate, causing harmful components in tea to enter the bloodstream in large quantities, leading to symptoms such as dizziness, palpitations, and weakness in the limbs.
4. Drinking Tea After Meals
Tea contains a large amount of tannic acid, which can react with iron in food to form new substances that are difficult to dissolve. Over time, this can lead to iron deficiency in the body and even induce anemia. The correct method is to drink tea one hour after a meal.
5. Drinking Tea During a Fever
Tea contains theophylline, which can raise body temperature. Drinking tea for fever patients is like "adding fuel to the fire."
6. Ulcer Patients Drinking Tea
Caffeine in tea can promote gastric acid secretion, increase gastric acid concentration, and induce ulcers or even perforation.
7. Drinking Tea During Menstruation
Drinking tea during menstruation, especially strong tea, can induce or worsen menstrual syndrome. Medical experts have found that compared to non-tea drinkers, habitual tea drinkers have a 2.4 times higher probability of developing menstrual tension syndrome, and those who drink more than 4 cups a day have a 3 times higher risk.
8. Sticking to One Type
The climate varies across the four seasons, and the types of tea consumed should be adjusted accordingly. Spring is suitable for flower tea, which dispels cold and promotes vitality; summer is suitable for green tea, which clears heat and aids digestion; autumn is suitable for oolong tea, which balances internal heat and refreshes the mind; winter is suitable for black tea, which provides warmth and nourishment.
