Drinking New Tea
Many people love the fresh and brisk taste of new tea. Besides its pleasant aroma, it can help refresh the mind and promote airflow. However, its side effects should not be ignored. New tea contains a high amount of unoxidized polyphenols, aldehydes, and alcohols, which strongly irritate the gastrointestinal mucosa and can easily cause stomach problems. Those with weak stomachs should pay extra attention. New tea should be stored for at least a month before consumption.

Drinking Tea on an Empty Stomach
Many people believe drinking tea on an empty stomach can help with weight loss, but they are unaware that it causes significant harm to the stomach. It can easily lead to symptoms such as dizziness and weakness in the limbs. It is better to pair tea with some light snacks.
Drinking Tea Immediately After Meals
Drinking tea right after meals is a common habit among tea lovers. Over time, this may lead to iron deficiency anemia. Therefore, it is best to drink tea at least one hour after a meal.

Drinking Tea When Having a Fever
The theophylline in tea can raise body temperature. Drinking tea during a fever only makes things worse, like "adding fuel to the fire."
Drinking Tea During Menstruation
Many women have the habit of drinking tea during their menstrual period, thinking that a warm cup of tea feels soothing. However, this is a mistaken habit. Especially strong tea may trigger or worsen discomfort during menstruation.
