White tea, known for its refreshing and delicate flavor, is loved by many. However, regardless of how delightful tea may be, consuming it in excess can lead to some adverse reactions, such as insomnia or stomach pain. Here are some common side effects associated with white tea:
Side Effects of White Tea: Insomnia
White tea is a lightly fermented tea, made through simple wilting and drying processes. Although it belongs to the category of lightly fermented teas, it still contains a certain amount of caffeine—approximately 10-35 mg per 100 ml of white tea. Caffeine is a stimulant for the central nervous system, and excessive intake may lead to symptoms such as insomnia, rapid heartbeat, and anxiety. However, the caffeine content in white tea is relatively low compared to other types of tea (like green tea and black tea), and moderate consumption usually does not result in severe insomnia issues.
For individuals who are sensitive to caffeine, it is advisable to avoid drinking white tea in the evening to prevent sleep disturbances. Generally, drinking white tea during afternoon tea time or before dinner is a more suitable choice.
Stomach Pain
Drinking any type of tea, including white tea, on an empty stomach may cause discomfort. This is because the caffeine and tea polyphenols in tea can stimulate gastric acid secretion, increasing the burden on the stomach, which may lead to stomach pain or heartburn. Therefore, it is recommended to drink white tea after meals or during snack times to minimize stomach irritation.
Excessive consumption of white tea, especially for those with sensitive stomachs, may lead to gastrointestinal discomfort. It is advisable to consume white tea in moderation, keeping each serving to about 200-300 ml to avoid overconsumption.
Individuals Who Should Avoid Excessive White Tea
Pregnant and breastfeeding women should limit their intake of white tea, primarily due to the caffeine content, which may affect fetal and infant development. Caffeine can cross the placenta, increasing the risk of miscarriage, preterm birth, or low birth weight. In breastfeeding, caffeine intake may impact the infant’s sleep and neurological development through breast milk.
Moderate and Timely Consumption: Minimal Side Effects of White Tea
In summary, moderate consumption of white tea is unlikely to cause insomnia or stomach pain for most people. However, individuals who are sensitive to caffeine or have weak stomachs should pay attention to the timing and quantity of their consumption, avoiding drinking on an empty stomach to reduce potential discomfort. By arranging the drinking time and amount reasonably, one need not worry about the side effects of white tea.
