Overview:
Tea is one of the most popular and widely consumed beverages in the world. Almost in every house, people start their morning routine with a cup of tea.
Tea is renowned for its soothing properties, rich history, and myriad health benefits.
However, overconsumption of tea can negatively affect your health. Side effects of tea range from heartburn and insomnia to stress and anxiety.
The most popular varieties of tea are black tea, green tea, oolong tea, and white tea. Among teas, black tea is the most popular type of tea in the world. Approximately, 90% of the tea consumed worldwide is black tea.
Most of the side effects are caused due to the presence of tannins and caffeine in teas.

Side Effects of Tea Include:
1. Hinders Iron Absorption:
Tea is a good source of tannins. Excess tannins hinder nutrient absorption, especially iron, in your digestive tract.
Tannins can bind to iron in certain foods, making it unavailable for absorption in your body. So avoid taking teas during your meals as they hinder iron absorption.
A deficiency of iron can also lead to anemia.
2. Increases Stress and anxiety:
Tea naturally contains caffeine, like green and black tea. Having several cups of tea can cause caffeine overdose, leading to feelings of stress and anxiety.
Overdose of caffeine can also lead to headaches and dizziness. If you notice these symptoms, reduce your tea consumption.
3. Insomnia:
Insomnia is a common sleep disorder that can make it hard to fall asleep or stay asleep.
Tea contains caffeine naturally. Some studies suggest that caffeine can reduce melatonin production, disturbing your sleep quality.
Melatonin is a hormone, mainly produced by the pineal gland, that regulates your sleep-wake cycle.
4. Heartburn:
Researchers have identified caffeine as a possible trigger for heartburn in some people.
Caffeine can relax the sphincter that separates your esophagus from your stomach, allowing acidic stomach contents to more easily flow into the esophagus.
5. Increases Blood Pressure:
Excess consumption of tea leads to excess tannins in your body which can increase your blood pressure. High blood pressure can also cause cardiovascular diseases.
6. Digestive Issues:
The excess tannins, coming from a high intake of tea, can irritate the digestive system, leading to nausea or stomach discomfort in some individuals.
7. Allergic Reaction:
Though rare, some people may experience allergic reactions to tea. Symptoms can include hives, itching, and even anaphylaxis in severe cases. If you suspect an allergy, it’s crucial to consult a healthcare provider.
8. Staining of The Teeth:
Tea, particularly black tea, is rich in tannins which can cause staining of the teeth over time. While this is primarily a cosmetic issue, it can be a concern for those who are conscious about maintaining a bright smile.

However, it is important to be aware of the potential side effects of tea. Excessive consumption can lead to issues such as heartburn, insomnia due to caffeine content, and potential interference with nutrient absorption.
If you have specific health concerns or conditions, it’s always wise to consult with a healthcare provider to determine the best approach to tea consumption for your individual needs.
Moderation and mindful consumption are key to avoiding the side effects of tea.
