There are 9 possible negative effects of consuming excess tea, such as
1.Increased anxiety, stress, and restlessness
Tea leaves naturally contain caffeine. A cup of tea contains approximately 50 mg of caffeine. If you consume more tea, means consume more caffeine. Intake of more caffeine either by tea or any other source can lead to feelings of anxiety, stress, and restlessness. Black tea contains more caffeine than green tea and white varieties.
The longer you boil your tea, the higher its caffeine contents. It is found in research if you intake 200 mg caffeine daily, it may cause an increase in anxiety and stress. So we must restrict our tea maximum of 2 to 3 cups per day and also do not boil tea longer time. Further, if you notice the symptoms of anxiety and restlessness then reduce the intake of tea instantly.
2.Pregnancy complication
Caffeine also causes complications during pregnancy. If you intake too much amount of caffeine during pregnancy it may cause the low weight of infants or miscarriage. So it is safe to take only one or two cups of tea during pregnancy and do not take more than 3 cups of tea during pregnancy. Some people drink herbal tea during pregnancy but all herbal tea is not safe during pregnancy. Some ingredients of herbal tea can induce premature labor pain.
3.Poor sleep or insomnia
Caffeine usually disrupts the sleep cycle. So if we consume more tea, means consuming more caffeine, which will definitely disrupt our sleep cycle.
The hormone Melatonin signals our brain that it is time to sleep. It is found in research that caffeine may inhibit the production of melatonin resulting in poor sleep quality. Improper sleep is linked to various mental ailments, such as fatigue, memory loss, reduce attention span, obesity, and poor blood sugar control. The metabolization rate of caffeine differs in every person. If we intake 200 mg caffeine prior to 6 hours of bedtime, it may definitely disrupt our sleep.
4.Reduce the absorption of iron
Tea is full of tannins. Tannin can bind the iron in certain foods, resulting in it not being available for absorption in the digestive system. It may cause a deficiency of iron in our blood.
When the iron level is low and you intake more tea, it can lead to exacerbating the condition. The exact quantity of tannin in tea depends on the way of preparation. It is suggested not to consume more than 3 cups of tea in a day. Further, do not take tea after any meal because tannin available in tea can bind to iron in plant-based foods, reducing the amount that you are able to absorb in your digestive tract.
5.Nausea
Tea leaves contain tannin, which has a bitter taste. If we consume one cup of tea empty stomach in the morning it may irritate our stomach and cause nausea, it may vary from person to the person and depends on the amount of tea consumed. Some people feel this symptom by taking two or three cups of tea while others do not feel these symptoms by consuming 5 or more cups of tea. So as soon as you feel these symptoms, reduce the intake of tea immediately. You can reduce these symptoms by adding more milk to tea and taking some light snacks with tea.

The caffeine in tea may cause heartburn or aggravate acid reflux symptoms, Caffeine may relax the sphincter and allow acid to enter into the esophagus which causes heartburn. It may also increase the production of acid in the stomach.

If anybody suffers from recurrent headaches reduce the intake of beverages containing caffeine.
