Scroll down below to find out green tea’s side effects, or precautions and warnings you need to know about.


1. Sleeping Problems

We have already pointed out the fact that just like any other tea leaves, green tea contains caffeine. So, if you are a fan of sleeping and are experiencing sleeping problems while you are enjoying your cups of green tea then you might want to cut down on those intakes. Chemicals in green tea prevent the release of melatonin which assists our body to sleep. Green tea also contains the chemical theanine, which induces calm, however, it increases our vigilance and our concentration – resulting in having troubles to sleep.

If you are drinking more than necessary then that can end in having anxiety, nervousness or shakiness.

As a side note for the people who are sensitive towards caffeine, it’s recommended not to drink green tea five hours prior to sleeping.


2. Headaches

People who are suffering from migraine should not drink green tea every day. The caffeine can cause headaches for certain people. And if you are sensitive to caffeine, withdraw from drinking green tea altogether.


3. Iron Deficiency and Anemia

Consuming too much green tea may lead to iron deficiency. This is due to the antioxidants that green tea has. Those antioxidants can halt the iron absorption in the body. This side effect is shown to be very dangerous especially for people with diseases such as anemia. In these diseases, iron is lacking, therefore, those individuals are recommended to avoid green tea consumption just as a precaution.

Some say that adding lemon to the green tea or drinking green tea before meals can help with this problem.

4. Vomiting

Drinking too much green tea may lead to vomiting. An Indian study has shown that the polyphenols in green tea can trigger nausea and vomiting. Skip drinking more than four cups of the tea every day if you are a tea lover. However, if you have just started drinking green tea, start slow and see how your body reacts to it.


5. Dizziness

Due to the caffeine in green tea, if consumed in large amounts it can cause dizziness or make you feel lightheaded. Caffeine reduces the blood flow to the brain and central nervous system issuing problems such as dizziness.


6. Breastfeeding and Pregnancy

WebMD suggests having cautious intakes of green tea while pregnant or breastfeeding. Consuming more than two cups a day is reasonably safe, however, more than that is considered to be dangerous and that is due to the caffeine. When nursing, the caffeine passes through breast milk which might have effects on the infant. Be cautious and don’t drink more than two cups a day.
