Although green tea normally has lower levels of caffeine than coffee, it can still be sufficient to induce headaches in some individuals. Furthermore, headaches could be connected to other elements in green tea, such as tannins. It is essential to note that not everyone will experience headaches after drinking green tea, and the intensity of the headaches may differ depending on the person.

There are also a few other considerations if you are dealing with headaches after consuming green tea. For instance, drinking green tea on an empty stomach may raise the risk of headaches and other gastrointestinal distress. Additionally, brewing green tea too strongly or leaving it too steep for too long may also add to headaches and other side effects.
