Lack of sleep can be a problem caused by drinking too much green tea, especially if it is done in excess or late in the evening. The main cause?Caffeine. It stimulates the nervous system and can interfere with sleep. Pregnant women or nursing women should avoid drinking green tea or, at least, drink it in moderation, to avoid insomnia.


One way to get rid of this problem is to reduce the amount of green tea you consume daily. Moreover, avoid drinking it on an empty stomach.

It can cause allergies

The most common green tea-related allergies are eczema and urticaria, and its sensations can be felt on the face, lips, tongue or throat.

Frequent urination
