Tea is the favourite early morning beverage for many to kick-start their day. It comforts you on a rainy day and acts like a medicine during sniffles and slight fever. But, there is a dark side of your favourite drink. There is no harm in sipping one or two cups of tea in a day but excessive consumption of tea has its own side effects. But, don't let your habit turn an addiction.

Commonly called as 'Chai' in India, the hot drink can cause serious health problems if taken in uncontrolled proportions.

Check out below some of the side-effects of tea that will compel you to think twice before going for the third cup in a day:

Dehydration and constipation

While many believe morning tea helps in a smooth bowel movement, people aren't quite aware that excessive consumption will cause constipation. Because, a chemical present in the tea, Theophylline, causes dehydration which in turn leads to constipation.

Prostate cancer

Tea is not good for prostates either. According to a research by the University of Glasgow, it was found that men who drank seven or more cups of tea in a day had 50 percent higher risk of prostate cancer.

Nutrient deficiencies

Excessive consumption of tea may lead to nutrients deficiencies in the body because it hinders absorption of essential nutrients such as iron by the body. Some studies show that black tea decreases body's iron absorption.
