Written by Shruti Goenka • 

Thinking of evading boredom and gaining energy, the word ‘tea’ pops up in your mind. After water, tea is possibly the second most popular drink in the world. Today, there are different types of teas available in the market – granular, leaf, lemon tea, black tea, brick tea and even tea bags. Black tea consists of the different ingredients – caffeine, fluoride, glucuronic and lactic acid, manganese, potassium, tannin, purines, xanthine and gallic esters. When black tea first came into the market in 1827, it was considered to be a new substance and people called it theine. Its effects were quite identical to coffee and contained the same components as in coffee; since then, the word theine was given up.

For those who need to stay up late, a cup of black tea is a good thing to opt for. It accelerates the reaction time and boosts your alertness or overall concentration. This increase in alertness is the direct consequence of the stimulation of the respiratory and cardiac systems of the body; this enhances the circulation of oxygen in your body. It’s also effective in losing excessive weight. Controlling your regular appetite, it’ll curb your tendency to eat more in your daily life. What’s more, it’s an excellent way to keep away cancer. Nevertheless, excessive consumption of black tea results in a lot of side effects.

Dieticians constantly warn against excessive consumption of caffeine as they cause undesirable side-effects like insomnia, breathing troubles and increased pulse rate. Here are a few common side effects of black tea intake in excess.

Side Effects of Black Tea

Caffeine is the basic ingredient of black tea; so, if you consume it on a daily basis, it can result in diarrhoea. The reason behind this is that caffeine stimulates your digestive system.
