If your having too much coffee in a day, you must have to remember that you're not only consuming coffee or enjoying it's taste, but also consuming a lot of caffeine as well.

A single cup of coffee (8 fl Oz) of coffee contains about 95mg of caffeine. Studies shows that 400mg of caffeine everyday is too much and is the safe dose of caffeine (link). Means 4cups of coffee can give you approximately 400mg of caffeine.


So, lets take a look, how too much caffeine can degrade your performance of work and your health.

1. Too Much Caffeine May Cause Insomnia

People with hypertension were given 250 mg of caffeine (about 2 coffees) and the data revealed that their blood pressure was elevated for about 2-3 hours after the caffeine. (Link)

A second study performed by The Mayo Clinic found similar results from a 160 mg dose. All participants experienced a marked rise in blood pressure and it was the most pronounced in those that didn’t normally consume caffeine.
