Pros and Cons of Caffeine

According to the studies, about 80% people around the world consume caffeine each day. Most people rely on caffeine to increase their concentration and productivity. Tea, coffee, and various energy drinks contain caffeine in different concentrations. Other than beverages, caffeine is also present in chocolates. Daily consumption of caffeine can have both beneficial and harmful effects on health.


Helps to Focus

As a brain stimulant, caffeine helps to maintain focus and to stay alert. It enhances the overall brain functioning and helps increasing productivity and motivation.

Reduces Fatigue

Caffeine helps in increasing energy levels and reduces fatigue. However, consuming more than 400 mg per day can have the opposite effect.


Caffeine is not among those drugs which cause addiction, neither does it give rise to any serious health issue. However, it causes physical dependence.

Health Benefits

Studies show that a moderate amount of caffeine may have health related benefits against cardiovascular disease, liver cancer, skin cancer, Parkinson’s disease, Alzheimer’s disease, kidney stones, type 2 diabetes, etc.


Withdrawal Effects

Withdrawal symptoms arise if there’s a sudden stop in caffeine intake which commonly includes headache, irritability, tiredness, difficulty concentrating, fatigue, and depression.

Induces Insomnia

Caffeine is a compound that keeps you awake which in contrast would contribute to disrupted sleep. Caffeine intake within 6 hours of going to bed can interfere with sleep.


Caffeine overdose can increase anxiety. As a stimulant, caffeine can activate the sympathetic nervous system (aka ‘fight or flight’ response) which, can contribute to anxiety and nervousness.

Increases Blood Pressure

Caffeine can increase blood pressure by stimulating the sympathetic nervous system. People with high blood pressure should consume caffeine carefully.


The Food and Drug Administration (FDA) recommends a maximum intake of 400 mg a day or 2-3 cups of coffee. Through studies we know, that a reasonable amount of caffeine can also increase life expectancy. Caffeine is good for health only if it is consumed in a moderate amount as recommended by FDA. Overdosing of caffeine can produce undesirable effects.
