Caffeine is a stimulant and affects our body in many ways. Though the limited use of caffeine is supposed to be a healthy stimulant for the body but increased consumption can be harmful in many ways. Limited amount of caffeine intake is supposed to make a person alert and reduces the chances of getting ailments like Alzheimer's or/and Dementia. Many people are habituated to take a cup of coffee in the morning and one in the afternoon though there are many who take many cups in a day.

A mug of coffee especially in coffee shops would give about 450 - 500 mg of caffeine to the person while a cup would be about 250 mg only. Many research scholars and clinics advise not to take caffeine more than 400 mg a day. Which means that many of us are easily and habitually crossing that threshold limit. It is evident that safe limit of consuming caffeine is only 3-4 cups a day.

Those who take more amount of coffee can have acidity in the stomach and that could lead to heartburn and other discomfort. It can also increase the blood pressure and affect the working of heart especially in people having irregular heart rhythm. Such people should consult their doctors about the consumption of coffee. Pregnant women are also advised not to take too much caffeine during the pregnancy stage. It can easily reach the placenta harming the baby's system in many ways.

Another thing is if the body becomes habitual of caffeine consumption then there are problems when we want to withdraw it due to medical reasons and a sudden withdrawal can bring many symptoms like irritability, anxiety, drowsiness, achy muscles, headache and even tremors.

Coffee if taken within the permissible limit i.e. consuming twice not exceeding the quantity 150 ml per serving would offer you some amount of health benifits such as helping the people in fighting the cases of Dementia and nerve related disorders. It can enhance mental alertness and concentration. However, in such situations the intake of caffeine should not exceed 200 mg.
Exceeding the consumption beyond the limit as stated above may cause the following side effects -
1) Mood Swings and Irratibility - If the consumption of caffeine is exceeded to the level of 1000 mg per day, it may affect our central nervous system causing mood swings and Irratibility.
2) Low Birth weight of the Baby - It has been proved by Research that the mothers in their advanced stage of pregnancy ie within 6 th to 9 th month taking 3 to 4 cup of coffee would affect the health of her infant in respect of the weight of the baby. The baby delivered may suffer from low weight as compared to mothers not addicted to such a high amount of intake.
3) Rapid High Heart Rate - The normal rate of heart is within the range of 60 - 100 and this range should be maintained at any given time. This rhythm is affected due to excess coffees consumption say consumption level goes beyond 4 cup to 5 cup daily. Heart rate often goes high immediately after taking coffee but within an hour it recedes to the normal rhythm. Exceeding its consumption in an abnormal way will shift the heart rate on the higher side.
4) Insomnia - Insomnia is associated with the excess alertness of the mind. Due to high consumption of coffee, excess stress hormone will be released affecting the normal sleep pattern.
5) Stomach Disorder due to high acidity - Frequent indulgence with the coffee especially in the empty stomach will lead to excess segregation of acid making the stomach upset such as heart - burn due to acidity or in some case, there could be manifestation of diarrhoea.

Coffee is worst than tea as per my opinion. This is my personal experience with coffee-
" I started drinking coffee during exam time to study and learn more. I thought I would be able to finish the syllabus in time if I sleep less.
But, what actually happened. After, 1 hour I started filling sleepy and dizzy after drinking coffee. I failed to complete the syllabus. I quickly washed my face with mild cold water and then started studying."
My personal experience with tea- " I certainly believe that tea works wonder in preventing you from falling sleepy. Having 2 cups of tea especially the black tea does the whole work".
People suffering from any kind of disease, aliment or undergoing any medication must consult doctors and physician before consuming caffeinated products.
