Caffeine is not good for your health

The World’s Most Widely Used Psychoactive Substance
Caffeine is the world’s most widely used psychoactive substance 
That sounds like a bad thing, but it doesn’t have to be.
Coffee, the biggest source of caffeine, also happens to be the biggest source of antioxidants in the western diet, and consuming it has been associated with various health benefits.
The second largest source of caffeine worldwide is tea, which tends to provide a moderate amount of caffeine, depending on the type.
Caffeine causes stimulation of the central nervous system, increases vigilance and reduces drowsiness.
Caffeine has several proposed mechanisms, the main one is that it is believed to block an inhibitory neurotransmitter called adenosine at certain synapses in the brain, leading to a net stimulant effect.
Adenosine is believed to increase in the brain throughout the day, building up a kind of a “sleep pressure.” The more adenosine, the greater the tendency to fall asleep. Caffeine partly reverses this effect 
The main difference between the caffeine in coffee and tea, is that tea has a lot less of it.
Whereas a strong cup of coffee can provide 100 mg, 200 or even 300 mg of caffeine, a cup of tea may provide 20-60 mg.
Bottom Line: Caffeine blocks adenosine in the brain, an inhibitory neurotransmitter that promotes sleepiness. Tea contains much less caffeine than coffee, thereby providing less stimulating effects.

The US Food and Drug Administration (FDA) state that the average amount of caffeine consumed in the US is approximately 300 mg per person per day - the equivalent to between two and four cups of coffee. This is considered to be a moderate caffeine intake, which according to many studies, can promote a variety of health benefits.
But some studies claim otherwise, even suggesting that one or two cups of coffee a day may negatively impact our health. So, what are we to believe?
We analyze the potential health benefits, as well as the negative side effects of caffeine consumption.

My advise
1...   Caffeine acts as a stimulant by activating the central nervous system. It can combat tiredness and improve concentration and focus.
2...  According to the University of Michigan Health Service, the stimulating effects of caffeine can start as early as 15 minutes after consumption and last up to 6 hours.
3...  Other than coffee, caffeine is commonly consumed through tea, soft drinks - particularly energy drinks - and chocolate. It is also found in some prescription and non-prescription drugs, such as cold, allergy and pain medication.
4...   The Mayo Clinic state that consuming more than 500-600 mg of caffeine a day may lead to insomnia, nervousness, restlessness, irritability, an upset stomach, a fast heartbeat and even muscle tremors
5.... However, previous research has linked even moderate amounts of caffeine to negative health effects.
6...  Last year, Medical News Today reported on a study suggesting that consuming 300 mg of caffeine a day during pregnancy may increase the risk of low birth weight babies, while other research suggests that drinking four cups of coffee a day may increase the risk of early death.
7,,,  It is clear that caffeine increases long time to conceive and risk to the child
8...  Any couple wish to have Healthy child should leave this habit to drink Tea or coffee.
9...  If you are habituated with coffee or tea, than drink water mixed with 2 spoons of honey and half piece of lemon juice.  It will nullify the adverse effect of tea or coffee in a couple of days.
