This is all about risk. All of us have been taking risks from cradles into adulthood – we know, only, what we think that we know about ourselves, the society and humanity: science, which is the tool of discovery for human knowledge, now, seems to be confused (itself).
How on earth would science says that an apple a day keeps the doctor away and still turn around to warn you about eating apple in another time? Well, the confusion we used above is non–literal, because, for the records – science has helped us to discover the world beyond our natural abilities.
Our main focus (in this article) is to talk about the time, that is safe, for the consumption of coffee. Unarguably, people from different quarters had spoke against caffeine substance in coffee and had warned of its excessive use: various reports still encourage its consumption, but borrowing from the Holy Writ ‘moderation’ should characterise one’s use of coffee.
In a recent BBC article, the coffee break or not to break issue was shown to be a hot one with British office workers and bosses. Statistics of various aspects of office protocol dealing with taking a break from work to sip a warm drink were mixed into the discussion. Apparently, workers in Britain are well behind US workers when it comes to the revered American coffee break.
Also, recently, an occupational psychologist was quoted as recommending that companies should provide morning coffee breaks twice a week, for which workers would be encouraged to leave their desks so they could chat over free hot drinks.
This is one of the confusions that science causes
In two new studies published in the Annals of Internal Medicine, researchers delved into the coffee– drinking habits of more than 700, 000 people in the US and in 10 European countries. The scientists were, particularly, interested in looking at death rates among people of non– white populations. In both studies, people in these groups who drank more coffee tended to have a lower risk of dying (during the study period) than those who drank less coffee, or no coffee. 
We wish to caution our readers that we are not giving license to the use of coffee, rather, individual’s discretion should be used in coffee consumption.
The studies show that regular java drinkers have a lower risk of diabetes, fewer strokes and heart problems, as well as, lower rates of certain cancers. All of that may help explain why coffee drinkers also tend to live longer than people who do not drink the brew.
Whereas, health practitioners are (vigorously) warning people on the constant intake of coffee – these reports are telling us that long life could be connected to coffee (which is highly rich is caffeine).
No matter what, consumption time is key
Drinking a cup of coffee first thing in the morning blunts the energy–boosting effects of caffeine and may lead to increased tolerance of the stimulant.
According to Anthony Kosner, everybody is different, of course, but we are all guided by the 24–hour hormonal cycle referred to as the circadian clock. These basic rhythms are preprogrammed into us genetically and, although, we can mess with our cycles through lifestyle habits, the major factor in their regulation is sunlight. One of the things that this clock controls in humans is the release of the hormone called cortisol which makes us feel alert and awake.
He explains further that the peak production of cortisol occurs between 8–9 am (under normal circumstances.) This means that at the time that many people are having their first cup of coffee on the way to work, their bodies are actually “naturally caffeinating” the most effectively!
Quoting Ryoko Iwata from her blog titled ‘I Love Coffee’, Kosner said, “The effects of caffeine consumption at times of peak cortisol levels actually diminishes the effectiveness of the additional stimulation. By consuming caffeine when it is not needed, your body will build a faster tolerance to it… buzz you get will greatly diminish”.
In conclusion, a person does not need a prophet to tell him that his/her health is deteriorating once the person’s body starts to resists the caffeine effect of coffee (either due to abusive use or wrong time consumption).
So, watch it!
 COFFEE KIND, MUCH ADO ABOUT THE COFFEE BREAK.
