Whats the first thing you do in the morning after you wake up? Nine out of ten Americans will answer a few things like wash my face, take a shower and... have a cup of my favorite coffee.
In case youre really late for work and dont have time for this, I have another question: What do you do first when you arrive at the office? Again, nine of ten will have answers like turn on my computer, get ready for work (various ways) and... have a cup of coffee.
If you stop and think about it, coffee is the most popularly consumed product in the world. Over 50% of US population drink coffee every day, with an average of three cups a day. Each year, over 500 billion cups of coffee are consumed all over the world. If we take a vague, very vague average number of $3 per cup, thats about $1.5 trillion revenue each year. Thats insane. When it comes to commodities, coffee is second to none other than oil. This means that coffee has more worldwide demand than every other product including bread and meat.
People say (and I was one of those until I started using this nice thing called logic) that a cup of coffee helps them get their day going, get on top of things, improve memory, be more attentive, sharpen senses and so on, in other words increase productivity. This is so incomprehensibly brilliant, I cant help but admire the people who gave this idea to the general public. Lets get to the core of things.
What people refer to when they list all these benefits they get from coffee, in reality comes from caffeine. Caffeine is the most popular psychoactive drug in the world. Whats interesting here is that caffeine, when used seldom and in small dosages, can have some or all of the above mentioned effects on the human body, but its not the same with each person. It depends on a ton of stuff including, height, weight, age, sleeping cycle, etc.
This means that while it is technically possible to enhance your senses with the help of caffeine (which is, by the way, an ingredient of most energy drinks, carbonated soft drinks and teas apart from coffee, so its essentially EVERYWHERE), but a drug is still a drug. Its just not banned out, since it doesnt have so many side effects.
If you dig a bit deeper, you will find hundreds of people complaining about coffee and saying they have jitters, crashes and headaches after they have a cup. Yes, excessive amounts of caffeine can have a negative effect on you.
The safe amount of daily caffeine intake is about 300-400 mg (max) to get through the day with no side effects. Thats about 1-4 cups of coffee a day (depending on what coffee you drink, for example one cup of Americano at Starbucks contains 75-300 mg per cup). This is already alarming, since average consumption of coffee is about three cups a day. And lets just not forget that caffeine is also contained in most sodas and teas. So if you are a Starbucks fan and also a Coke fan at the same time, thats not very good.
What do we gather from all of this?
Getting back to productivity. While caffeine can give some people a productivity boost, it doesnt mean that other people cant get the same level of productivity without it. Even so, after you drink two cups of coffee, another cup isnt going to accomplish much. In fact, it may have an opposite effect in most cases, like headaches, disturbance, lack of attention, etc. There is absolutely no physical or chemical proof to the phenomenon that coffee increases productivity.
Given this though, people still insist on the matter that coffee is essential for them. This is called the placebo effect. There is a theory in psychology that if a person truly believes something, the brain and organism may have the positive response, or rather the anticipated response to it. People think that drinking coffee will increase their productivity and as a result, most of them feel, or at least they think they feel, a surge of energy and a productivity boost.
Coffee is still awesome!
While there is no scientific proof that coffee increases productivity, it still does a lot of good. Some people also find it easier to communicate with their teammates or clients while drinking coffee (I do that every day), or getting more closed deals or really, just drink it for the sweet taste and entertainment. When it comes to relaxation and entertainment, these two can boost productivity by a lot, maybe not scientifically, but its the end result that matters.
A good mood and friendly atmosphere is no less valuable than scientific studies. A few cups of coffee during a friendly meeting can bring so many good ideas that might not have been generated otherwise. This is why Apple has a coffee shop inside their territory, so potential great ideas dont get out.
What I am trying to say, you can and should still drink coffee, since its such an important part of our life, but when you are feeling tired or need to focus, dont rush straight for that third cup of caffeine, which may harm your health. Health is important, trust me, I am a doc:) Take a short break, go for a walk, wash your face, have a chocolate bar, there are countless things you can do apart from another coffee shot.
Now you know
Now that you know all of this, the next time you hear somebody say that coffee increases productivity, you should drink it to be more productive, etc. tell him or her to stop promoting the coffee market (I mean, its already insane, doesnt need any more help) and show this article.
If you like coffee, go ahead and drink it, but make sure not to pass the daily limits. If it helps you relax or socialize with your teammates, its great! When it comes to productivity though, you might get as much productivity as you would with a glass of water or orange juice.
