The analysis of the researchers of the most prestigious universities gives us a picture perhaps imaginable even with common sense that is, doing multiple things together (multitasking) does not fit. However, they add new elements, which even long-lastingly hurt the psychophysical health, the brain in the first place.

We have other times in addressed the topic from the point of view of the impact on stress, both the effectiveness and efficiency of performance. Let us therefore leave all the medical and psychological considerations to those who owe and seek instead to understand together, it is a huge deception of the idea that we have been prophesied that if we do more things together we are more efficient and effective.

How we are done?

Nature is perfect, we know it! We have been programmed in a certain way to do certain things in a certain environment. We are done to do one thing at a time. And when we do one thing at a time we’re powerful, concentrating like a laser beam. All the energies are there, devoted to a single effort, to one goal. Think of it hundreds of thousands of years ago when we were predators: like the eagle or the puma today, we were also able to be focused, with the gaze fixed on the prey. We, like the rabbits and the felines, had muscle springs ready to snap and unleash all our energies in one action. This is our nature: doing one thing at a time and dedicating soul and body to what we are doing.


In modern times everyone has been told that more things are done simultaneously and quickly, more efficient. Efficient is who gets a result with as little resource as possible. But will it be true what they told us? Will it be true that if I do more things together, how to write an act while controlling my cell phone, or writing a mail while answering a colleague, saving time? The answer is categorical: NO! It’s a dance that has propagated us. Since we are structured to do one thing at a time, what actually happens in our brain is that we continue to jump like a monkey from one branch to the other of a tree among the many stimuli that reach us: mail, messages, phone calls, demands, stresses, thoughts, worries. As you, teach one of the six laws of time, Carlson’s law: “doing an activity continuously takes less time to divide it multiple times”. So, continuing to stop the activity we are doing, even just to look at who writes us or who calls us, will lengthen the running time of the business.


Whether to be efficient means doing things with the least amount of resources, being effective means achieving the set results. Let’s ask if multitasking makes us more effective. Here too the answer can only be NO! Continuing to stop an activity we are doing involves the risk of forgetting, defeating, and defocusing the target. Therefore, continuous interruptions will only reduce our level of effectiveness and efficiency.


How does multitasking affect the stress? It is definitely a stress factor. In addition to the fact that multitasking creates a continuous sense of alert in our body, resulting in the activation of stress hormones (adrenaline and cortisol in the first place ), continuing to open new activities without closing the previous one involves greater effort and energy, higher pressure that turns into nervousness, anxiety, irritability, sense of confusion, lack of control.

Why then are we all multitasking?

The reasons are many and different from person to person, but some common reasons are:

1) By habit: Nowadays we grow in a totally multitasking context and hyper connected and we do not even notice it;

2) By necessity: For many at work it is required to be multitasking, to be always “on the piece”, to be always attainable and ready;

3) For pleasure: The superficial feeling that being multitasking involves is apparently effective and efficient, which we feel gratified;

4) For solitude: Many in this way outnumber solitude, with another kind of alienation …;

5) We like technology: For some, the use of technology is a real attraction.
