That familiar feeling when the workday seems to be over, but your head feels heavy, your eyes burn, and even after a normal night’s sleep there is still no energy? Physically, it seems like you have not really been working – the whole day was spent in a comfortable chair in front of a monitor, yet by evening you feel completely drained. Most people put it down to overwork or a lack of vitamins, but the real reason lies in how our body reacts to sitting in front of a screen every day.
Just a few decades ago, data transfer was a secondary characteristic of technology. Users were more concerned with whether a device could connect to a computer at all and whether files could be copied without errors. Today, the situation is completely different.

It is important to understand that this is not about “unnecessary” information, but about its constant availability and rapid смена, which leaves no time for reflection.
