Scientific research proves that a smartphone negatively affects a person’s condition both during work and during leisure. First of all, we actually use this gadget longer than we think: 5 hours on average daily, and it feels like 2.5 hours.
Also, when we are often distracted by a mobile device, our concentration deteriorates. This is due to the fact that the brain needs 23 minutes to fully concentrate on something, and if you check your phone every 5 minutes, then there is no time left for concentration.
Finally, an important fact: “flipping the tape” is not a rest for the brain at all. A person is able to either rest or process information. That is, watching YouTube videos after work will only overload the brain even more.
