People nowadays sleep less than they used to in the past. What do you think is the reason behind this? What are the effects on individuals and people around them?

leeping time are disturbing the brain.

In other words

, for better sleep, it is necessary to put away mobile phones and other gadgets for the sake of letting our brain relax and prepare for the night,

otherwise

, its activity would be continued and

as a result

, a person would have problems with falling asleep.

For example

, recent research was about two groups of people who went to the bed without disturbing by phone and another group which was using them even in the bed. the results show that in contrary to people who didn't see their devices those, who did, had problems

such

as insomnia,

hence

, slept fewer. Another thing is that individuals' effectiveness is declining due to not enough sleeping. When the body has gotten a sufficient number of sleeping hours the person would feel energetic in comparison with those who slept just for five hours. To illustrate, in Japan, where people have to work at least nine hours, scientists discovered less productivity, owing to tiredness and willingness to sleep rather than work. In conclusion, in recent centuries people slept more than nowadays. I reckon that usage of electric devices disturbing us,

moreover

, it has a harmful impact on the person's productivity.
