Too much time spent in front of the screens in the evening
Over the past decade or so, the amount of time spent in front of screens in the evening before bedtime has been increasing among teenagers.
However, what has changed is the media used: TV is almost completely abandoned in favor of computers and especially smartphones.
The concern is that the brightness of these new screens has a significant effect on the retina because it mimics the brightness of the day: the internal clock of teenagers is disturbed because the brain thinks that the night has not begun and, as a result, it does not send the first signals of sleep.
The longer the time spent in front of the screens, the more this effect is important and the more sleep is delayed!
Connections in the middle of the night
The worst thing is that 15% of young people send text messages in the middle of the night, while 11% connect to social networks!
Adolescents are completely unaware that in order to sleep well and recover well, they need to go totally “off”, no longer stay alert and forget about the stimuli of daytime life.
What is even more disturbing is that these nocturnal connections are often scheduled as early as bedtime: an appointment has been set up in the middle of the night with friends, without the knowledge of parents who are totally unaware of this nightlife.
Obviously, this nightlife has disastrous consequences on the quality of the following day: 23% of college students are drowsy or fall asleep in class!
These late sleeps and nocturnal awakenings obviously lead to very difficult waking for 30% of our teenagers.
On average, 27% of young people lack 2 hours of sleep per night during school hours.
We therefore observe an increasingly important encroachment of activity on sleep time. However, sleep is essential to be able to recover and be effective the next day. This is particularly detrimental during this period of life when the personality is being built and learning is taking place.
Parents, it’s up to you
In light of these alarming numbers, it is important for parents to become aware of the problems their children are experiencing and to help them disconnect by giving them bedtime instructions.
Parents are also advised to ask their children to leave smartphones and tablets out of their room at night: there will be less temptation to send text messages if they have to get out of bed in the middle of the night!
