People who use their computer, tablet or smartphone before falling asleep more often suffer from sleep disorders, according to the results of the investigation INSV / MGEN “Sleep and new technologies” announced at the occasion of the 16th sleep Day, this Friday, March 18, 2016.
49% of those with a computer running or on standby in their bedroom have trouble sleeping, against 36% of the French population, according to results of the survey ” sleep and new technologies “conducted by the National Institute of sleep and Alertness (INSV) MGEN and revealed on the occasion of the 16th Day of sleep, March 18, 2016.
young adults, fond of new technologies, are particularly concerned about the deleterious impact of “screens”. Indeed 18-34 years are more likely to be sleepy during the day. They also spend more time in bed before turning off their lights (36 minutes on workdays and 39 minutes on days of rest, against 27 minutes on average) and take longer to fall asleep (24 minutes against 21 minutes on average). Moreover, they are more likely to suffer from at least one sleep disorder.

Thus, 10% of respondents admit to being awakened by messages received overnight. 92% of them consult upon receipt and 79% answer spontaneously. Recall that the light signals emitted by the screens disrupt the biological clock which makes it incapable of ensuring the conditions for rapid sleep onset or sleep.
Bright millisecond flashes at night may delay the biological clock, and the system is so sensitive that the light is even if sleeping eyes closed , says Dr. Claude Gronfier, neurobiologist and expert biological rhythms.
added to this is the use of increasingly frequent and prolonged screens during the day. 46% of French indeed spend more than two hours per day in front of their computer screen for personal needs, 25% more than four hours, which helps to stay alert and connected as possible … including night. As stated Dr. Sylvie Royant-Parola, psychiatrist and vice president of INSV,
regardless of the age of technology aficionados and regardless of the connected object, new technologies have given birth to a society on the alert, where everyone is on deck, both day and night. People do not realize that sleep needs protection to install and night must be a totally disconnected time, a total break time of the environment .
Change sound behavior for better sleep
It is possible to improve the quality of sleep by changing their habits and behavior. These include not to expose the screens at night in bed, ignored the new technologies at least 1:30 before bed, banish from room phones and smartphones or learn to disconnect the rest days. In addition, applications can reduce the percentage of blue light emitted by smartphones and tablets from a certain time. Remember that blue light impacts the nocturnal production of melatonin, the hormone that regulates our rhythm sleep / wake. However habits that are a little more complicated to adopt when working at night or shift work …
