Covid-19, this is how much insomnia weighs from tablets and smartphones

The pandemic has changed our habits by multiplying the use of electronic devices: a research has evaluated the effects on sleep quality

Experts recommend it. Pay attention to the exposure to "blue" light from electronic devices, especially in the evening but not only. The quality and in some cases also the quantity of sleep is at stake. Those who find it difficult to fall placidly into Morpheus' arms should really be careful not to overdo it with tablets and smartphones. This is recalled, once more, by a study published in Sleep and conducted in Italy, in the first period of lock down, when the volume of traffic on the network almost doubled compared to the previous year.

A two-stage survey

The research published in Sleep was conducted by scholars from the Laboratory of Sleep Psychophysiology and Cognitive Neuroscience of the Department of Applied Clinical and Biotechnological Sciences of the University of L'Aquila. Over 2,100 Italians were examined in the third and seventh week of "closure", with tests on the quality of sleep and disorders related to insomnia. In the second phase, the use of electronic devices in the two hours before closing the eyelids was studied in particular, together with the classic questionnaires. According to the analysis, in over nine out of ten people the lock down led to an increase in smartphones and tablets near the time of night rest.

Those who developed this trend generally reported a decrease in sleep quality, an increase in insomnia symptoms, shorter total sleep times and times to go to bed and get up later. Furthermore, the scholars found more cases of subjects who sleep badly and of respondents with moderate to severe symptoms of insomnia only within this group of respondents. On the contrary, those few who instead limited and even decreased the time spent in front of the screens between the first and second survey found an improvement in the quality of sleep and fewer annoyances related to insomnia, even going to rest earlier. Finally, those who have not changed their habits in terms of using devices have not had repercussions on the quantity and quality of sleep, which in some cases has even improved.

Beware of habits

In short, even light, like stress and other factors, affects the quality of our sleep because the system that regulates it is very delicate. Alterations in normal habits, stress, anxiety, fears for the future can heavily affect the quantity and quality of night's rest. We take care to avoid information excesses and not to stay for hours in front of the TV or tablets and smartphones. But above all let us remember that physical activity, better if not just before bedtime, is of great help to "tire" the body.

And then, especially in this season of "reopening", we remember that it is always important to go to bed in the time slot our body is used to: if we normally rest shortly after dinner, we must continue to behave in this way, as if we are "Night owls" we must not anticipate too much in an attempt to counteract insomnia. And let's not forget that this, like other studies, show a correlation between the habits of staying fixed in front of tablets and smartphones with the risk of sleeping little and badly. Let's get used to moderation.
