The blue light of the tablets, or other electronic devices, affects sleep? The problem affects all electronic devices with bright screens that any of us could use for reading before bed. Especially those suffering from insomnia.
A habit that, due to the blue light, could affect the circadian rhythms of sleep. A previous study had pointed out that the bluish light of tablets and devices for reading it could upset our sleep-related habits.
Now comes a new study on the subject, conducted by researchers from the Brigham and Women's Hospital and just published in the scientific journal Proceeds of the National Academy of Sciences. Experts compared the effects of reading from a eBook compared to the printed book.
The participants were divided into two groups. The first group was tasked with read an eBook from a tablet for four hours over the course of five consecutive evenings. The second group would read a paper book, for the same period of time and for the same duration.
Experts pointed out that the blue light effects of the tablets used iThe circadian rhythms are disrupted. As a result, the participants who read books in eBook format they took longer to fall asleep. There were also lower levels of melatonin and less attention span in the morning, immediately after waking up.
"Over the past 50 years, there has been a reduction in the average duration of sleep and its quality", - said Charles Czeisler - "As more and more people are choosing electronic devices for reading, communication and entertainment (especially children and adolescents, who already suffer from a significant lack of sleep), it is urgent for epidemiological research to evaluate long-term consequences of these devices on health and safety ".
The new research therefore confirms previous studies related to this phenomenon. Therefore, those who struggle to fall asleep should abandon the tablet - if this is the case for them - and go back to the good old book, thanks to which reading truly reconciles sleep, without any kind of technological interference.
