It happens to us all while browsing Facebook you notice a post where your Facebook friend is complaining that he can’t sleep and the next thing you will notice is that he did it at 1 a.m. so first thing that comes to your mind will be to write him a comment like:
“Maybe stop staring at a screen, dummy.”
Then you stop and think that it’s 2 a.m., you’re reading Facebook posts from a smartphone in bed, and ask yourself who is dummy now…
It’s an inconvenient truth for the ( addicted) world, but you must know that LED screens are the enemies of sleep. Studies confirm this, the latest being a survey of 9,846 teenagers aged 16 to 19 in Norway, two years in the making and published Monday in the medical journal BMJ Open.
The teens made notes for their sleep patterns and technology usage throughout the day, with a focus on the hour before bedtime and came to a conclusion that the more you dose yourself with devices, the higher your risk of sleeplessness.
“Almost all adolescents reported using one or more electronic devices during the last hour before bedtime,” the Norwegian scientists wrote. “Extensive use of these devices was significantly and positively associated with SOL [sleep onset latency, or the amount of time it takes to nod off] and sleep deficiency, with an inverse dose–response relationship between sleep duration and media use.”
Some studies showed that blue light emitted by all LED screens interferes with the production of the sleep hormone melatonin in the brain.
That might be the reason for the popularity of apps like Twilight for Android, which promises to “harmonize your screen with the sun cycle” — automatically lowering brightness at night.
Twilight has over 74,000 positive reviews in the Google Play store.
Norwegian researchers suggest that electromagnetic radiation may also be stopping us from getting a good night’s rest. The hunched-over can lead to headaches and muscular pain.
“There are probably multiple pathways explaining the associations between sleep and electronic devices,” the study says. “Media use may directly affect sleep by replacing it due to its time-consuming nature, or may interfere with sleep through increased psychophysiological arousal.”
So it’s using your smartphone and why you are using them matters ,even a simple game can raise your heart rate and induce the fight-or-flight response.
Until more researches and studies are made get a Kindle device (although even the lowest brightness setting on the Kindle Paperwhite can be a little on the bright side).
Reading on a phone or tablet isn’t the best idea so try getting a good privacy screen for the mobile device that reduces glare. Fire up Kindle or iBooks in night mode, then turn the brightness all the way down.
The best is to manage to resist the urge to check Facebook so good luck with that …
