Seriously, stop using your smartphone in bed

Excerpt from this article:

It’s an inconvenient truth for an increasingly connected (and addicted) world, but LED screens are the enemies of sleep. A steady trickle of 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 recorded their sleep patterns as well as their technology usage throughout the day, with a focus on the hour before bedtime. The result? What researchers call a “dose-response relationship” — 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.”

Rationalize it all you want — a quick game of Candy Crush will relax me! — but the numbers don’t lie.
