Using iPad before bed ‘can lead to a poor night’s sleep,’ say researchers

“More and more people are taking their tablets to bed with them to surf the web, check Facebook or email before switching off the light,” Stephen Adams reports for The Telegraph. “But researchers are warning that the blueish light their screens emit can stop users getting a good night’s sleep.”

“That is because this type of light mimics daylight, convincing the brain that it is still daytime,” Adams reports. “Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours.”

Adams reports, “By contrast, light which is more orange or red in tone does not suppress melatonin production, perhaps because our brains recognise it as a cue that the day is ending.

MacDailyNews Take: Suggestion to Apple for iOS 6.1: Settings>Screen>Tint>color slider(indicate orange/red as “night” and blue/white as “day.”

[Thanks to MacDailyNews Reader “Fred Mertz” for the heads up.]


    1. When it is positive: We say tablet market
      When negative: We call it iPad

      These so called researchers should know that even a siple guy like me knows that the production of melatonin stops when there is light and starts up again when the light goes. So yes, the light from the tablet will cause the melatonin to stop, like the tv that is on in the bedroom. (you know, the thing that you wake up in the middle of the night and you discover you fell asleep watching?)

    2. “Suggestion to Apple for iOS 6.1: Settings>Screen>Tint>color slider(indicate orange/red as “night” and blue/white as “day.””

      I think there is already an app for that! lol

      Just a thought.

    1. Yeah this is what I really wanted an iPad for. I always turn down the light to a minimal good enough setting. It is a highlight of my day to be cozy in bed and have the world at my fingertips. I’ve also learned techniques where I can fall asleep and the iPad shuts itself off. What I really want is something like Dr. McCoy’s Sickbay bed reader that swings over the bed. I know there are some over-bed iPad arm things out there but haven’t bought one yet.

    1. it’s easy to call this BS for those of us who have always used our computers/laptops before we go to sleep, some of us even relying on it IN ORDER to go to sleep.

      But I think you’re missing the point.

      All of a sudden there is this incredible light weight device that we can lay comfortably with into the wee hours. The iPad will contour itself to whatever position you are in, meaning you’re likely staring at it far closer to bedtime then we as humans did before with our laptops (while versatile, still require a number of different body positions to maintain usability) or our desktops (which had us sitting in order to use them).

      The fact is, the iPad has made using ‘tech before bed’ a commonplace occurrence that most non nerds are likely unaccustomed to. More and more people are going through this process and at closer and closer to whatever our normal bed time is.

      Even if this fact is old news, or hard to credit, there is a whole new population demographic exposed to it, and in ways the laptop or desktop have never proved.

      In the end, I think MDN’s take is spot on, and I rarely agree with any MDN ‘take’.

    1. Agreed.

      I guess he’s saying that it’s worse to read and iPad (or look at porn) then it is reading a book or browsing through a Playboy like in the old days?

      The dude needs to get a life and get laid! haha
