New e-reader update to enable better sleep
If reading your ebooks late into the night is costing you your health then Amazon may have the solution
It's a known fact that staring directly into a bright screen can mess up your sleep, but Amazon has come up with a way to make sure its tablets don't make you toss and turn.
The tech company's latest soft ware update for its Fire tablets brings out `Blue Shade', a feature which reduces brightness and the amount of blue light a screen shines onto your eyes. This gives the screen a warmer orange tint that not only goes easier on the eyes in low-light settings, but could also improve the way you sleep.
The health detriment of late-night electronics are common knowledge, but Harvard Health Publications finds that blue light, given off by most LEDs, electronics screens and energy-efficient light bulbs, can be especially bad.
“Not all colours of light have the same effect,“ said Harvard in their online health letter. “Blue wavelengths, which are beneficial during daylight hours because they boost attention, reaction times, and mood, seem to be the most disruptive at night.“
`Cool' blue light, in contrast to the `warm' contrast to the `warm' or a n g e -yellow given off by in can descent light bulbs or fire, can disrupt internal clocks.
Late-night exposure to blue light can also reduce production of melatonin, a hormone critical for getting a good night's rest as it helps regulate your circadian rhythm. Blue Shade was not the only feature that came with the Fire's latest update. Among other changes, improved parental controls were added to help guardians choose what functions are avail .able to their children and how long they can be accessed
