New study shockingly debunks science behind iOS and Android feature

New study shockingly debunks science behind iOS and Android feature
You might remember that Apple first included the Night Shift feature in iOS 9.3. Enabling Night Shift removes blue light from an iPhone and iPad display making the colors on the screen warmer. At the time, studies indicated that blue light strains the eyes and throws off a person's 24-hour sleep-wake cycle. When turned on, Night Shift and the Android version (called Night Light) give the display a yellowish tint.

We don't know how many of you swear by Night Shift or Night Light in order to get a good night's sleep, but a study conducted by scientists at the University of Manchester (via Android Police) reveals that blue light might not disrupt sleep patterns as the earlier studies concluded. The report flips the old findings by stating that "using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial to our health." As proof, the researchers note that twilight is dimmer and bluer than daylight and the body's internal clock uses both of those "features" to determine when to be awake and when to be sleeping. The original research from 2015-2016 said that using warmer colors at night was more beneficial.

The University of Manchester scientists said that Night Shift and Night Light, by limiting users' exposure to blue light, might be sending the body mixed messages. The researchers used mice for their test along with special lights that can change colors but not the brightness. What they found was that blue lights have a weaker effect on a mouse's body clock than yellow light. The team's Dr. Tim Brown said, "We show the common view that blue light has the strongest effect on the clock is misguided; in fact, the blue colors that are associated with twilight have a weaker effect than white or yellow light of equivalent brightness."

If using Night Shift or Night Light makes it harder for you to fall asleep at night, your response is confirming what the researchers at the University of Manchester have found. Dr. Brown states, "Our findings suggest that using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial. Research has already provided evidence that aligning our body clocks with our social and work schedules can be good for our health. Using color appropriately could be a way to help us better achieve that."

Regardless of whether you use iOS or Android, give this theory a try tonight. Disable Night Shift or Night Light and see if you get a better night's sleep.

Shows the follow the pack mentality of humanity on this planet. Anything written in bold letters, anything too visible and anything that's been said by a reputed co. Is God's word for them / us. We're great followers.

No you sir are ignorant and don't know what you're talking about. Blue light is in fact far more harmful than green or red light. Look into Laser safety and you'll come to realize that blue lasers at identical power levels to red and green lasers are far more harmful and can cause severe eye damage much quicker than the other 2. Just because one incredibly flawed study mentions that blue light is better for your sleep compared to many others who say the opposite doesn't mean it's automatically true. You seem like the person that is complete opposite to the sheep. You go against anything that is popular just to be against the popular out of spite. The pack mentality is real and most humans on this planet are downright stupid, however that doesn't mean that what the average Joe believes in is false. The whole world knows McDonald's is incredibly unhealthy. If some random study came out saying McDonald's is healthy are you gonna come here and say "oh man the pack mentality must be wrong" because this study goes against the norm? Someone leads a sad life

I don't care about any research - I can clearly notice I feel MUCH more relaxed with warmer screen colors, regardless of the time, day or night.

Exactly, that's why i use this at night especially if I'm gonna be reading... The whole sleep cycle thing was never a problem since I sleep when I'm tired.

Use your devices and screens as you see-fit and in terms of what is lost comfortable for you. Some prefer it on some prefer it off. I can handle both, it all goes by the display I am using.

What researches are missing is that, most people use warmer colors for their eyes. It is a lot more easier on your eyes than blue lights.

Well this study must be ridiculously flawed... Especially since they conducted it on mice. I can stay awake for hours with my screen on and the blue light filter off. The second I turn it on, my eyes immediately (and I'm talking less than a second) relax and feel far less strained and I fall asleep near instantly. I wonder who funded this study. Not to mention Twilight still isn't producing a ton of blue light. It's just a more neutral color tone but is still full spectrum light. Our phones don't produce full spectrum light if you hook up a spectrometer to it. There are spikes around the red, green and blue obviously as there are only Red, Green and blue LEDs/pixels. Blue light is most definitely harmful for the eyes. Just look at laser Safety. Blue lasers ~445nm are far more dangerous for the human eyes at identical power levels than green and red lasers. Ridiculous study right here.
