Sleep Research: Does the blue light of a cell phone really make you sleepy?
Scientists who were fascinated by the study of what artificial light should be the best way to get a good night’s sleep have now rejected the notion that cell phone screens keep people awake.
The scientists at the University of Manchester in the UK say the real problem is not the blue light emitted from mobile phones and other modern devices.
The university team performed experiments on rats and dimmed and turned on the lights to see what effect it had on rats.
According to the controversial study, published in the journal Biology Current Biology, the answer lies in how fast and how bright light is. What was the need for this research?
Each of us has our own time to wake up.
Most people’s body schedules or body clocks are in tune with the surrounding environment, meaning they are alert in daylight and sleepy at night.
But experts have long suspected that artificial light may be interfering with our schedules.
And it is well known that blue light from computer screens and mobile phones has a negative effect on sleep. What did the research reveal?
When the team performed experiments on mice, they not only saw the light sometimes bright and sometimes dim, but sometimes put yellow light on the mice and sometimes blue.
As expected, the team noticed that the bright light, whether it was blue or yellow, did not calm the rats but made them more awake.
But when the light dimmed, it turned out that the blue light was calmer than the yellow light.
Dr. Tim Brown, the team’s leader, says his research has shown that what we see naturally is sleep deprivation.
“The light we receive during the day is a little white or yellow and has a huge effect on our body clock, and the light around us is a little blue after sunset,” said Dr. Tim Brown. Is done.
“So if you don’t want the light to affect your body clock so much, your choice should be dim and blue light.”
In contrast, bright white or yellow light is better for blinking and staying awake.
So what does that mean?
The ‘night mode’ feature in computers and mobile phones dimms the blue light emitted from them and aims to reduce the ill effects of light on your sleep.
According to Dr. Tim Brown, “Nowadays most people change the color of the light on their device and the display, which makes the screen more yellow.
“Our prediction is that the effects of color change are going wrong. And the benefits of changing colors are diminishing the benefits you can reap from dimming your cell phone lights.
There is no doubt that rats stay up all night.
But researchers say the effects of light are the same on all mammals, whether humans or rats. This suggests that the effects of light on mice should be applied to humans as well.
However, the team says more research is needed to confirm these findings.
Commenting on the study, Dr. Manuel Simpson of Oxford University said: “This is a unique study, but we cannot say for sure that it has a similar effect on humans. And that’s the problem with research on animals (that can’t always be applied to humans). “To make sure that, similar research should be done on humans in the future.”
It will now be possible to connect WhatsApp to 4 devices simultaneously without internet
The multi-device feature has been introduced in a new update of the globally popular messaging app WhatsApp.
According to Web Beta Info, a new update of WhatsApp 22.214.171.124 has been released which will make it easy for users to avail this feature even if they are not a beta tester.
What is a multi-device feature?
The multi-device feature allows users to connect WhatsApp to 4 more devices in addition to the basic device. Users who receive this update will be able to use their WhatsApp account on different devices.
WhatsApp had introduced this new multi-device feature on a trial basis in July this year, but now iOS and Android users will also be able to benefit from this feature.
WhatsApp’s new multi-device feature allows connected devices to access WhatsApp even if the phone doesn’t have internet.
So far, users need an internet connection to connect the WhatsApp in their phone to the web and scan the QR code to access the WhatsApp web. The flow of messages also stops.

If you don’t use your phone for 14 days, WhatsApp will stop working on the devices connected to this phone. WhatsApp is now available even without internet.
Millions of users of the popular messaging app WhatsApp around the world are currently in need of an internet connection to take advantage of the app, but now the company has announced the introduction of a key feature in this regard.
WhatsApp has announced that the company will soon be introducing a new feature that will allow users to use WhatsApp on many devices without an internet connection. The multi-device feature is currently in development and will be launched in the next two months for both Android and iOS testers.
