We're Completely Wrong About Blue Light Filters, Experts Claim

[TKH]

<p style="font-size:18px;">Just got this off a techie website:

<p style="font-size:18px;">Settings that reduce blue light on <a class="" href="https://www.itpro.co.uk/mobile/23617/the-best-smartphones-to-buy">smartphone</a> and <a class="" href="https://www.itpro.co.uk/laptops/23742/best-laptops">laptop</a> displays during later hours could be ineffectual to aiding our sleep, scientists claim, contrary to the widening consensus.


<p style="font-size:18px;">Received wisdom follows that sharp blue light is harmful to health as it disrupts our sleep cycles, with various studies published on the issue, backed by institutions <a class="" href="https://www.health.harvard.edu/staying-healthy/blue-light-has-a-dark-side">such as Harvard Medical School</a>.



D
evice makers have therefore endeavoured to reduce exposure to blue light by developing software that configures displays to show warmer colours at night.
 

<p style="font-size:18px;">However, the opposite may be true, according to <a class="" href="https://www.research.manchester.ac.uk/portal/en/publications/cones-support-alignment-to-an-inconsistent-world-by-supressing-mouse-circadian-responses-to-the-blue-colours-associated-with-twilight(8b6ba562-ade5-4ce9-84db-23cbd0d62904).html">new research</a>, with cooler lights in the evening and bright, warmer lights in the daytime potentially more beneficial to health. This is because the eyes associate warmer and brighter colours with day, and dimmer and cooler colours with night.


<p style="font-size:18px;">Software embedded into devices that reduce blue light settings at night, moreover, <a class="" href="https://www.itpro.co.uk/hardware/34503/apple-iphone-11-review-a-high-octane-crowd-pleaser">like Night Shift in the iPhone 11</a>, are sending our bodies mixed signals, according to University of Manchester researchers. This is because such display tweaks combine a small reduction in brightness with boosting colours that resemble daytime.


<p style="font-size:18px;">“We show the common view that blue light has the strongest effect on the clock is misguided,” <a class="" href="https://www.manchester.ac.uk/discover/news/researchers-discover-when-its-good-to-get-the-blues/">said senior lecturer with the University of Manchester, Dr Tim Brown</a>.


<p style="font-size:18px;">So who do you believe, the USA universities or the British?

Neither. Sadly "researchers" have a terrible record of making incorrect inferences from "data". Hence why anything that is actually important is regulated such as drug research.



How many times have you heard moderate alcohol is good/bad for you? ... unregulated eejits.

Find me any enjoyable human activity, I'll find you a group of doctors against it.

Simple really, if it keeps you awake stop using it. Researchers have to be controversial to keep the funding going.

I remember seeing part of a news special a few years ago where a restaurant had installed blue lighting as the 'experts' had told them the customers would stay awake more and eat and drink more as a consequence.  Sounded like a load o bollox to me.
