Those glasses state that they are the only pair that “blocked 100% of harmful blue light in the 400-450 range”

But melanopsin contained in the cells that regulate circadian rhythms have an absorption spectrum extends to slightly beyond 540 nm (see the OP’s post). As the author says, “It’s not sensitive to blue, it’s sensitive to cyan (and blue and green).”

Those glasses probably do what they say in terms of wavelengths they filter, but they are only partially filtering out light relevant for circadian rhythm regulation and sleep.

Did you read the article? He points out “It’s possible that Night Shift does something, but the biggest study I could find of Night Shift mode (still a pretty small study) found little effect on sleep, so if there’s an effect, it must be tiny.” He links the exact type of observational study you asked for

Regardless the maximum possible effect will be constrained by the biology of the cells responsible for responding to blue light. Maybe knowledge of the biology is incomplete or flawed but to not use it to inform what’s possible seems foolish.

So what if it’s a placebo effect? Well some people are spending money and time investing in blue light filtering glasses and other solutions. It’s potentially snake oil and it could keep them from pursuing better solutions that would actually help them sleep

A piercing that takes months to heal and has its own potential side effects (infection for one) does not seem worth weeks of relief after which pain returns. The authors of this study therefore do not recommend this piercing for migraines despite the transitory benefits

“current evidence does not support daith piercing for the treatment of migraine, tension-type headaches, or other headache disorders.”

Memento mori 4 years ago

Yeah but with less regret that your life was wasted on social media and helping twitter and Meta make money

I can relate to the privacy-focused goal of getting away from google however Google Voice is free. Sadly I think having a competing free Google product that accomplishes most of the same things is going to hurt adoption of the Firefox relay product (which is paid)

patient histories are often garbage

This is a little like programmers calling the programming language they invented and write in every day garbage. Separate from patient-reported histories, you medical doctors are the ones documenting these histories and hold the decision making power for how it’s done!

This is a fallacy. At any point in history you can say “if X field was so good, we’d have Y by now”. In 1925 you could’ve said, “if biology’s understanding of bacteria is so good, we’d have antibiotics by now”. Within 5 years, they did.

There is certainly noise in healthcare data especially when patient-reported, but is it noise to say that a patient having X procedure later does or doesn’t have serious complications? Analyzes of medical care and their consequences can be evaluated and it’s not noise

And big healthcare data has lagged, partially because privacy concerns trump sharing. There are companies selling anonymized medical records for basically every American now though. Big data is coming

They have also indicated that getting vaccinated does not reduce your ability to spread the virus

That is not correct. Vaccination does reduce, but does not eliminate, transmission of the virus

“ We found that both the BNT162b2 and ChAdOx1 nCoV-19 vaccines were associated with reduced onward transmission of SARS-CoV-2 from index patients who became infected despite vaccination.”
