I'm not an qualified expert, but I spend a lot of time reading about and using this stuff and I'm extremely skeptical sleep apnea detection is very accurate without the pulse oximeter functionality. But gosh, I hope this is accurate across the Watch's wide user base. I wouldn't say it's likely, but I do wonder if the pulse oximeter is being used surreptitiously. In any case, if you could use the pulse oximeter, this…

I don't think it has to be as accurate as other things like blood glucose levels, because with those people might use the results to inject insulin.

Detecting sleep apnea might be more like afib detection. It just tells someone they should be checked out.

> why I should trust medical advice from a book written before germ theory was widely accepted? Why do you think how to live healthy is a modern invention? Don't you think people had to figure that out ages ago, or else we wouldn't be here?

Because medical science was in its infancy in 1870 and you should only trust medical advice from then if it is obvious, like don't light yourself on fire, or it has been substantiated and backed up with peer reviewed science at some point in the last 150 years. Your argument is just a mix of the appeal to nature fallacy and noble savage trope that people use to justify all sorts of medical treatments with no proven b…

> no proven benefits.

The Romans had great health. Proof: here we are thousands of years later alive and using their letters.

>Undiagnosed sleep apnea affects more than 23.5 million people in the US alone, leading to $150B of wasted medical spend every year. What do they mean by "wasted medical spend" here? (1) Patients incorrectly spending money on a misdiagnosis, or (2) apnea solution providers not making money off people when they could?

(OP here) a third category: downstream complications of sleep apnea, primarily car crashes and heart attacks. Diagnosing and treating people with undiagnosed sleep apnea would prevent these entirely, which is obviously much healthier for the person and reduces medical cost for the entire system (including the patient themselves for co-pays, taxpayers for government costs, etc).

Amazing that you can get much the same functionality in a off brand $30 watch these days - at least monitors sleep and blood oxygen - although it explicitly does not do medical diagnosis. Still every senior should have one for many reasons.

I have extremely severe sleep apnea with 60-100 events per minute, and baseline blood oxygen is low to start with because I live at altitude. I'm very into wearables and have tested most of the top SpO2 capable watches and none of them detect my sleep apnea outside a very rare detection of low O2.

Thanks, I think it would be informative if you put this spelling out in the article. People like myself not immersed in health fields won't immediately know what you mean without it.

IIRC the pulse oximeter isn't all that useful for sleep apnea detection anyway, because on the watch it does not run continuously. Just takes measurements every X minutes. I think the oxygen level drop happens on a short enough timescale that you need the continuous monitoring to pick up on it.

Watch Sp02 detection is usually at rather long intervals to conserve battery and typically have not resulted in any sort of detection of low 02 (in my experience, I have very bad sleep apnea)compared to a pretty dependable and accurate $30 on the finger oximeter.

Sleep apnea is very easily fixed. You have to increase blood pressure on the head by a lot, for a little bit of time each day, half an hour to an hour and it is 100% fixable.

Additionaly increasing blood pressure on the head helps for sleeping more. I do that and sleep for an average of 10 hours a day. 12 hours or 14 hours/day of sleep for me, is not rare either.

Also increasing the blood pressure on the head helps fix myopia 100%, like that woman astronaut who returned to earth and her eyes worked perfectly again.

Raising the foot end of the bed eg with a few thick books under the mattress is supposed to give health benefits by stopping the blood pooling in the lower legs where DVT blood clots most likely occur. Wondering if it also benefits by increasing blood pressure in the head?
