I don’t sleep with my Apple Watch (too bulk) but have been using an Oura ring for years and it does exactly the same thing and it has been spot on always.
 
Similar to afib detection?

I like where apple is going into the health and fitness space.
Where? Don't get me wrong, I use Apple and I like it, but I can't be blind. Apple is in the deep woods when it comes to fitness. Garmin is eons ahead of them. Even Gentler.app is a hell of a lot better than what comes out of the box with the Apple Watch. The rings may have been cool, but they're so 2000 and late now. Adaptive workout prompts and adaptive goals are what I would expect from a trillion dollar company that has more money than Gentler and Garmin. I know I can manually, I know there's a weekly recap and a new goal. If I ran a marathon today because I felt like it, then the next day's goal should be nothing or something like that. Apple's first suggestion should be "rest."
 
Some of this may come down to timing. I got covid last week, likely caught somewhere on a long flight, that night, really sick that night. The next morning, after reading the sleep data, everything but blood oxygen is either elevated, or lack of sleep way down. And, just confirming what I know.
 
Yeah, lack of oximetry really hampers any health app that Apple is promoting at this time. My advice pay the licensing fee. They’re only four years left on Massimo’s patent so pony up the money and let’s go..
I actually haven't heard that it runs out in four years. If so, that's good news for anyone buying AW up to that point. Especially because most don't upgrade so often since AWs don't change so much between cycles. I have the Series 8 and if I buy the Series 14 or so anyway, then it's as if nothing ever happened. Obviously many people's upgrade cycle WILL be affected, but it's better than an indefinite feature axe like I thought until they somehow resolve the dispute.

If there really is only four years left and they stomached almost one already without much consumer backlash after the initial news, it's safe to say they'll save the money and wait it out.
 
My Oura Ring did that already.

Happened to me last month [with Oura]. It told me I had 0.5 ℃ of fever, then 1.1 ℃ the night after. But I was functional, maybe a little tired.

Next thing you know I had COVID. But a very soft one compared to summer 2022.
 
Weird. No data for wrist temp or SpO2 in Vitals on my Ultra 1

I am not sleeping with my Apple watch Ultra as I think it is too bulky for sleeping. I really hope Apple will release a ring at some point as some of the rumors suggests. My wife has the Oura ring as some of the other comments also mentions and that has been working very nicely and have been able to say 'detect' illness before it happens.
 
This is great and all, but Apple Watch still has a lot of work to do in order to truly correctly detect sleep outside of the normal sleep schedule. We are not robots and we have naps at any moment. The watch does not detect them at all. Even if you sleep in late one morning, the sleep detection will stop at the alarm/deactivation of your sleeping schedule. It's ridiculous for a watch that hypes itself so much on this feature in particular. Evidently, the Vitals will be affected by this mess and will give an anomaly/outlier for your sleep.
 
This is an interesting option but when are you supposed to charge your watch? I need it charged and ready to go for the day first thing in the morning.
 
Hi.

Emergency Department Nurse here.

Apple Watch has been great at catching new onset supraventricular tachycardia and new onset atrial fibrillation. It truly has saved lives since atrial fibrillation can cause heart attack and stroke.

Hopefully this new feature doesn’t create a bunch of hypochondriacs. It’s bad enough that people don’t know to take Motrin and/or Tylenol for fever, body aches, and other minor musculoskeletal injuries.
 
I will say it again, the metrics AW collects have been invaluable for me. All I need to do is wear the AW.
I think metrics of metabolic variability are great, and I'm sure they've been well-researched. At the same time, the real red flag in this story is someone who got sick (a cold?) about two times [during the WatchOS beta period]. What was their latest test results for blood levels of Vitamin D? Were they at 60ng/mL, or 20ng/mL? It's great to have the Apple Watch measure vitality, but no device will be able to measure billionths of a gram of Vitamin D in our blood non-invasively. The peril of emphasizing a wearable for preventative health is the things it cannot possibly measure.

"My watch knew I wasn't 100% after my COVID and flu jabs as all three vitals (Wrist Temperature, Heart Rate and Respiratory Rate) were outliers and that's how I knew I was not well, amazing tbh."

Unfortunately, the Apple Watch provides no evidence that differences in wrist temperature, heart rate and respiratory rate are due to the Covid vaccination ... heart rate and respiratory rate are things that are influenced by everything and nothing, 24/7. Unless you have a serious disease, you should rely on your common sense and not on the recordings of a measuring device (Apple Watch).

It seems that an Apple Watch is a wonderful motivator for hypochondriacs. 😂
 
Has there been any news on the blood oxygen sensor support? It seems so odd Apple wouldn't try to appeal this case, or license the patents involved.

I wonder if not enough users have been clamoring for this and the ban hasn't affected sales, so Apple might just be letting it go. Pretty sad if so.
They are still very much still in litigation.

I don’t care about my vitamin D levels, I can get a blood test. But I realized how important AW was recovering from an accident with neck and head injury. Pretty much most of the stuff my neurologist wanted, AW was tracking. This is not a blood test but kind of like early warning, or see the trend of a treatment or over all well being. It’s not a medical device to do invasive procedures.
 
That may be the case, but there’s definitely truth to the fact that your vitals begin changing before the onset of symptoms. How far in advance and to what degree all depend on the person and the illness, but you can’t just completely discredit this, even if the experiences are anecdotal.

Thus me saying "this might work, but..." I'm not discrediting the tech, just the need to have a front page post over two reddit users. When there's actual data or studies, then this is front page.

I'm pretty sure you shouldn't need a device to tell you to take rest after running a marathon. The AW is a smart watch first and tries to be general fintess tracker. I had a whoop for a couple years and it really didn't give that much more insight, then my AW and it whole goal was rest/strain/recovery. I know when I over do it and when I need to push myself.

I charge mine during my morning routine (shower, face, teeth etc) and then in my evening routine before I hit the bed. It's more than enough.

This might work, but right now, this is an article about two users having confirmation bias.

I think the important part of your post is that “this might work,” which is I think the purpose of the article. Whether confirmation bias or not, the valuable information is that it tracks some of your vitals and will let you know when they change.

This is nothing new, the Whoops were detecting covid infections before you knew it. This was published long ago, it's just tracking your data and saying when out of range, apple just cloned whoop.

New or not, it’s great there are now two options to collect vitals, right?

I was surprised at this, as well.

A couple weeks back, my Vitals app showed my overnight / resting heartbeat up from my normal 50 to close to 60, my temperature up 1 degree from normal, etc. I was feeling fine. The next night, same thing, but I woke up with a sore throat and chest congestion - start of a cold.

After the first couple of days of the cold, vitals went back to normal as the cold played itself out (miserably).

As this is the ONLY time I've ever seen the vitals deviate from normal, convinced this is 100% correlated with the illness.

I think you hit the nail on the head for this feature. Maybe not 100% causation, but it gave you a window into your potential future. I think you shared helpful information, now if I receive a warning, I will take proactive steps to ready myself for the potential coming illness. Whether it be stocking up on supplies, planning my calendar, or perhaps trying to help my immune system.

We know, physicians collect your vitals and check whether or not they deviate from “normal” (population wide) when you visit (for nearly any reason). Is it reasonable to conclude that deviation from your average is likely better and more insightful than the general population stats?

You should have a goal to nomally your sleep, the AW can help you with that. You can also set different schedules for different days of the week.
 
Really nice feature and after having a hard round of sickness this fall, turning on the vitals feature, showed that all my vitals were all off and fun to show ones doctor to state something is not normal :)
