Tracking your health data through wearable devices

Tracking your health data through wearable devices

Experts say devices like smartwatches that continually monitor your health data can also give you early warnings about medical problems before a doctor might. Correspondent David Pogue looks at how self-tracking data may one day help detect conditions like infectious diseases, type II diabetes, heart conditions or even cancer.

    Wow this is sal rich people live that’s great I is this must be California because you don’t see any other homeless people wearing any of these or maybe the government can buy them and give it out to the homeless people in California they do need to wear these things and considering they can’t afford it maybe a couple can supplement it I would agree to pay for this to every homeless person people on food stamps and all those people on social security they’re the ones that can’t afford to eat healthy

    Appreciate the detailed breakdown! Could you help me with something unrelated: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How should I go about transferring them to Binance?

    Do they really want people to visit the doctor more to make billions in doctor visits equals medicine and treatment!!! $$$ it would make sense because the return on people visiting doctors feeds $$$ everyone

    Tip of the iceberg on mass data collection

    Many doctors have created YT videos explaining that Apple Watch’ ECG and AFIB monitoring is useless, while other metrics are more relevant. Doctors also fear that people may rely on their watch to avoid going to the doctor for monitoring because the watch provides false reassurances.

    Can anyone recommend a specific smart watch to monitor the health of an elderly parent?

  7. @chrisfinch8637 on July 21, 2025 at 7:51 pm

    The only Apple Watch I have for the moment, is myself “watching” that I eat Granny Smith “apples”, each and every morning.

    Very soon, I’d like to purchase one of these!

    In March I was feeling not so great, but nothing was wrong. Next day I wake to my Apple watch telling me I had arterial fibrillation over night and my pulse was still elevated. Called 911, Seattle FD medics confirmed this and off to the ER. After some time in ICU, and a shock, I was stabilized. Thank you Apple engineers and future thinking medical researchers.

    You saved my life.

    She lied at 5:24 when she said "absolutely not". Look at her eyes. She was trying to avoid eye to eye contact and was being evasive.

    they’re sexy and good if your health has always been your primary concern

    This is an ad. Be warned

  12. @janetd4862 on July 21, 2025 at 7:56 pm

    If a device could monitor my glucose along with my heart rate, O2 level, etc., I’d be the first in line to buy one! Even if I had to wear a CGM elsewhere on my body that it could “talk” to continuously, I’d still be first in line.

  13. @SlackKeyPaddy on July 21, 2025 at 7:56 pm

    FEAR MONGERING ! Apples watch is going to save y our life, NOT! This is total hype for losers and is just another way to make a commercial.

  14. @ediebaxter6194 on July 21, 2025 at 7:57 pm

    Shame it is not affordable for all people.

  15. @NolaChick82 on July 21, 2025 at 7:58 pm

    I wish they would have talked about FitBit too. Apple obviously paid for this ad.

  16. @2012photograph on July 21, 2025 at 7:59 pm

    What which parties views such sendentives information .

  17. @19battlehill on July 21, 2025 at 7:59 pm

    This is complete surveillance —- DO NOT WEAR THESE SMART WATCHES — they are really bad. Evil masquerading as good.

    They have your health info now but that’s only if you share it.

  20. @andersstengaardjensen2208 on July 21, 2025 at 8:03 pm

    I like to wear a classic watch – I simply fon’t like what smartwatchew look like. Can I wear something other than a smartwatch for healthmonitoring?

  21. @mechan1sm_ on July 21, 2025 at 8:04 pm

    Apple claims that they do not have access to their proprietary watches… What a brilliant lie, no one will really know…

  22. @muhammedshazin9371 on July 21, 2025 at 8:05 pm

    Where’s the galaxy watch

  23. @stevedavid512 on July 21, 2025 at 8:05 pm

    Why am I getting a HR reading on floor and bed as well.. why did Apple do this? Plz reply…

  24. @blomegoog on July 21, 2025 at 8:05 pm

    great concept. bad company. F Apple.

  25. @NHHalKnowsHow on July 21, 2025 at 8:05 pm

    My sleep number bed app said my heartrate was elevated four days prior to any Covid symptoms. I then tested positive when I lost my senses of smell and taste.

  26. @mililaniman on July 21, 2025 at 8:07 pm

    I strive to walk at least 30 minutes a day. I would definitely make good use of an Apple watch.

  27. @jamesg7016 on July 21, 2025 at 8:07 pm

    It’s just a matter of time before this data will be sold and linked to credit scores, insurance premiums, and corporate-owned life insurance plans.

  28. @Zenconstructions on July 21, 2025 at 8:11 pm

    Where are useful and interesting information !!!

  29. @margaretpeabody243 on July 21, 2025 at 8:12 pm

    I guess I’m just old school but I like saving my blood work information from year to year, even requesting it. Paper trails have become shorter and shorter. I want these hard copies securely in my hand not flashing in my face.

  30. @UFRooster on July 21, 2025 at 8:13 pm

    Snyder at 5:30 has lost touch with reality! $50?!? What smart watch that does everything they say is $50? My Apple Watch was $400, I run and use it for music so I can rationalize it. Most Americans won’t use half of what it can do and definitely cannot afford $400+, Michael get a clue sir!

  31. @riza3551 on July 21, 2025 at 8:13 pm

    which model is this ? 3?

  32. @seanspool5152 on July 21, 2025 at 8:14 pm

    I don’t understand the bias with Apple. Samsung has a smart watch. All you hear nowadays is Apple.

  33. @jaymo8206 on July 21, 2025 at 8:16 pm

    I do not trust any of the manufacturers when they claim they do not share, sell or release our private health/medical data to 3rd parties. Apple was busted when they had Siri listening in to private conversations even though Siri was ‘turned off’ BS.

  34. @christinacascadilla4473 on July 21, 2025 at 8:17 pm

    Yeah, health trackers…yeah, I’d really trust Apple. They run sweatshops in China, with Tim Cook justifying that by saying, “We go to China because we can’t find the skills we need anywhere else.” Like someone working in a Chinese sweatshop has some special snap-the-motherboard-into-this-slot skill that can’t be found anywhere else. So I wouldn’t trust that company not to pick up and sell whatever data they can. Once again, David Pouge fails to say, “I’m not a reporter, but I play one on TV.” Where were the interviews with the people (doctors maybe) who might say, “These are all overblown promises so far.” 15 seconds of one person saying they shouldn’t be used in factories, after she was the third person in the segment to say smartwatches are great. This was just an advertisement.

  35. @fracturedfauve on July 21, 2025 at 8:17 pm

    The Apple Watch has been a lifesaver for many people, particularly those with heart conditions. Being able to share with the Dr what the heart is doing is a true blessing.

    It’s also a great fitness tracker. Being able to see activity levels as well as other things is beneficial to overall well being.

    Along with having a watch that acts like a mini smart phone.

  36. @RealMTBAddict on July 21, 2025 at 8:22 pm

    Love my Garmin Instinct. Garmin is the best for training and really diving into your workout stats. Been using a Garmin bike computer since 2012, now have a Garmin 530 and the Instinct syncs my BPM with it.
    Invaluable tool.

  37. @brianw1620 on July 21, 2025 at 8:26 pm

    Apple has done some good things and Apple has done some bad things. Their only real competition for a phone OS is a company that was created to data mine individuals. From a pure business standpoint, Apple saw their differentiator in guarding users’ privacy, and they have ramped up those efforts, to the point that Facebook complained about it. An Apple Watch is not going to spy on you.

    Health trackers! Don’t be fooled by this nonsense! There are mad men who want to turn you into a ‘hackable animal’ So they can track and trace your every move and breath! This piece is simply priming you. Push back!

  40. @alexthompson9516 on July 21, 2025 at 8:39 pm

    They should combine all these apps in a device modeled to look like an old-school Star Trek tricorder.

  41. @sandiegojoey1 on July 21, 2025 at 8:41 pm

    I wonder why they didn’t include the Garmin watch line which is superior to both Apple and Fitbit, however it doesn’t have the AFIB feature so perhaps that’s the difference maker for this interview.

  42. @MrBotchnik7 on July 21, 2025 at 8:43 pm

    So many folks really need a glucose monitoring system. Put your coffers into this feature. You will sell millions more.

  43. @THX-1337 on July 21, 2025 at 8:44 pm

    Okey nice….but gear s still the decently winner UV light sensor to be able to read how dangerous the sun is.
    And yes it happend to me when I was on vacation and took at that time my zenwatch with me instead of my gear S and I turned into a different human being in skin tone 3 days later. And when I came back I wore for weeks at 25 degrees shirts with long arms to keep myself warm in my country
    It are nice applications , even if the quality can be different. But it dont have to be aquarate in perfectness to be able to tell a lot of informstion
    People hate charging tho….like hate it.ive worn it for like 8 years I think…..but my current is a versace versus

  44. @osumjak on July 21, 2025 at 8:44 pm
