Chele - I found an article on the Apple Watch 7's Oxygen Sensor accuracy:
How to use the Blood Oxygen app on your Apple Watch "How accurate is measuring blood oxygen from the wrist? It’s great that Apple is able to offer this piece of data, but is it actually reliable? Well, just like using light-based technology to measure heart rate from the wrist, it’s using a similar method to take blood oxygen measurements. That does bring some similar issues in regards to getting accurate data or data at all. Apple outlines some factors that could impact on getting reliable measurements including having tattoos or experiencing low skin perfusion, which can be caused by being in cold environments. You may struggle to get readings if your heart rate is too high too. Motion and moving your wrist around can affect readings, just as it does on other smartwatches and fitness trackers that measure blood oxygen. It’s likely a reason why Apple and the likes of Fitbit choose to take measurements during sleep where that motion issue is reduced. There’s also reasons why in the medical realms, using a pulse oximeter that sits on your fingertip to non-invasively take measurements is the favoured approach. From that part of the body it’s considered to reduce those potential issues you can experience at the wrist. Dedicated pulse oximeters take a different light based approach to measuring blood oxygen as well, sending two wavelengths of light through body tissue as opposed to the light reflection method used by Apple and others like Garmin, Fitbit and Huawei. Blood also sits closer to the surface skin on the finger making it a better place to take measurements. Apple doesn’t state how accurate it’s blood oxygen sensor is and likely won’t delve into the accuracy discussion unless it starts making it suitable for medical grade measurements like its ECG heart rate sensor." _________________________ Back to the MeetUp bathroom issue. The park does have a YMCA, but it was temporarily closed. No one else seemed concerned about no bathroom. I didn't drink as much water as I would have liked. I started making my own lip and body balms a few years ago. Most of my supplies had expired so I made a simple batch. I'll use a wax (beeswax, cera bellina), and butter (shea, cocoa, ghee), and oils (jojoba, coconut, etc.). I used to make my own perfumes years ago. I even make my own CBD balm. I hate cooking, but for some reason, making balms is fun for me. I really have trouble sticking to recipes. Things usually turn out pretty well anyway. I had a scare the other night. My hip, spine, pelvis and shoulder on the left side starting hurting severely. I do have issues, but not usually that bad all at once. I was worried that I may have fractured another vertebra. (I got a vertebral compression fracture in 2018 from coughing). I have been lifting a lot of heavy boxes and unpacking and arranging things. I lucked out and got an appointment with my primary the next afternoon. I really like her as she treats me like a person, not an annoyance. She sent me for x-rays and I received the results this morning. NO NEW FRACTURE! Again some of it is age-related issues and injuries. I still am having pain. Not as bad though. Well, this was a moby for me!
