Sleep Stages comes with Watch OS9


Stages of sleep

Currently, your Apple Watch can only really offer a estimated number of hours of sleep. Now it goes even further to show you precisely how long you’ve slept and how much time you’ve spent in each stage of sleep – awake, REM, core and deep – using data from the accelerometer and sleep sensor. watch heart rate and a bit of machine learning. Apple said it trained its machine learning with polysomnography, the standard method of tracking sleep in clinical sleep studies.

When you wake up, you can see a graph of sleep time and your sleep stages on the Apple Watch. If you want to dive deeper, you’ll also be able to see detailed sleep reports with heart rate and breath rate data in the Health app on iPhone.

Many other wearables, including Fitbits devices, Garmin devices, and the Whoop Band, have tracked your sleep stages for years now. But this will be the first time Apple has done so.

Medication Tracking

The App Store is full of medication reminder and tracking apps, but Apple is about to make them obsolete with its new Medication app, available on both the Apple Watch and iPhone.

In the upcoming app, you will be able to select all the medications you take, both those you take daily and those that are occasional. This includes prescriptions, vitamins and supplements. All you have to do is type in the medications you’re taking or scan a prescription label with the camera. Once your medication list is established, you can log when you take them and schedule reminders so you don’t forget them.

Apple will also let you know if there are any critical interactions, either between your medications or between your medications and other substances, such as alcohol.
