“Sleep recording function” appeared on Apple Watch! Good and bad points discovered after using it for a month and a half | Lifehacker Japan

New features were added in watchOS9 and iOS16“sleep stage”. It’s a function that allows you to record the depth of sleep with just the standard healthcare app.

Used for about a month and a half since the OS update in September, pros and cons, third party sleep recording application‌Auto Sleep’I checked the difference between

First, you need to set a sleep schedule.

Until now, I used a third-party sleep recording app “Auto Sleep”, but with this update, iPhone and Apple WatchRecord the depth of sleep even with the standard function onlyIt is now possible.

When you open “Sleep” in the traditional healthcare app, the depth of sleep is4 stages like “sleep phase”is displayed. You can easily check your sleep level.

It is important to note that the recording is only performed if the third party application described later is not used together.Only while “Sleep Focus Mode” is activeThat means. If you say “Sleep steps are not recorded even after updating the OS”, you need to do the following settings.

Step 1

First, set the bedtime and wake-up time from “Normal schedule” to “Sleep” in the Health app on the iPhone, and then turn on “Use schedule for” “sleep” focus mode.

step 2

Moreover, with “Sleep” in the Watch app,“Track your sleep with Apple Watch”Also make sure it is turned on.

At the specific bedtime, it switches to sleep focus mode and the Apple Watch screen goes dark. By wearing Apple Watch in this state and sleeping, you can record your sleep stage.

You can check the depth of sleep and the ratio for each stage

You can check your sleep stage records from your iPhone and Apple Watch. In “Sleep” on Apple Watch, as well as the previous day’s graph,You can see how many hours you slept the previous day and how many hours you slept compared to the previous week.It’s convenient when you want to check how much sleep you got as soon as you wake up in the morning.

For more information, check “Sleep” in the Health app on your iPhone. The depth of sleep is displayed in four stages: “Awake”, “REM”, “Core”, and “Deep”, and the length of time for each stage and the percentage of total sleep are also displayed.

The difficulty is that only using the “sleep schedule”Daytime sleeping cannot be recordedthing If it’s a planned nap, it can be recorded by manually turning on the sleep concentration mode, but it can’t be recorded if it says “Accidentally fell asleep”.

To know if you are sleeping properly, you want to record all the dozing during the day. Not being able to record these automatically is still a little inconvenient.

Daytime recording is also possible by using Auto Sleep etc.

However, if you use a third-party application that supports automatic sleep recording such as “Auto Sleep” or “Pillow”, the sleep stage during the day will also be recorded in the healthcare application in the form of a capture that data.

Moreover, in the case of Auto Sleep, according to the display of the conventional application and the “sleep stage” of the healthcare applicationFunction to change displaywas also added. There is a difference in how to call the depth of sleep between the two, but you can choose a display that is easy for you to understand.

If you change the display to the sleep stage, the daily sleep cycle display will also change to comply with the health care app, such as “REM” and “deep”.

Personally, I found the sleep stages display more intuitive to understand how long each stage of sleep lasted.

Fun for users who haven’t tracked their sleep before

When the Sleep Steps feature was announced at WWDC in June, I thought it might eliminate the need for third-party sleep tracking apps, but the Health app automatically records outside of scheduled hours. As it does not supportIt seems that a dedicated sleep application is needed in the future.

On the other hand, for those who have not used sleep tracking apps before, it might be beneficial to be able to check the depth of sleep with just the standard function.

People who go to bed and wake up at relatively regular times and don’t take napsIf so, you should be able to get a rough idea of ​​your sleep patterns just by setting your sleep schedule. Until now, there are people who have not recorded their sleep for reasons such as “I don’t want to go out of my way to install a dedicated app” or “I don’t want to increase the number of apps I use” perhaps because take advantage of this opportunity.
