Can the Apple Watch record naps?

There is another problem with "Sleep". It is NOT useful, precisely when needed most.

The program assumes someone sleeps like a robot on a regular schedule.

One of the biggest needs is for individuals who have PROBLEMS with sleep. This includes circadian rhythm problems, especially delayed sleep phase syndrome, advanced sleep phase syndrome, free-running sleep phase cycle, shift work disorder. There are people with narcolepsy and idiopathic hypersomnia who cannot maintain regular sleep, cannot sustain sleep but also cannot maintain wakefulness during the day.

It is in precisely those cases where we need an "actigraphy" recording showing the sleep and wake on a diurnal basis, including UNPLANNED or irregular sleep.

HOW CAN THIS BE ACHIEVED WITH THE APPLE WATCH?

I had read that article. I tried again. It does not work. Every time I try to put in a temporary schedule, it insists on modifying the existing schedule for that day. There does not seem to be a way to put in multiple schedules on a single day. There does not seem to be a way to add a temporary, one time schedule. If I try to put in a schedule to start in the next 15 minutes, it schedules it for the next day. Please advise on this. It is not addressed in the article. I have tried on the watch, and the iPhone.

I will try this, but it does not address the problem of people with irregular or unexpected sleep problems. The most extreme example are people with narcolepsy, but there are many milder variants. Sleep pattern monitor is critical for them.
