Index Sleep Monitor: Accuracy?

I’ve recently started using an Index Sleep Monitor, and the sleep statistics worry me. It seems I’m only getting 30 minutes of REM sleep per night, which is very little.

What do your sleep statistics look like? Could a few people post their stats?

Thanks.

Hi. I have been wearing the ISM pretty much since it was released. What is that? Over a year now? I get trolled for saying I like the ISM, but I do. Here are my REM stats for the past few nights starting with last night.

1hr39m

1hr27m

2hr6m

1hr34min

So yeah, based on my stats, I think your 30min is low. I'd say give the ISM a week or so to adjust to your sleep schedule. I think it takes time for the ISM to determine your baseline.

I’ve changed the way I wear the armband, and it’s better now.

Last night, I had a sleep score of 46% and only 4 minutes of REM sleep. I think the armband was positioned incorrectly (there is a 10-minute gap with no data). Is there a way to delete a night from the statistics?
