Deep sleep trend

I don't think that the measurement of deep sleep vs. light sleep is particularly accurate, it needs to be based on brain activity, not activity of your wrist.

So providing more complex analysis of extremely poor quality data won't help you in your aim. Incidentally, deep sleep and light sleep achieve different things for your body, are you sure you want to mess with the balance?

Well for me the deep sleep vs light sleep is quite consistant, I got around 1.30 to 2.30 hours of deep sleep per night.
I've read that around 45% of the night should be deep sleep (20% deep sleep + 25% REM, vivosmart hr can register the difference). So I should have around 3h to 4h of deep sleep for a 8h night. I am quite below this number, I am 25%. Also I noticed that the more hours of deep sleep the more I fill refreshed in the morning (independently of the total hours of sleep).

I currently changing some habits so a Garmin trend of deep sleep will show my progress or not :p

Garmins deep sleep, consistant or not, is not accurate. Deep sleep is a brain state, and not a movement state measured at the wrist.

Deep sleep also is seperate from REM sleep, with deep sleep occurring earlier in the sleep cycle.

REM and deep sleep are different with different purposes.

REM is good for mental refreshment.
Deep sleep is when the body repairs itself physically.

You can perform a v simple test by strapping on a jawbone up3, or fitbit, or withings snd watch the wildly different numbers. Which one can we trust? According to all the manufacturers, none



Not even garmin wil stand by their sleep stats and the best their stats can show is peaceful sleep and restless sleep. Ie moving a little and moving a lot. In REM sleep you can do both, some people even sleep walk, and this would show up as 'light sleep' @ connect...in deep sleep u are LESS LIKELY to move a lot, but movement isnt the indicator of deep sleep.

You wont be analysing what u think.

Still though, it would be nice to download at least to draw larger comparisons with other data, and if it helps you or u have found a use for it then good for u 👍

Wish they would do something more with the sleep data

I just switched from Fitbit and just starting using the Vivosmart HR plus. I really like it. I was hoping the sleep tracking would also be a bit better than Fitbit, where they just made the sleep data reporting worse.

The movement chart is quite nice. I do think the total sleep time is not important as the deep sleep + light sleep vs awake time. Total sleep is just going to bed until getting out of bed. Every morning I look at all the numbers and do some math in my head to figure out how soundly I have been sleeping and try to correlate that with how I'm feeling that day. It would be great just to have the totals of those sleep numbers vs total time or some kind of efficiency value calculated. Total sleep time is not as important as something like that to me anyway.

heart rate...also

You can see another lack of correlation to sleeping/rest....and your heart rate. Personally I would assume that as you slept...and fell into a solid restful sleep, your heart rate would drop to a daily low during the middle of your sleeping until you wake. However often for me - my heart rate jumps all over the place well above 'resting HR' after the first hour or two of sleep. Research into 'my problem'.... or really lack of, is that after you enter REM or Deep Sleep your heart rate will just do its own thing for much of the night (based on brain activity, dreams, recovery needs....whatever)

Motion during sleeping is very similiar

My sleep is also tracked by my CPAP machine. It gives less detail per time but since it's a prescription medical device, even though it's numbers might be wildly off, its numbers are going to be far better than my VAHR numbers.

My band thinks I am asleep much of the time while watching TV. It appears to start counting my sleep cycle the first time I nod off.

My band thinks I'm asleep much of the time I am on the computer. Given this I'm often amazed it doesn't think I sleep at the office. I do go into hyper-focus mode or "zone" while at the computer so my heart rate goes low. I keep typing though so it should detect movement.

I eventually concluded that the sleep data is for entertainment only. It's poorly correlated with how I feel in the morning. Joint aches, no difference. Muscle aches, no difference. Tossing and turning much worse than normal, it might even say I was in deep sleep longer than average.

I'm on-call and had to work for a bit last night. it didn't think the movement from the bedroom to the home office room and then back again an hour later counted as waking up. Yet it often lists times I get up to take a leak.

I do not need deep sleep.
