but what does it do ?? tells you if you run ? I know when I run .. I know when I sleep and if I've slept well …
I know that I don't sleep well. I can wake up tired (not just sleepy but already tired) even after what seemed to be a fairly solid sleep. I suspect some variant of sleep apnea. I'd like to know more details about what happens during my sleep.
I also have a sleep phase disorder, which I do track in my diary, but a sleep monitor would presumably do that more accurately. I record bedtimes and waking times - and you should see the graph. It's sleep, Jim, but not as we know it. ;o) - but this device would be a boon as it could record the actual sleeping times.
