New Beddit 3 Sleep Tracker Available at Select Apple Stores Next Week

Wow. You are some cynical folks. Sleep disorders cause a plethora of health issues, including high blood pressure.

It's a low power signal, but I'm trying to eliminate RF wherever possible, especially when it's right by me for extended periods of time.

Made me think of this: https://xkcd.com/radiation/ and also resources like this: http://www.cancer.org/cancer/cancercauses/radiationexposureandcancer/radiofrequency-radiation

Are you trying to limit RF because it might cause cancer? Do you shut down your WiFi and other wireless devices when not needed? I have a relative that was asked to build a house for a lady using all of the latest technologies to keep RF out, protect from electromagnetic fields (EMFs), etc. It was interesting to hear about what all they were doing, but I also couldn't help but think this lady was being taken for a ride because she was willing to pay whatever the cost. :(

I think I'll keep using Sleep Cycle or similar sleep apps and just deduce that my heart was beating while I slept.

This looks like a great product..... except that it communicates w/ the phone via Bluetooth. It's a low power signal, but I'm trying to eliminate RF wherever possible, especially when it's right by me for extended periods of time.

And, as @Defthand said, you folks mocking it maybe need to study up a bit on modern health 101. Sleep (qty and quality) is one of the more important (and overlooked) health factors.

Cancer, or who knows what? Yes, I do turn off wireless stuff when I don't need the signal, and try not to keep it right by me, especially in my ear, for extended periods of time.

Look, I started out in amateur radio back in high school. My original degree was in electronics engineering. I know a thing or two about RF. ;) The problem with those links you sent (and the studies) is that they are operating off like 1950's science.

I'm not worried that Bluetooth is likely to bake my cells or corrupt my DNA (cell signals might, though). However, we now know that genes are more like computers, where the inputs effect the output. cf. epigenetics

I don't know if it's going to cause a problem or not... but neither do the people saying it's safe. What I do know is that RF is almost certainly having some effect at that level. I also know that the strength drops off exponentially, so having a wireless mouse is far different than sticking a transmitter in your ear.

Do what you like. I'm going to try and eliminate risks I don't need to be taking.

A simple calculation in your head can tell you how many hours of sleep you're getting and as to the quality of sleep measurement I'm skeptical that they can do much. If you see your sleep is erratic then what? Surely you're mentally equipped to look at your environmental conditions and block out noise, light, lower temps etc. Without needing an app.

This article is interesting from a sleep doctor's opinion...

Oh, for sure. For most people, they could do *so* much improvement before turning to stuff like this, AND (as I've argued against the 'fitness' stuff on the Apple Watch) it might actually distract people from doing the higher impact fixes.

And, that article makes an important point that most of this sensor stuff is kind of guessing anyway when it comes to what's really going on with us, especially where the mind is concerned. Good points.

But, I'm not sure it has to be an either/or kind of thing. If you're not getting enough sleep, and then it wakes you up 30 minutes early, that's bad. But IF it could properly detect the sleep cycles and you were getting enough sleep, then it could be helpful.

Ironic. People wouldn't need the plethora of sleep tracking apps and devices if their smartphones and tablets weren't keeping them awake at night.
