Sleep time is the time when your body adapts to your hard exercise sessions earlier in the day. You quantify your time-in-zone when exercising why not your time-in-adaptation? Some might argue that adaptation is more important.
You might not do it, I suppose, because the technology is generally pretty inadequate at present.
I saw 3 products at the Excel yesterday that may be able to help: Oura Ring, EMFIT QS and BEDDIT.
They all seemed to have pretty competent apps. Perhaps with BEDDIT losing out slightly. BEDDIT however is apparently sold in Apple stores, so one would assume a degree of competence there behind the product. EMFIT QS is from a longstanding company with a good pedigree and already works with some sports teams as does BEDDIT. Oura is a start up just starting to ship kickstater orders.
BEDDIT and Oura require a Bluetooth smartphone connection. Presumably a good time to simultaneously charge your phone; so that solution could work nicely.
EMFIT has an novel link to your home wifi and a smartphone-friendly web site.
Clearly you wear the ring, but the other two devices go under the mattress (in BEDDIT’s case maybe under the sheet above the mattress – TBC).
EMFIT QS and the Oura Ring work from detailed HRV measurements. To measure lots of stuff – I’ll give a more closer look in the weeks to come.
The Oura ring measure directly from light shone into the skin. Whereas both EMFIT QS and BEDDIT are BCG devices – Balisto cardiograph ie they work by detecting the physical movement your body makes as your heart beats – your entire body vibration. EMFIT’s device is more accurate and able to measure HRV/RR beats.
These ALL seem like GOOD usable sleep solutions – unlike chest straps. If the technology works they are good to go – unlike wrist-based HRMs that cannot provide the necessary accuracy YET.
I would imagine that BEDDIT has links outside to the Apple-world. EMFIT is stated to link to Under Armour and Oura I’m not sure about.
Oura and EMFIT seem to offer much more (breadth/depth/accuracy) than a waking HRV measurement (eg ithelte – like many of us currently use, including me)
