SomniResonance SR1
In my search for devices that can actually help with sleep, I ordered a SomniResonance SR1 (sometimes referred to as a “Delta Sleeper”:
I’ve know about this device for 7 or 8 years. I originally heard about it via Ben Greenfield. He has a number of posts on it.
Background
The device uses low intensity PEMF targeted to your vagal nerve (which signals back to your brain).
When I first became aware of it, it sold for about $500; now $199.
Using the device requires double sided adhesive strips, which the company sells in packs of 30 for $8.50, so one does have an ongoing cost. They send a pack of 30 with the purchase of the device.
Returns possible within 30 days, but it has a $50 “restocking” fee.
One places the device just below the collar bone (either side) close to the hollow between the pectoral muscle and the deltoid.
Some users place it their foreheads.
The device has a single button, no other controls, no connection to an app.
It does one thing.
Pressing the button starts a 22 minute session which the maker claims stimulates delta waves in your brain which enable you to fall asleep faster.
If you wake in the night you can press the button again for another 22 minute session.
You can also use it for naps.
Experience
I’ve used it over 4 nights.
I’ve done as many of 3 sessions in a night.
Small. Easy to wear. Doesn’t interfere with back or side sleeping positions.
Over the first 3 nights, my sleep seemed to improve but not too much.
Night four I had the best (as measured by my Oura ring) night’s sleep I’ve had to 2 months.
Quicker to fall asleep.
Quicker to fall back to sleep.
Far shorter periods awake during the night.
More deep sleep.
More REM sleep.
More sleep.
Early day’s. I report back in a week or so.
