Hey, it's Ben Greenfield. And you know what time it is. Well, you always know when you see the red lights and me in my bedroom. It's creepy time video. That's right. Actually, no, in all seriousness, I'm in my bedroom where I do all my sleep hacking, and I've got this SR1 device that I talked about recently. It's the pulsed electromagnetic field device. I wrote an article about it. You could read about it@bengreenfieldfitness.com Deltasleeper Deltasleeper. But anyways, I've gotten a lot of questions about where you put this thing, this device. You don't want to put a device in the wrong place, especially when you're in the bedroom.
Anyways, though. So it's designed to be worn over the brachial plexus. Your brachial plexus is, like, right about there, a very important nerve complex that feeds up into your brain. That's how this thing actually works. So what I do is I've got my adhesive on the backside of the Delta Sleeper, and I can turn it and basically place it right over that brachial plexus. One thing that you can do is you can find your sternum right here and just draw a line over from your sternum till you get almost over to your collarbone. There's usually, like, kind of a pit here between your humerus and your collarbone. You. You want it right around in that area, and you'll just press it down. And you'll notice if I press the button here, hold it down. I'm not sure if you can see that green light came on. So it's going to stay on for 22 minutes and lull me into deep delta sleep. So that's how it works. I hope you enjoyed that creepy, creepy video.
