117: I’ve Had Enough With Eight Sleep…

We’ve been using Eight Sleep at the Kummer house for years, and in many ways it’s been an incredible tool. The pod keeps the bed at exactly the right temperature through hot Georgia nights; lets us set different temperatures for falling asleep, the first half of the night, the second half, and waking up; and it tracks sleep, HRV, heart rate, respiratory rate, and even snoring. From a comfort and data perspective, we’ve genuinely loved a lot of what it can do.

This episode isn’t an endorsement, though. It’s about why I’ve grown increasingly frustrated with Eight Sleep’s dependence on constant WiFi and a stable internet connection. 

Here’s the bottom line: if you turn off your home’s WiFi at night – as we do, to avoid unnecessary EMF exposure – the system basically breaks. Cooling stops, you can’t change the temperature, and if the adjustable base is up, you can’t even put it back down. 

But even if you’re not concerned about EMF exposure, the system’s reliance on an internet connection is a major problem. For example, during recent internet and AWS outages, users couldn’t control their beds at all – which is absurd for a product that’s supposed to improve sleep.

Eight Sleep’s response to the AWS outage was to roll out a “backup mode” that lets the app talk to the pod over Bluetooth when cloud systems are down. That might help with outages, but it doesn’t address the underlying issue that a sleep and health company keeps adding more wireless components around your bed. The latest generation even adds speakers and requires more communication between the base and the hub.

We’re in the middle of a move and I’ve decided we’ll rip all of that out and stop using it. I still believe bed cooling is incredibly helpful in a modern, sealed house where airflow is limited, and I’ll keep recommending the idea of bed cooling. But I’d rather use a simpler solution with less EMF exposure, even if that means losing automation, app control, and detailed sleep tracking.

In the episode I talk through that decision, why I can’t comfortably recommend Eight Sleep anymore, and what I’m looking for in a replacement. I also share some lower-tech levers we’re already pulling — like better mattress and sheet materials — and ask you to share what’s worked for you, whether that’s another cooling system, smarter use of windows, or just a more breathable sleep setup.

[00:00:00] MK: If you've been following for a while, you probably know that we've been using eight [00:00:05] sleep here at the Kummer House to improve our sleep. At the end of the day, it's a [00:00:10] mattress cooling, bad cooling solution that helps us regulate our [00:00:15] temperature better at night so we can sleep better and wake up more refreshed.

[00:00:18] Welcome to the Primer [00:00:20] Shift podcast. This is not a, an endorsement for eight sleep or anything on this episode. It's, I wanna [00:00:25] say quite the opposite. Um. But you know, if [00:00:30] you're unfamiliar with eight sleep, it's, again, it's a bad cooling solution. You can set the temperature that you want to have [00:00:35] to fall asleep for the first half of the night, for the second half of the night, and then to wake up and like a vibration [00:00:40] alarm.

[00:00:40] It tracks your sleep and recovery and HRV and heart rate and, and respiratory rate and [00:00:45] all of those things. It can detect, its snoring. So it's really a technologically [00:00:50] advanced solution that has a lot of benefits and we've been. [00:00:55] Loving many aspects of eight sleep for years. We've been using it [00:01:00] again for several, several years, and my wife and I both love [00:01:05] most of it.

[00:01:06] Especially how we sleep. You know, if it's too hot outside or whatever. If the [00:01:10] ACS out doesn't matter because eight sleep is cooling us and keeping us at the exact temperature. There is no [00:01:15] overheating, no uncovering, recovering, et cetera, you know, you know, probably know the deal. If you don't have a bad cooling [00:01:20] system, you're probably used to being too hot or too cold or something in between.

[00:01:24] That [00:01:25] might change throughout the night. Now, one of the things that I absolutely despise of [00:01:30] eight sleep is it's. Inability to function [00:01:35] without an active wifi and internet connection. And I've been [00:01:40] asking eight sleep for years to [00:01:45] make sure the solution functions if I turn off my [00:01:50] wifi at night because, and I've said this in a past several times, the only reason why we have [00:01:55] wifi running at night or on at night is because of eight sleep.

[00:01:59] If you turn [00:02:00] off wifi, the solution stops cooling it. It basically breaks. It doesn't [00:02:05] work anymore. And I find this mind boggling [00:02:10] because Eight Sleep is a sleep fitness company, a health company at the end of the day, [00:02:15] and they completely disregard the potentially downsides of having [00:02:20] you exposed to wifi and electromagnetic fields and radiation [00:02:25] throughout the night unnecessarily.

[00:02:27] Right. [00:02:30] More importantly, you know, if you live in an area where you have your internet connection is su not super stable, and you have a lot of [00:02:35] outages, you know, anytime there is an outage of the internet connection, eight sleep stops working. You know, you cannot control it [00:02:40] anymore. If the alarm goes off.

[00:02:41] If the vibration alarm goes off, you cannot snooze, you cannot turn it off. You cannot [00:02:45] change the temperature. If you use one of the latest eight sleep solutions, it has like a, um, [00:02:50] flexible base that can lift up. So you're like in, in a reading position or lift your legs up if there is [00:02:55] an outage while the thing is up.

[00:02:58] BDLX or your head section, [00:03:00] you cannot even put it back down so you can fall asleep. It's absolutely mind boggling, and they've [00:03:05] been ignoring this for a very, very long time. And then just a couple of days ago, you know, from this recording, [00:03:10] by the time you listen to this might be already be a couple of weeks ago, but there was a huge outage of [00:03:15] Amazon Web Services or AWS, and that affected a lot of [00:03:20] different industries and software platforms and services, et cetera, including.

[00:03:24] [00:03:25] Eight sleep. So the entire eight sleep user base was unable [00:03:30] to control their bed during that outage, which lasted for several hours. I [00:03:35] mean, can you imagine the embarrassment for eight sleep that you couldn't change the [00:03:40] temperature, you couldn't turn it off, you couldn't put your base back down to, you know, [00:03:45] to flat.

[00:03:46] Nothing worked anymore and it's absolutely mind [00:03:50] boggling. And so the other day now. I opened the app store and look at [00:03:55] software updates, and I see that eight sleep released an update. It says, you know, eight sleep continues to [00:04:00] revolutionize how the world sleeps, and now you stay in control. Wow. Now [00:04:05] you stay in control.

[00:04:06] You know, with our latest release, we're introducing our first release of [00:04:10] backup mode and outage proof experience that keeps your pod working even when cloud [00:04:15] systems are down, the app automatically connects to your pod over Bluetooth, letting U adjust [00:04:20] temperature. Turn your pot off. Be a pot on or off.

[00:04:23] Flatten the base and [00:04:25] dismiss alarms without interruption. And once service is restored, your data syncs seamlessly to ensure [00:04:30] autopilot and reports remain accurate. And I'm like, you gotta be [00:04:35] kidding me. You know? So no word about, you know. Well, the only reason why they did this [00:04:40] now is because it was a huge embarrassment that users were unable to use [00:04:45] the software.

[00:04:45] Now here is the thing, though, I haven't tested it yet. [00:04:50] I can only imagine that this backup mode is only [00:04:55] gonna save you if the cloud backend is down. I'm almost [00:05:00] certain that you still need to have wifi, uh, to do anything with it. [00:05:05] Maybe not. Maybe I'm wrong and we'll test it. And later today, you know, you can even have no wifi and no [00:05:10] internet connection.

[00:05:10] Everything works fine. Who knows? But even if that's [00:05:15] the case, which I seriously doubt knowing eight sleep. For me, it's even more [00:05:20] frustrating and angry inducing because they're not doing this because it's the right thing to do from a [00:05:25] health perspective, they're doing that to avoid another embarrassment.

[00:05:28] If one of their [00:05:30] infrastructure components fails again, that they rely on meaning Amazon Web Services. [00:05:35] We have to interrupt this episode for an important message from your feet. They've had [00:05:40] enough of being cramped into traditional shoes. Regular shoes can wreck your back [00:05:45] joints and overall foot health by squeezing your toes and disconnecting you from the ground.

[00:05:49] [00:05:50] That's why I switched to Belu minimalist shoes, and the difference has been incredible. [00:05:55] These shoes give me a perfect natural connection to the ground, whether I'm walking, [00:06:00] sprinting, or lifting heavy, my back pain disappeared. My athletic performance has [00:06:05] improved dramatically, and they're comfortable enough to wear all day.

[00:06:09] Plus [00:06:10] my toes are finally pointing in the direction they're supposed to. Check them out@pva.com and [00:06:15] use code Kummer for 15% off. That's PEL uva.com. [00:06:20] And now back to the episode. And so that has [00:06:25] even confirmed my decision or. [00:06:30] Strengthened my desire, not my desire, because we'll end up doing it to get rid of eight sleep.

[00:06:34] We're [00:06:35] in the process of moving right now. Um, so we are not gonna make any major changes to [00:06:40] our systems right now because we have a lot on our plate. But we'll be [00:06:45] moving in exactly a month as of this recording and eight sleep, even though we have now the eight sleep [00:06:50] Pot four Ultra, which is the, not the latest, latest one because they introduced.

[00:06:54] A [00:06:55] newer version that now has even speakers and the covers to expose you to more [00:07:00] EMFs. And they probably communicate with wifi. So you have wifi around your head, you have wifi under [00:07:05] the mattress because the base needs to communicate with the hub. We'll rip all of [00:07:10] that shit out and will not use it again.

[00:07:14] And [00:07:15] it's really a bummer that a company that makes otherwise [00:07:20] such an incredibly useful. Solution [00:07:25] that can really, really help improve your sleep and the quality of your sleep [00:07:30] and give you insights into how you've been sleeping and how maybe a late [00:07:35] meal or alcohol consumption negatively impact your biometrics and the [00:07:40] quality of your sleep.

[00:07:40] You know, all of that is incredibly useful and we've been. [00:07:45] We've been sleeping better, you know, by having the temperature under your sheets [00:07:50] controlled. It's such, it's just so much easier to sleep. [00:07:55] Better at the end of the day without being too hot or too cold. Now one could argue, well, you [00:08:00] know, if you live out in a, in a, in a, in a, in a hut that is, you know, exposed to the elements all the [00:08:05] time, you wouldn't need all of that.

[00:08:06] And I agree, you know, people have been sleeping without bad [00:08:10] cooling solutions for a very, very long time. And, you know, successively [00:08:15] so. But in our modern world where we live in somewhat tight, you know, [00:08:20] houses where there is no natural airflow, where, you know, we have to rely on AC and you know, all of [00:08:25] those things, to mitigate some of that, a bad cooling solution, like the one from [00:08:30] eight sleep is a really, really viable option.

[00:08:32] And I highly recommend bad cooling generally to [00:08:35] anyone I talk to because it does help, it does improve your sleep, but not, [00:08:40] not if that bad cooling solution at the same time though, exposes you to more [00:08:45] EMFs. Than necessary, especially while you're sleeping and especially in [00:08:50] your bed. That is absolutely ridiculous.

[00:08:52] And so. We'll get rid of eight [00:08:55] sleep, we'll donate it, give it to someone who wants to have it. It's, you know, again, it, it's a [00:09:00] good solution. It's a great solution in many aspects, but I'm looking forward and I'm, you know, I'm not [00:09:05] gonna share too much yet, but we are, we just got, uh, we just found a solution that [00:09:10] can do a lot, that eight sleep can do without the EMF exposure.

[00:09:13] I'll talk about this in the [00:09:15] future because I haven't tested it yet. I can't vouch for it yet. [00:09:20] We'll be switching and if we have to take a step back [00:09:25] technologically from a convenience perspective by not having everything automated and maybe [00:09:30] not having, you know, having the things turn on and off manually at night before going to bed and off in the morning [00:09:35] and, and, and losing sleep tracking, that's perfectly fine.

[00:09:39] [00:09:40] I'd rather sleep on a simpler solution that does not expose me to extra EMFs [00:09:45] than to something that is inherently unreliable. That [00:09:50] requires reliable wifi and reliable internet, even though now there appear to be [00:09:55] mitigating features, the backup mode, uh, that I think a sleep could [00:10:00] have had from the get go.

[00:10:00] There is no need to sync everything up to the cloud immediately. And do you know, [00:10:05] life analysis, um, everything can be done on the device without requiring any [00:10:10] sort of connectivity. Maybe have a schedule, you know, where it automatically turns [00:10:15] wifi on at a certain time and turns it off at a certain time.

[00:10:18] And in between your [00:10:20] sleep is as serene as it can possibly be without any contamination. That's my take. [00:10:25] I obviously love to hear from you if you have found a bad cooling [00:10:30] solution, be it either by, I don't know, opening up the windows at night, in winter or something [00:10:35] else, or a tech technology at the end of the day that's been working for you.

[00:10:39] Or maybe a [00:10:40] special mattress that is, uh, allows for more airflow, uh, fabrics of your sheets. I [00:10:45] mean, we already use, uh, organic cotton. Now we are switching to linen. That that should make a difference [00:10:50] as well. But let me hear it, you know, shoot me an email or leave me a comment. If you're watching this or [00:10:55] listening to this on a platform supporting comment, I'd love to hear from you.

[00:10:58] Um, or on social media. I'm sure there're gonna be [00:11:00] posts, uh, linking to this episode, so let me know there as well. But we'll get rid of eight sleep. [00:11:05] Unfortunately, it's, uh, it's been, it's been a great ride, but it's. It's enough and the [00:11:10] latest, you know, backup mode feature, that they're not only introduced because [00:11:15] of that embarrassment, that was the a WAS outage, um, that just [00:11:20] pushed me over the edge and I can't really recommend that anymore, and I don't [00:11:25] want to.

[00:11:25] So. We don't wrap it up. Um, different episode for, for a [00:11:30] change. You know, usually I have only good things to say about the topics that I talk about today. Not so much, [00:11:35] but it has to be said. You know, I, I, I wanna, I feel like I wanna share, you know, what I, what I think I wanna share [00:11:40] my opinion mostly. Good. I usually talk only about things that I really like and, uh, [00:11:45] avoid comments of stuff that I don't like because there's a lot that I don't like.

[00:11:48] But in this particular case where we've been [00:11:50] using this for so long, where we've been recommending it for a while, I feel like, you know, I. [00:11:55] I changed my opinion on night's sleep and it is what it is unfortunately. And [00:12:00] with that, we gonna wrap it up and I hope I'll see and hear you in the next [00:12:05] [00:12:10] episode.
