"warns that sleeping next to your smartphone—the one that emits 3G and 4G signals all night—affects your brain patterns, restructuring your brain cells and likely preventing you from allowing your brain to clean out waste material properly."
Does anyone have any kind of evidence/study of this kind of effects?
- ndonnellan 10y agoIf you read the linked article, they find "...sensitivity to low-level radiation to a subtle degree...". Except they strapped cell phones to users' heads. Given that cell-phone radiation falls off at a factor of 1/r^2, I would imagine the effects disappear very quickly as the cell phone gets further from your head. Also, the 2nd study used 10 sleep-deprived men. That's a pretty small sample size.
- CyberDildonics 10y agoThats what studies do, they use extremes to find clearer evidence.
- XorNot 10y ago10 is pretty small sample size by small sample size standards.
- CyberDildonics 10y agoYes it is, but that has nothing to do with what I said or what I replied to.
- jusssi 10y agoEmits signals all night is quite an exaggeration. Unless the phone is actively transmitting or receiving something, it only checks in with the network every once in a while. I'm not sure about exact times in 3g/4g, but 2g (GSM at least) phones caused audible interference with poorly shielded audio equipment when they were transmitting. I recall an otherwise idle phone only checking in once an hour or so, though the interval was/is probably defined by the network, so that maybe different at different locations. Still, for power saving reasons, I expect an idle phone to just sit quiet most of the time.
- cgriswald 10y agoI'm not certainly most phones are "otherwise idle" given push notifications, apps phoning home, etc. But, most of those devices are probably on wifi when their owners are at their homes asleep in their beds.
- tominous 10y agoPhones turn off wifi whenever they can to save battery life. For example, Apple: "Notifications use Wi-Fi only when a cellular connection is unavailable." [1] [1] https://support.apple.com/HT201925 https://support.apple.com/HT201925
- Johnny555 10y agoI can send a text message to my phone and have it be received within a second or two, so my phone must be connecting with the cellular network at least once a second.
- mysterypie 10y ago> an otherwise idle phone only checking in once an hour or so The phone network has to know which cell tower you're nearby in order to send a call to you. If you're driving, you could get far away from your original cell tower in one hour. If your phone hasn't checked in for an hour and you've traveled a great distance in that hour, how does the phone network know where to send the incoming call for you? I can think of only two solutions: Either your phone checks in much more frequently than once an hour, or the network tries pinging you on wider and wider concentric circles of cell towers in order to locate you. Which is it? (Or something else?)

- yborg 10y agoThat's what your cat is programming you to think while it's on your head all night. You buy the expensive cat food now too, don't you...
- holografix 10y agoHe won't eat the cheap one. His food costs more than the tuna cans I eat.
- xenadu02 10y agoThis sounds like pseudo-science so I'd be extremely wary. Small study making bold claims based on an extremely subtle effect almost always turns out to be statistical noise or a flaw in the study.
