Sunlight shining on one side of a cube-shaped liter of flesh would be 10W/kg or so on average (and about 100W/kg if we consider the top 1cm). 1.6W/kg is a conservative limit.
Yeah, but it is important to consider the wavelength. Did our cells evolve to handle constant RF exposure?
This an advertisement for their RF phone cases. In the article the premise is refuted.
> Penumbra was conducting the test, which also included testing an iPhone 7, to study its Alara phone cases, which the company says are designed to reduce RF exposure in a person
I suspect this has something to do with the inferior intel modem that was used during the Qualcomm debacle. One of the main advantages of the next iPhone will be returning to a Qualcomm modem that isn't rubbish.
While I’m not a fan of what apple did it’s a bit disturbing that there’s literally just one company making cellular modems for US devices and that this company is really very hostile to users and device manufacturers.

Placebos work. If that's what you want, cool. If you want to figure out if RF affects sleep, that's cool too, but you'll need to double blind the experiment. Because placebos work.
Yes but so does human intuition and its a heck of a lot faster. A healthy person can endure a toxic environment. An unhealthy person becomes more unhealthy from increased toxicity. I’m not saying electromagnetic radiation makes a healthy person unwell i’m saying it delays or worsens recovery of some unhealthy people and there are million different subsets of unhealthy people so which subset are you going to run the d…
It's also frequently incorrect.

Well you are in the reactive near-field, so the antenna will de-tune, hence the power amplifier won't see it's ideal match, and not deliver as much power. All depends on antenna design and orientation, assuming they don't use active impedance tuning. The base station also tells the phone to back-off. If the TX were running at full power, the battery will die quickly. Leave your phone in a metal, security cubby and yo…
> RF burns are a right of passage for PA designers, and are harmless as it's the outer skin layers. A literal example of skin effect?
Could probably gives non-permanent tattoos with this method.

My ISP supplied router has an option to turn the lights off, which is great as otherwise it illuminates the whole hallway. I don't get why electronics makers think their product needs to have such bright lights.
In a bright environment, a bright LED is useful. Instead they should also have a light sensor used to determine the ambient light level, and then adjust the status LED display accordingly. My Samsung TV does this with its "powered on" light. Of course, that adds to the BOM and manufacturers love shaving off fractions of a penny. Asking them to add an extra 50 cents of parts for something consumers don't think about p…

Old LEDs are fine in both bright and dark environments, too-bright LEDs are a recent (5y? 10y?) thing. I wonder if LCD could be even nicer... I don't think I've ever seen single-pixel LCD status indicator.
I approximate that by using a pin to poke a hole in the electrical or gaffer tape that I use to cover the lights.
1. saying something is impossible is not a scientific statement
2. RF is capable of specifically affecting enzyme reactions, random example: https://pubs.rsc.org/en/content/articlelanding/2014/nr/c4nr0...

Electrosensitivity is denied by intelligent healthy people who have never dealt with unexplainable fatigue relying on statistics and body system diagnosis that is inadequate for explaining chronic complex health conditions. They're all just whinging man. Not one of them ever hoped it was all in their head and they could think their way out of it. Hacker News is a perfect subset of people lacking the perspective to co…
I'm very much in favor of researching electrosensitivity. Whatever the cause, it's undeniable that certain illness patterns are becoming increasingly prevalent. But I'm not really seeing research from electrosensitivity proponents, and especially not double blind studies. Instead, I'm seeing requests for fairly massive accommodations (along the lines of eliminating all Wifi and Cell phone radiation within a certain r…
Once the wifis gone the MCS patients spend more time sitting in front of wired digital display devices activating their central cortexes burning through their constrained glutamate supplies (which is also the most probable reason blind people don’t develop schizophrenia)which depletes their glutathione which increases their pathogenic load and inflammation while their spinal column is degenerating and inflaming from the sitting and those two things have a larger negative effect on them than the positive effect of the reduction in wifi exposure.
The disappointment at their failed remedy further aggravates their condition and nobody is interested in their next bright idea for alleviating their condition. So they live their life out labelled as a whinger and their negative emotions contribute further to their health decline.
They won't recover while exposed to er but because removing er won't cure them this is not a reason for not benefiting from minimising exposure.
Spinal function and glutathione production is as or more important for MCS suffers than a reduction in ER exposure which is important but nobody tells them that and I've no idea how to prove it but at least Im thinking about it while recovering from ME which has more utility than telling them to just get on with it.
The end of back pain book by surgeon Patrick Roth will gradually fix anyone's spinal function with a kettle bell and exercise ball.
Diet and sleep will gradually fix glutathione production.
No one will make money from researching this so Dr's are forced to ask patients to just harden up. There's a lot of benefit in hardening up as well but it won't recover spinal function or increase glutathione production or decrease er or chemical sensitivity.

Some people do believe that non ionizing radiation has effects other than those produced by the added thermal energy (or that the thermal effects are in some way significant). The actual scientific evidence for this is minimal though.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4676010/ Essentially EM fields alternating in the low to medium frequency bands (~100khz-1mhz) can disrupt cell processes by physically jiggling the polar molecules that make up portions of miotic spindles/microtubules. Among presumably other things this effect is being investigated as a cancer fighting mechanism called 'tumor treating fields'. The carrier frequency of mob…
