The studies on the effects of electromagnetic fields on the brain are all over the place:

Doctors at the Institute of Social and Preventative Medicine at Bern University used census and mortality data from 4.7 million Swiss to investigate all deaths between the years 2000 and 2005. Using a proportional hazard model, they found that people who lived within 50 meters of high voltage electricity lines were more likely to die from Alzheimer's disease and senile dementia. "Whoever lives within the immediate vicinity of high voltage power lines for more than ten years has a significantly higher risk of developing dementia or Alzheimer's disease," said Matthias Egger, the Institute's head.

And, finally, a 2007 meta-analysis of the studies done on occupational links to Alzheimer’s was conducted by Ana Garcia of the University of Valencia, Spain. She reported that the combined data from 14 different occupational studies showed that, in general, being exposed to EMFs on the job doubled the risk of developing Alzheimer’s...

On the other hand:

The researchers were particularly surprised to discover that months of cell phone exposure actually boosted the memory of non-demented (normal mice) to above-normal levels. They suspect that the main reason for this improvement involves the ability of electromagnetic exposure to increase brain activity, promoting greater blood flow and increased energy metabolism in the brain. “Our study provides evidence that long-term cell phone use is not harmful to brain,” Dr. Cao said. “To the contrary, the electromagnetic waves emitted by cell phones could actually improve normal memory and be an effective therapy against memory impairment”

This might explain the difference:

The additional research is needed to confirm and validate the outcomes of linking Alzheimer’s risk to the environmental and household exposure to the electromagnetic fields with further elaboration on the frequency and magnitude of the levels, dangerous for the health.

Electromagnetic fields cause an influx of calcium which by increasing the formation of peroxynitrite kills brain cells, but by which activating the phosphatidyinositol 3-kinase/Akt pathway leads to the regeneration of brain cells.  Maybe these researchers have figured it out just right or maybe they have just gotten lucky for awhile.

I did read that Joov light was aware of the ElectroMagnetic fields and designed their lights so the EMF would be low, as did... sheesh.. both studies? I can't be sure, and I must go meet my husband and kid at the drop-in centre.

High Voltage centres have those warning do not enter signs for a reason. How close is close proximity? Which occupations were studied? Steel production likely has more power exposure than a.... say pharmacy....

But good scientists and designers do know about this effect and design in order to minimize it. A downed power line from a pole can kill, electricity from a house outlet will shock you, its a series of power step downs. 

Obviously the amount of power flowing through a single device is not as much as in a power station or transformer that is meant to power a small town or section of a city.

There is a difference between the harmful effects of electromagnetic fields when they are the unintended results of incredibly high power, versus when scientists look at what EMF fields do, and develop a theory as to what might help, test it, test it again, test it again, invite other scientists to criticize their work, test some more.

There is definitely some luck in science, but the rest of it is methodical.

Incidentally, red light therapy's discovery could be called lucky, it was a fluke, scientists were using simple red light as a control to measure against.

 But they kept noticing weird results. The control wasn't working. The red light was supposed to do nothing, but it didn't. It was definitely doing something.

Then they decided to look into what the red light was doing and how it was doing it.

This all make infinite good sense.  

In the brain, like in the rest of the body, the same pathways balance cell growth against cell death.  If there is too much stimulus or too much of the wrong stimulus you can get cell growth without cell death (cancer) or cell death without cell growth (neurodegenerative diseases).  The problem in many cancers is that the enzyme (phosphatidylinositol 3-kinase) responsible for cell growth is not de-activated/dephosphorylated whereas in Alzheimer's disease the same enzyme is nitrated/decativated (at least to a considerable degree).  The question for Alzheimer's disease then is how much benefit you can get out of activating that enzyme before it at least partially shuts down.

Here is a good review of the potential effects of certain electromagnetic fields.

https://betweenrockandhardplace.wordpress.com/2017/03/02/brief-report-on-the-alzheimers-disease-cell-phone-radiation-exposures/

Curious is this possible beneficial mechanism of action for cell phones:

...therapeutic effect is elicited through the increased expression of Hsp70 and Hsp90.

And:

In the rostral ventrolateral medulla, the 70-kDa heat shock protein (HSP70), but not HSP90, confers neuroprotection against fatal endotoxemia via augmentation of nitric-oxide synthase I (NOS I)/protein kinase G signaling pathway and inhibition of NOS II/peroxynitrite cascade.

Heat shock protein 70 but not heat shock protein 90 promotes the degradation of protein kinase C alpha which is important since this enzyme is critical to the early onset and progression of Alzheimer's disease through neuroinflammation and nitro-oxidative stress.

Malinow’s team found that when mice are missing the PKC alpha gene, neurons functioned normally, even when amyloid beta was present. Then, when they restored PKC alpha, amyloid beta once again impaired neuronal function. In other words, amyloid beta doesn’t inhibit brain function unless PKC alpha is active.

So maybe early on, there is some there there with this form of electromagnetic stimulation.
