You beat me to it. Thank you. If people knew how what was going on outside our atmosphere (and some inside), they'd strap cellphones to their heads and groins and call it a day.
Ok, but there is a difference between natural energy and artifically generated energy by humankind.
The cosmos keeps itself in a perfect balance, and we are adapted to it, as a species, due to a long evolutionary selection of the fittest.
We react to an increased sunspot activity as it occurs around every 11 years, and the effect is statistically measurable.
But we are not genetically adapted to dwelling up in the outer layers of out atmosphere, where cosmic radiation hits us harder than under the protective absorbing screen the atmosphere offers for us.
If part of it is missing, as in an ozone hole, rabbits go blind for instance.
If we get an overdose of Roentgen, we get ill.
It 's all measurable how how our bodies react to being exposed.
Of course our sensitivities differ.
Animals, ants withdraw into the earth when rain is coming, they feel a different electrical load in the air.
And sensitive human beings have fine antennas too.
Some people suffer from insomnia, when they sleep close to an electrcial device.
