The Health Dangers of Sleeping on a Hartmann Line

My Great Aunt recently died at the age of 100. Throughout her life she was very much into alternative medicine, and she kept hundreds of newsletters from various alt-health practitioners. Most of them aren't particularly interesting, but while going through her stuff I've found a few oddities, such as a 1990 newsletter warning of the danger of sleeping on Hartmann Lines.

I'd never heard of Hartmann Lines. Wikipedia describes them as "a scientifically unproven grid of invisible energy lines of the Earth's inherent radiation".

But how to know if you're sleeping on a Hartmann line? Well, if you've got a cat and it likes to sleep in your bed, you may be in trouble because apparently cats love sleeping on Hartmann lines. (I'm in trouble!)

I've posted a few snippets from the newsletter below, and also uploaded the full newsletter as a pdf file.

Good thing there are dowsers on the job!

Is this another name for the Ley Lines? I've come across the term but don't know the details.

@Kevin D -- Hartmann lines are a grid, like looking at the longitude and latitude lines on a map. Ley lines run at all angles and start and stop at random. Also: Hartmann lines are a few feet apart while Ley lines are usually many miles apart except where they happen to cross or share a starting point (I want to say Stonehenge has a dozen Ley lines radiating from it, but I defer to anyone who knows better.)

I think Hartmann lines are usually described as electromagnetic / cosmic ray while Ley lines are usually described as 'Earth forces.'

@Phideaux: and both are scientifically described as the alimentary detritus of the male of the common cattle.

Ley lines are more amusingly debunked (someone built a ley line grid of outlets of a famous British chain of stores, the details of which escape me for the moment); but these ones are more trivially idiotic, since basically no bedroom at all could possibly be free of them. Just geometrically, it's obviously bunk.
