@slaw Happy Birthday to your mom Steve.  My Dad came home from the hospital Christmas Eve and is back to causing trouble for everyone...  he’ll turn 91 in a couple of weeks.   
There is quite a bit of information in the literature about the health benefits of the 40 hz tone.   Folks set up tone generators in their basements, some say at just below audible level.  I wonder about timbre since a plain sign wave doesn’t sound particularly salubrious to me.  Further evidence to me, and the real bass players around here can probably say better, is that after a longer session of playing around on my electric bass (I play along to Foghat albums) I can really feel the effect (I think it’s the rich harmonics) in my head as well as the rest of my body.  More study needed.  
Steve based on your prodigious listening marathon sessions , I am not sure you sleep...
