Surely just gentle exercise like walking or even Tai Chi stretching can improve your blood flow?
Just triggered a memory about relaxing places - in the UK Lake District is a nice hotel with a reading area away from the bustle of the bar / reception. Styled like an old study the shape of the corridor seems to insulate all sound within a few yards.
There's a log effect fire that is open to 2 sides if that makes sense and I was hidden away in there reading but sort of zoned out although totally awake.
A log cabin with leather easy chairs for reading and good stereo?
I/m in .
