Related, back in the 80's I tried a friend's small biofeedback device and learned in a short time how to really relax.

The device was a galvanic skin response device that looked like a mouse.

You put your fingers on it and it would make a tone that would decrease in pitch with less muscle tension. I laid down and tried to decrease the tone and I gradually learned where I was holding tension and how to relax. As the tone got deeper I would get closer and closer to falling asleep.
