Sensory deprivation

Every now and then I block the blood circulation of the arm resting on the back of the chair.
It becomes "dead" within half an hour.
The feeling is very nice.

Sensory Deprivation for arm? I think it's better for head, like this; I ordered it some months ago and it's fantastic:

Feet and toes torture is also great for "sensory deprivation"
