aisthitrakiphilia is the arousal from sensory deprivation, which is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing respectively, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and 'gravity'.

Some people enjoy sensory deprivation because it allows them to be in a meditative state, others because it is said to enhance your remaining senses, (that it to say, if hearing, sight, and sound are taken away, the sense of touch is heightened.)
