text: White torture, often referred to as white room torture, is a type of psychological torture technique aimed at complete sensory deprivation and isolation. A prisoner is held in a cell that deprives them of all senses and identity. It is particularly used in Iran; however, there is also evidence of its use by Venezuelan and United States intelligence services.
  Methodology
  Visually, the prisoner is deprived of all colour. Their cell is completely white: the walls, floor and ceiling, as well as their clothes and food. Neon tubes are positioned above the occupant in such a way that no shadows appear.
  Auditorily, the cell is soundproof, and void of any sound, voices or social interaction. Guards stand in silence, wearing padded shoes to avoid making any noise. Prisoners cannot hear anything but themselves.
  In terms of taste and smell, the prisoner is fed white food—classically, unseasoned rice—to deprive them of these senses. Further, all surfaces are smooth, robbing them of the variability of touch sensations.
