After providing background on the widespread use of solitary confinement in the United States today, the statement includes a concise and well-documented section titled “Harmful Effects of Solitary Confinement.” (See the original for citation of sources):
There is a broad consensus among mental health experts that long-term solitary confinement is psychologically harmful. Indeed, the damaging effects of solitary confinement, even on persons with no prior history of mental illness, have long been well known. Over a century ago, the United States Supreme Court described the effect of solitary confinement as practiced in the nation’s early days:
A considerable number of the prisoners fell, after even a short confinement, into a semi-fatuous condition, from which it was next to impossible to arouse them, and others became violently insane; others still, committed suicide; while those who stood the ordeal better were generally not reformed, and in most cases did not recover sufficient mental activity to be of any subsequent service to the community.
In 2002, a California prison psychiatrist told Human Rights Watch:
Prisoners exhibit a variety of negative physiological and psychological reactions to solitary confinement, including: (1) hypersensitivity to external stimuli; (2) perceptual distortions and hallucinations; (3) increased anxiety and nervousness; (4) revenge fantasies, rage, and irrational anger; (5) fears of persecution; (6) lack of impulse control; (7) claustrophobia; (8) severe and chronic depression; (9) appetite loss and weight loss; (10) heart palpitations; (11) withdrawal; (12) blunting of affect and apathy; (13) talking to oneself; (14) headaches; (15) problems sleeping; (16) confusing thought processes; (17) nightmares; (18) dizziness; (19) self-mutilation; and (20) lower levels of brain function, including a decline in EEG activity. EEG changes were observed after only seven days of solitary confinement. In a 2005 submission to the United States Supreme Court, a group of psychologists and psychiatrists concluded that
The statement, which should be read in full, also contains sections on “Solitary Confinement and the Mentally Ill” and “Solitary Confinement and Physical Abuse.” It ends by laying out a set of principles for limiting and monitoring the use of solitary confinement, and asks the HRC to “call on the United States to adopt policies and practices for the use of solitary confinement consistent with the following principles”:
Solitary confinement should be used only in very exceptional cases, for as short a time as possible and only as a last resort.
Segregation of prisoners for their own protection should take place in the least restrictive setting possible.
Decrease extreme isolation by allowing for in-cell programming, supervised out-of-cell exercise, face-to-face interaction with staff, and access to television, radio, telephone calls, correspondence, and reading material.
Decrease sensory deprivation by limiting the use of auditory isolation, deprivation of light and reasonable darkness, and punitive diets.
Allow prisoners to gradually earn more privileges and be subjected to fewer restrictions, even if they continue to require physical separation from others.
Prohibit solitary confinement of prisoners with mental illness, children under age 18, and death row and life-sentenced prisoners by virtue of their sentence.
Prohibit the intentional use of solitary confinement to apply psychological pressure to prisoners.
Carefully monitor prisoners in solitary confinement for signs of mental illness and promptly remove them from solitary confinement if such signs appear.
Invite United Nations special rapporteur on torture to conduct a fact finding mission and facilitate access to prisons and inmates victims of prolonged solitary confinement.
