"Humans require social contact. Over time, the stress of being isolated can cause a range of mental health problems. According to Dr. Sharon Shalev, who authored A Sourcebook on Solitary Confinement in 2008, these problems may include:

anxiety and stress
depression and hopelessness
anger, irritability, and hostility
panic attacks
worsened preexisting mental health issues
hypersensitivity to sounds and smells
problems with attention, concentration, and memory
hallucinations that affect all of the senses
paranoia
poor impulse control
social withdrawal
outbursts of violence
psychosis
fear of death
self-harm or suicide"
