It is well known that physical diagnoses and limitations can negatively impact a patient’s mental health.[1] However, it may surprise some that undue anxiety or depression can be the cause behind developing a serious physical health issue.[2] Studies have shown that mental illness when it goes untreated can significantly increase someone’s risk of becoming physically ill.[3] There is little research done on the health effects of incarceration.[4] Nonetheless, some evidence suggests a relationship between incarceration and health.[5] Additionally, during the processes of trial, sentencing, and admission into prison, many prisoners become depressed.[6] Therefore, given the mental toll that is known to effect those in incarceration, that harm extends further into causing and exacerbating physical health issues.[7].

In a 2020 study examining the experiences of solitary confinement, researchers examined the most prevalent physical effects of incarceration.[8] Specifically, the research revealed that solitary confinement exacerbates the effects of chronic illnesses such as obesity, hypertension, and asthma.[9] In this study, inmates who were subjected to solitary confinement experienced “exacerbating musculoskeletal pain.”[10] This creates a cycle of pain causing the inmate to experience physical and mental limitations in a confinement situation where their existence is already severely restricted.[11] The lack of access to activities in solitary confinement leads researchers to question the physical effects of the inmate’s confinement, which are likely not being treated.[12]

Another study further supports the negative impact that incarceration has on the physical health of inmates by tracking of the body mass index (“BMI”) of adult men throughout the course of their lives.[13] The study found that incarceration increases male BMI by causing weight gain in both current inmates and men with prior prison experiences.[14] The conditions in prisons impose major stress on the inmate’s life, which may be the root cause behind the inmate’s weight gain.[15] Additionally, the increase in distress and depression while incarcerated plays a role in obesity risk because of “either increased consumption of energy dense foods or decreased physical activity.”[16] Once again, a vicious cycle is discovered with obesity increasing the risk of depression, and depression increasing the risk of obesity.[17] People who have not interacted with the prison system may think that prison’s controlled food environment, and the required physical activities would cause inmates’ BMIs to decrease.[18] However, this opinion does not take into account the burden that stress places on the body, causing weight gain.[19]

Through countless studies, it has been confirmed that mental health does play a role in negatively effecting physical health.[20] As discussed in this blog post, both exacerbated musculoskeletal plain and unhealthy BMIs caused by obesity, are examples of the physical health consequences of incarceration.[21] Musculoskeletal pain is exasperated in solitary confinement because of the severe mental and physical restrictions those inmates are under.[22] Adult men who are currently incarcerated or have been incarcerated before are developing unhealthy BMI’s due to the stress of prison causing weight gain.[23] These two examples illustrate that incarceration is the causal link between the mental and physical ailments experienced by inmates.[24] So, what does this mean? It is no secret that the discussion to ending mass incarceration generally revolves around wrongful incarceration, harsh sentences for minor offenses, and the fact that over five million people are “under supervision by the criminal legal system.”[25] However, based on the new research discussed above, it appears there is another reason to add to the discussion: the vicious effects that mental health can have on the physical health of an incarcerated individual. Mass incarceration dehumanizes many people across the United States. Treating an inmate’s physical and mental health conditions is one way to protect an individual’s personhood while they are behind bars.
