“The consequences of these heat waves can be severe. A Columbia Law School climate study estimated that most of those incarcerated did not have air conditioning in their units. Exposure to high heat alone can lead to increases in aggression, suicide, poor cognitive functioning, and overall poor mental health. What’s more, over 20 percent of people incarcerated in U.S. prisons have a mental illness, and an aging prison population means that many individuals are suffering from medical conditions like high blood pressure. Psychotropic drugs and high blood pressure medications can both disrupt the body's ability to regulate heat and cool itself down—meaning that many people in prison face higher risk of overheating.“
