Cold temperatures aggravate health problems like asthma and sickle cell disease. Better data needs to be collected on indoor temperatures in prisons and jails, Weber said, and agencies should have extreme weather plans in place, especially for medically vulnerable people. “It’s truly cold in here, even when the heat works,” said Billy Renshaw, who is incarcerated at Pickaway Correctional Institution in central Ohio. Incarcerated people and advocates reported scarce food and water, interrupted access to medical care and the inability to make phone calls. Antwann Johnson, who is incarcerated at a prison in eastern Missouri, said some people put cardboard in their windows to try to block the cold.
