Experts Outline How Extreme Heat Threatens Incarcerated Populations and Legal Remedies

In a July 2026 webinar, the Marshall Project gathered correctional-health and legal experts to discuss the hidden dangers of extreme temperatures behind bars. Dr. Susi Vassallo stressed that hot weather typically exacerbates pre-existing cardiac, respiratory or diabetic conditions, driving up hospitalizations and fatalities even when heatstroke is not listed as the primary cause. Professor Ufuoma Ovienmhada pointed out that fans often fail to lower heat exposure, especially in humid settings, and many cells lack power outlets, forcing inmates to resort to dangerous self-cooling methods that can trigger disciplinary action.

Staff attorney Rio Scharf highlighted that both heat and cold have prompted civil rights lawsuits invoking the Eighth Amendment, due process clauses, and the Americans with Disabilities Act, though such cases are hard to win. He also mentioned recent litigation over freezing conditions in ICE facilities and allegations of AC being used as a punitive tool. The discussion concluded with practical advice for reporters to mine death records, court filings and grievance reports to uncover temperature-related harms and to consult experts for accurate interpretation.
