A new systematic review offers practical evidence for healthcare systems preparing mental health responses to extreme weather events. The analysis of 33 studies confirms three critical findings: mental health interventions reduce PTSD symptoms by 71%, benefits are consistent across multiple disaster types including hurricanes and wildfires, and evidence supports rapid-deployment response protocols.
These outcomes suggest that mental health services should be integrated into standard disaster response frameworks rather than treated as secondary interventions. The consistency of benefits across diverse intervention approaches and populations indicates that evidence-based protocols can be adapted for different healthcare contexts and resource settings.
As climate-related disasters increase in frequency and severity, these findings provide essential guidance for health systems developing surge capacity plans and training protocols for mental health personnel in disaster response.
