Power outages, often concurrent with extreme weather, can elevate health risks like gastrointestinal illness, heart attacks, and injuries from fires or carbon monoxide poisoning due to improper generator use. Joan Casey, an epidemiologist, highlights increased hospitalizations and accidents during outages. Vulnerable groups include children, older adults, and those dependent on electricity-powered medical devices. Preparedness steps include keeping battery backups, conserving food and heat, stocking supplies, and maintaining communication through emergency alerts. Emotional well-being is also important during these events.
