Episode Details

This Fourth of July weekend, a deadly heat wave is hitting the central and eastern U.S., with temperatures soaring into the 90s and even hitting 100°F — and humidity could make it feel like 115°F. Extreme heat isn’t just uncomfortable — it’s a silent killer, linked to over 2,300 deaths and 120,000 ER visits last year. Your body may not warn you when overheating, leading to dangerous confusion. Dehydration strains your heart and can cause kidney damage over time. Older adults, kids, pregnant people, those with chronic illness, and outdoor workers are most at risk — especially if on medications that impair cooling. Experts urge you to plan ahead: set up weather alerts, stock up on water, ensure AC or fans work, know where cooling centers are, and check in on vulnerable neighbors. When the heat hits, drink water every hour (even if you’re not thirsty), avoid sugary or alcoholic drinks, stay indoors in air-conditioned spaces, wear light clothing, and avoid outdoor activity during peak heat. If you feel unwell, it could be heat exhaustion — call 911 immediately if it’s heatstroke.
