- The first major heatwave of 2025 began on Friday, June 20, placing over 40 million people across the US under heat alerts.
- Temperatures are expected to reach the 90s Fahrenheit in the Midwest this weekend, with triple-digit highs in major East Coast cities and Denver early next week.
- This extreme heat poses significant health risks, particularly for vulnerable populations, with climate change exacerbating these events.
- The danger is amplified by high humidity and the lack of overnight temperature drops, which prevent the body from recovering.
- Mitigation strategies include using air conditioning, seeking public cooling centers, staying hydrated, and recognizing symptoms of heat illness.
- Workplace protections against extreme heat are inconsistent across the US, with no federal regulations, making it challenging for outdoor workers to stay safe.
