The Health Risks of Extreme Heat

Extreme heat is driving escalating public health risk across Europe, Asia, and parts of the United States, according to a Reuters report. Heatstroke—when core body temperature exceeds 105°F—can rapidly become fatal, contributing to organ failure and death.

Globally, excess heat is linked to nearly 500,000 deaths each year, with a European analysis attributing 68% of 2025 heat-related deaths to climate change–driven warming.

Older adults, infants, people with chronic disease, and outdoor workers remain most vulnerable, underscoring the growing need for targeted alerts and prevention efforts. Read the full article from Reuters here.
