Deaths attributed to cold temperatures in the United States have more than doubled in the past 2 decades, with rising cold-related mortality being linked to factors such as homelessness, substance abuse, and social isolation. Researchers found that while mean temperatures are increasing overall, severe winter weather episodes have also become more frequent, leading to an increase in cold-related deaths. The study also highlighted variations in cold-related mortality by population demographics and geographic regions. The findings emphasize the need for public health interventions to protect vulnerable populations by improving access to warming centers and indoor heating.
