About The Study: Cold-related mortality rates more than doubled in the U.S. between 1999 and 2022. Prior research suggests that cold temperatures account for most temperature-related mortality. This study identified an increase in such deaths over the past 6 years. The underlying drivers of this trend warrant further research and may include more frequent extreme winter weather events and/or the rising burden of risk factors for cold-related mortality such as homelessness, social isolation, and substance use.
