Extreme weather is a big deal, but people often overlook the dangers of cold weather. Many think heat is the main problem, but research shows that cold weather is actually more deadly. Over the past 25 years, cold weather has caused 65% of temperature-related deaths in the U. S. , while heat caused 35%. This means that out of 69, 256 deaths linked to extreme temperatures, most were due to cold.

The study, published in the Annals of Internal Medicine, highlights that these deaths are preventable. Older adults, men, and non-Hispanic Black individuals are at the highest risk. This pattern has stayed the same for 25 years, showing that certain groups need more protection.

Most studies focus on either heat or cold separately, but this study looked at both together. It used real data from the U. S. over 25 years, giving a clearer picture of who is most affected. The findings show that cold weather can worsen chronic conditions like heart disease and respiratory illness, often without extreme cold events.

Cold-related deaths often happen indoors in poorly heated homes, especially among older adults. Improving housing insulation and ensuring access to heat can save lives. The National Weather Service reports more heat-related deaths, but this is because they only count deaths tied to specific weather events. Death certificates, which include chronic and indirect effects, show more cold-related deaths.

The study also found that the gaps in risk are not just environmental but also an equity issue. Older adults, men, and non-Hispanic Black individuals face the highest risks. These disparities have been consistent over time, highlighting the need for targeted protections.
