But if you are considering the seasonal differences in daily mortality, I can see why one can argue that winter (or cold-related) mortality is greater.” That was certainly the conclusion of a 2015 epidemiological study of deaths in 13 countries in The Lancet, which found that cold-related deaths in the U.S. were about a factor of fifteen higher than heat-related deaths.
