This Is the Deadliest of the 4 Seasons

Winter is a deadlier season than summer, according to a new report that shows twice as many people die of causes related to winter cold than of those related to summer heat.

Of the 2,000 U.S. residents who die each year from weather-related causes, about 63 percent died due to exposure to excessive natural cold and hypothermia, while about 31 percent died due to excessive heat, heat stroke, or sun stroke. The remaining 6 percent died of floods, storms or lightning, according to the survey by the National Center for Health Statistics.

Counties in the highest quartile of household income had the lowest rates of death due to weather-related causes, the report shows, and cold-related mortality increased in the West in less urban counties. Most heat-related deaths occurred in the South and West.

Moreover, the elderly are much more susceptible to weather-related death, with about 40 deaths per million due to cold among people 85 or older, compared with less than one death per million for children aged five to 14.
