Lead author Dr. Antonio Gasparrini, of the London School of Hygiene & Tropical Medicine in the UK, and colleagues reached their findings by analyzing more than 74 million deaths that occurred over 384 locations in 13 countries between 1985 and 2012.
Perhaps the most interesting finding, however, was that cold temperatures were the cause of most of these deaths, accounting for 7.29% of them. Hot temperatures were the cause of only 0.42% of all deaths, meaning cold weather kills around 20 times as many people as hot weather.
Commenting on the overall findings, Dr. Gasparrini says:
“It’s often assumed that extreme weather causes the majority of deaths, with most previous research focusing on the effects of extreme heatwaves.
Our findings, from an analysis of the largest dataset of temperature-related deaths ever collected, show that the majority of these deaths actually happen on moderately hot and cold days, with most deaths caused by moderately cold temperatures.”
