I'm having trouble reconciling the rest of the article with this:

> If a death occurred either on the 18 hottest or the 18 coldest days that each city experienced in a typical year, they linked it to extreme temperatures. Using a statistical model, the researchers compared the risk of dying on very hot and cold days, and this risk with the risk of dying on temperate days. They found that in Latin American metropolises, nearly 6%—almost 1 million—of all deaths between those years happened on days of extreme heat and cold.

So the 36 most extreme days out of 365 only account for 6% of all deaths? Meaning those days are safer than average?
