Experts are attributing a sharp drop in the number of deaths from alcohol poisoning in Russia to the unseasonably warm winter.

Some 619 people died from alcohol poisoning in January 2020, down 37.3% from January 2019, Russia’s National Center for Alcohol Policy Development said Thursday. The past winter was the warmest since records began in 1891, Russia’s Hydrometeorology Center announced the same day.

Russia’s consumer protection union said the mild winter played a key role in that drop, Interfax reported. Union leader Pavel Shapkin said there is a direct correlation between an increase in temperatures and a decline in alcohol consumption.

“An average 10-degree temperature rise above normal reduces the burden of alcohol on the population’s health by the same 10 degrees,” Shapkin told Interfax.

“As a result, the negative outcomes of alcohol consumption have dramatically decreased,” Shapkin was quoted as saying.
