The cold weather has taken its toll on Green Country.
EMSA crews have treated four men for exposure to the cold or hypothermia this month.
And with the much colder weather blanketing the area, they're expecting more calls.
"It doesn't take long and it doesn't take as cold of temperatures as people think for hypothermia to set it," said EMSA spokesperson Kelli Bruer.
EMSA said there are heating stations set up where folks can go to warm up.
They include: The Salvation Army's Center of Hope, Tulsa County Social Services and the Equality Center on 4th Street and Kenosha.
