(Radio Iowa) Many Iowans are caught up in enjoying the last weeks of summer with vacations and yard projects, and giving blood isn’t exactly top of mind. Sue Thesenga, spokeswoman for the American Red Cross, says this summertime lull is causing a critical shortfall in blood supplies and she’s putting out an appeal for donors.

There are multiple locations in Iowa where you can donate blood and Thesenga says it’s easy to find one.

Thesenga says the need is constant, as every two seconds in the United States someone needs blood.
