During the busy travel season, which runs from Thanksgiving through New Year's Day, the need for blood donors increases, but this is often a catch 22; more blood is needed, but donors are away from home.
"A lot of people are not donating as they normally do because they are out for the holidays and spending time with their families and traveling," says Nancy Breckenridge from United Blood Services.
More people traveling almost always means more accidents, and it only takes one serious injury requiring major surgery to deplete the blood supply.
"We need blood more this time of year because there are more accidents. People are out hunting this time of year and traveling more, so a lot of times the need for it is greater because of this."
Rush Hospital held a blood drive for its employees. There are many reasons to give, but we let a Regina McPherson, who was donating blood, explain.
"If you are able, come give blood. You never know, you might be in a car accident. You might need blood. They may not have your type of blood. Just be prepared. Come out and give blood to people that need it. "
Those with type O negative are strongly encouraged to donate. O negative is often referred to as the universal blood type and is used in emergencies.
