Blood donations are down 10 percent in central Texas. That's not just a number, that's peoples lives who depend on it.
"They say that one blood donation saves three lives so, I mean that always makes you feel better knowing at the end of the day that I've saved three people," blood donor Bob Buro said.
Keith Hitt with Carter BloodCare said this summer's extreme heat is keeping doners indoors.
And now last-minute vacations are keeping them away too.
The need for donations is based on hospital demand and a summer like this where the temperatures are high the need for donations is even higher.
"We have to keep our blood supply at certain levels so we can service our community hospitals so it's an affect all the way across the board," Hitt said.
Another major problem is the temperatures on the donation buses.
The FDA regulates they stay below 77 degrees, so if the air can't pump fast enough, they have to cancel the blood drive.
"We've had to cancel a hand full of blood drives here in central texas due to the heat and our buses not being able to get the temperature down," Hitt said.
But Hitt also said he's confident Central Texans will come through.
"It just makes us all work harder... Central Texans always come up and respond to the needs."
