The summer’s no vacation for blood banks, and this one has been especially hard: Just after the fourth of July, the American Red Cross issued an emergency call for blood and platelet donations. Justin Kreuter, M.D., Medical Director of the Mayo Clinic Blood Donor Center in Rochester, discussed the need for blood donation and what you need to know before donating blood in a recent article in Health.

According to Dr. Kreuter, this time of year, blood donors are typically out of town and unable to give or they may not be eligible to donate after traveling to certain areas outside the United States. “It really hits us in the summer months,” Dr. Kreuter says. Here's what you should know about pitching in:

  • Eligibility is always changing, and Zika’s a concern this year. According to Dr. Kreuter, "What we’re doing now, per the FDA, is deferring [donors who may have been exposed to Zika] for 28 days, which is twice the known period of infectivity."
  • The FDA regulates donor blood just as aggressively as it regulates drugs. "It takes a lot of money to do the infectious-disease testing that we do [on donor blood], and when we create blood products out of the donation, that’s done to the same standards as any drug manufactured in this country. The FDA holds us to those same standards, so it’s a very high level of quality and also resources that are invested," Dr. Kreuter explains. "These tests and high standards are what’s keeping the blood supply safe, so that if my wife or one of my daughters needs a blood transfusion, I can feel assured that I can just sit at their bedside and hold their hand rather than worry about what that might result [in] for them later down the road."
  • You’ll get a mini-physical before you donate. "We check blood pressure and pulse, we do a pinprick to check red blood cells to make sure they’re safe—we don’t want to make our donors iron deficient," Dr. Kreuter says. He makes no specific suggestions about what you eat and drink prior to donation; just be sure you have breakfast and lunch under your belt, and take it easy on caffeine. "We all live on our daily espressos and whatnot, but we see donors who show up and haven’t eaten [meals] and they’ve only been drinking coffee, and they’re quite dehydrated. When you donate you’re losing circulating fluid, so the water that you drink before and after your donation is important."
  • You’ll hardly feel a thing—seriously. "What we feel [at the start of a blood draw] is just on the surface of our skin. These needles have silicone on them, they’re made to glide and be quite comfortable. After that initial stick, you’re not going to feel anything," Dr. Kreuter says.
  • It’s okay to have a cookie after you donate. "What’s healthy is to keep a balanced diet as you go forward in the day [after your donation]," Dr. Kreuter says. "We tend to stock our canteen area with things like water and juice and then salty snacks, because salt helps you retain a little more of the [water] volume that you’ve lost through donation. The cookies are there because [they’re] something the donor culture has grown up in—maybe not the healthiest option, but certainly an expectation. Believe it or not, I have meetings about cookies. I’ve seen shirts before that say ‘I donate for the cookies.'"
  • Your blood could save patients who haven’t even entered the world yet. "At Mayo, about 15% to 20% of our blood is going to trauma patients and being used in our ER; a lot of our blood gets used supporting patients through life-saving cardiac or cancer surgeries. Cancer patients [also need blood]—chemotherapy knocks down their ability to make their own red blood cells and platelets—and folks who have medical conditions like autoimmune diseases also need transfusions," said Dr. Kreuter. Donations flow to delivery rooms, too: "If anemia is significant enough in utero we transfuse during pregnancy and sometimes immediately after delivery," Dr. Kreuter explains. "A lot of kids need blood in the first couple of minutes of life. Sometimes with newborn babies an emergency platelet transfusion in the first few moments of life is absolutely necessary; in their situation the newborn brain is so delicate and fragile that having these platelets immediately available is the name of the game in order to prevent bleeding into their brains, which results in long-term disabilities."
  • Donating your voice is vital, too. "Hearing about blood donation from a friend or colleague is very motivating in getting [potential first-timers] to think about taking that next step," Dr. Kreuter says. "Our donor population [in Rochester] has an older average age, and we’re trying to reach out to the younger generation to start having the same blood donation habits."
