The June Red campaign emerged in Brazil to draw the population's attention to blood donations, especially at this time of year, which, as it is colder, usually results in a drop in the number of donations.

Blood donation is essential for us to maintain global health, and it is fundamental for saving lives. In several procedures, especially surgeries, blood plays a fundamental role and is considered irreplaceable. As it is a completely voluntary act, it is necessary to make the population aware that, without donations, there is no blood bank.

Another reason why the month of June was chosen was the fact that in this same month, more precisely on the 14th, we also commemorate World Blood Donor's Day.

Before we continue, we need to know: do you already use medical software to perform your appointments at your clinic? We invite you to discover Ninsaúde Apolo, an online software that can be used on a tablet, smartphone, or in the traditional way, on computers. Learn more at our website.

The process for donating blood starts even before the act since there are not only many health issues but also many health surveillance rules to limit the possibility of donating contaminated blood, which can even happen because of the immunological window.

Besides being in good health, it is important to be fed. However, it is important to avoid fatty foods in the 3 hours before blood donation, and if you donate after lunch, you must wait at least 2 hours.  In addition, it is also necessary that the donor has slept at least 6 hours in the last 24 hours, and there should be no alcohol intake in the 12 hours before donation.

When donating blood, some possible impediments are observed, which can be temporary or permanent. It is necessary to meet some basic requirements, such as being between 16 and 69 years old (provided that the first donation was made up to 60 years of age) and weighing at least 50Kg. You must have a document with a photo to prove your identity, and minors under 18 years of age can only donate with formal consent from those responsible.

Post-donation care

After donating blood, it is important to take some precautions, and it is recommended to remain at the collection site for another 15 minutes to avoid feeling bad about the donation. The donor must continue to feel well during the day the blood donation is made.

In the 12 hours after the donation, avoid exaggerated physical exertion, and under no circumstances should you work on scaffolding or practice extreme sports such as skydiving or diving.

In the period after the donation, have a small snack and hydrate yourself. To do this, increase your water intake. If you are a smoker, avoid smoking for at least 2 hours after collection and avoid alcoholic beverages for at least 12 hours. Also, keep your bandage on for at least 4 hours.
