8 Facts that will convince you to donate blood regularly

8 Facts that will convince you to donate blood regularly

Donating blood is donating life, hope and future for those who really need it. And better than giving once is becoming a frequent donor. This is because stocks of blood banks need to be constantly supplied to meet both those who are in an emergency (after an accident, for example) and those who need blood bags from time to time (due to long-term treatments and hospitalizations ). The lack of blood bags can lead to cancellations of surgeries and fundamental procedures such as chemotherapy.

Currently, 1.8% of the Brazilian population donates blood regularly; per year, 3.7 million bags are collected. Although these numbers are within the parameters set by the World Health Organization (WHO), which provides 1% to 3% of the donor population, there is still a lot of room for improvement.

Who can and who can not donate blood

You can donate blood to anyone between the ages of 16 and 69 (under the age of 18 need the formal consent of the person responsible, and among the elders the first donation must be made up to age 60), weigh at least 50 kg, not having eaten fatty foods in the three hours prior to donation and having had lunch two hours before) and rested (who has slept for at least 6 hours in the last 24 hours).

Some conditions are temporary impediments to donation: colds and flu, pregnancy, breastfeeding, alcoholic beverage intake within 12 hours prior to donation, tattooing or piercing done in the last 12 months, exams or endoscope procedures performed in the last semester, and behavior and risk for sexually transmitted infections (STDs) in the last 12 months.

Certain criteria definitely prevent donation. There are cases of viral hepatitis after 11 years of clinical or laboratory evidence of diseases transmissible through the blood (hepatitis B and C, AIDS - HIV virus, diseases associated with HTLV I and II viruses and Chagas disease) , of the use of illicit injectable drugs and of having already had malaria (Plasmodium malariae infection, quartana fever).

Reasons to donate blood frequently

Blood donation is 100% voluntary and does not cause harm to your body. What about knowing more about it and becoming a frequent donor today?

1 - A blood donation can save up to 4 lives

After collection, the contents of the pouch are fractionated into blood components (red blood cell concentrate , of platelets and plasma) that are examined so that there is no presence of any disease in them. If there is a serological reaction, the unit is discarded. Otherwise, the components are released and can be used in up to four people, meaning they can save up to four lives.

2 - There is no substitute for blood

Blood can not be produced artificially - so, who need of blood in emergencies or treatments depends solely on donation. There are some synthetic products that can delay a transfusion, but this is a temporary and palliative method, which does not replace human blood.

3 - There is no risk of contracting diseases in blood donation

All material used during blood donation is sterilized and disposable. Thus, there is no risk of contracting a disease during the process.

4 - Your body quickly replenishes donated blood

An adult person, whether male or female, has an average of five liters of blood, and a donation is collected at the maximum 450 ml - that is, less than 10% of the whole blood. This volume is restored within 24 hours by the body.

5 - The donation does not change the density of your blood

There is a popular belief that anyone who donates blood gets "thinner" or "thicker" blood. Pure myth. The cells of the human body last about 120 days; after this phase, are replaced by new ones. In this way, the body understands the donation only as a stimulus to the formation of new blood cells, without thickening or thinning the blood.

6 - Blood donation does not make anyone gain weight or lose weight

This is also pure myth.

7 - You are not exposed if you have blood diseases

Who wants to donate blood goes through a previous evaluation to see if there are conditions or diseases that can be for donation. This interview and these exams are private and the data and results are kept in total secrecy.

8 - Helping others do well for you as well

Both those who receive and those who donate blood benefit. Solidarity is an exchange: psychologically, the feeling of doing good to others positively affects the author of the action.

Spending many hours sitting increases chances of breast cancer

Spending many hours sitting increases chances of breast cancer

In addition to cigarette smoking, family history, and drinking, sitting too much is also a risk factor for developing breast and colon cancer, a joint study by scientists at the American Institute for Cancer Research and Alberta Health Services in Canada. According to the researchers, approximately 100,000 cases of these two types of cancer could be prevented if people with a propensity to develop the disease spent less time sitting.
