Many people don’t like the sight of blood and hate the idea of a nurse with a needle. But the truth is, none of us can live without blood. For many people, just having blood isn’t enough; they need healthy blood that can do the job it is supposed to do.
Who needs to receive blood?
A healthy woman has about 10 pints of blood in her body. A healthy man has about 12 pints. If anything happens to remove some of your blood, it needs to be replaced. Blood is manufactured in the body by the bone marrow. If a small amount of blood is lost or removed for donation, the body is able to replace that blood in a fairly short amount of time. But if you have surgery or are in a serious accident and lose a lot of blood, doctors will need to help your body recover by replacing the lost blood.
The body needs to have the correct amount of blood to make sure all its systems work correctly. If you have too little blood, your body won’t receive all the oxygen it needs and you may become dizzy or pass out. Some people also have diseases such as sickle cell that cause the blood to not work the way it is supposed to. When this happens, they may need transfusions of healthy blood for the rest of their lives.

Donating is easy
It is safe and easy to donate your blood. You can schedule an appointment in advance and the entire process takes just over an hour of your time. All equipment used to draw your blood is new and has been sterilized to protect your health. About half of all donors are male and half are female. All donors must be at least 17 years old and weigh at least 110 pounds. Be sure to take your ID with you when you go to donate.
Donated blood is sent to a lab to be tested to make sure it is healthy and safe for someone else to receive. In most cases, the whole blood is separated into its different components and refrigerated until it is needed. Blood centers across the country supply hospitals and other facilities with blood 24 hours a day, seven days a week.
An average adult has about 10 pints of blood. When you donate blood, the nurse will collect about one pint, which your body will quickly replace. It’s important to help your body recover from this loss of fluid by drinking lots of water before and after you donate to make sure you are well hydrated. Government regulations in the United States allow you to donate whole blood every 56 days. If you are donate just certain components, such as platelets, the waiting time between donations may be reduced.
