Why one should donate Blood?

I am one of the active member of the Red cross Team in Orissa.For me there has to be every reason of one doing an activity. There has to be pros and cons of that particular activity. So I did research on WHY ONE SHOULD DONATE BLOOD?.There are numerous reasons on why one should?Here are some of them:- 1.No doubt the first and foremost advantage of donating blood is the exalted feeling of saving some one's life. If we donate the little excess blood in our body, it could save some one's life without creating any problem for us. Instead it would help to alleviate some major health problems like heart diseases. 2.Blood donation is an excellent way to get rid of excess iron accumulated in our body due to its over consumption. Excess iron in the body can stimulate the formation of free radicals, which are responsible for causing damage to body cells and tissues. Free radicals are also associated with many diseases like heart diseases and cancer. 3.Besides, blood donation also burns the extra calories and reduces your cholesterol level. After donating blood, the count of blood cells decreases in our body, which stimulates the bone marrow to produce new red blood cells in order to replenish the loss. 4.A Red Cross Donor is given a Blood donor Card. With this card, the donor will be given priority in case of blood needs. There are no major disadvantages of donating blood, except that sometimes one may experience a drop in blood pressure due to hypovolemia (a state of reduced blood volume), which may necessitate cancellation of donation. Sometimes, one may also experience mild nausea or dizziness for a short while But if you compare the health benefits and mental satisfaction that comes from saving a life, you will feel that benefits of this act of charity is not only restricted to the recipient, but also helps the donor immensely.
