After doing blood drives most people will bother some even experience fainting. Scientists recommend that before blood donors drink lots of water to avoid the risk of fatigue and fainting.
Researchers from the U.S. Red Cross (American Red Cross)
found that drinking half a liter of water or 16 ounces (453 ml) prior to blood donation could reduce the risk of fainting up to 20 percent.
This finding was encouraging because so far people are afraid of donating blood is worried his body limp. With this discovery is expected to more people who voluntarily donate their blood.
“If people fainted after giving blood most will give up and never want to again give blood. If we can reduce the risk of fainting by 20 percent then we can reduce the inconvenience to the donor,” said David Robertson, MD, professor of Neurology at Vanderbilt University as reported redcrossblood.org, Thursday (11/18/2010).
