We all know that we need to drink water to stay hydrated and among other things clean our body from toxins.

What comes like a surprise to us when reading this article is that water also makes us more alert for late-night studying, prevent us from fainting after giving blood, and even helps us to lose weight.

Based on these findings American Red Cross made a study on water drinking as a method for reducing fainting responses, when giving blood.

The stunning result of this study shows that drinking 16 ounces (around 500 ml) of water before blood donation reduced the fainting response by 20 percent.

“This response to water may turn out to be very important for retaining blood donors”, Robertson said. “If you pass out after giving blood, you pretty much never give blood again. If we can reduce fainting by 20 percent, we can reduce the unpleasantness of passing out and really bolster the number of people who can continue to be blood donors”.
