Confusing question: As long as it is not unhealthy, why must it have health benefits? The average person replaces 1-2% of their blood daily as it wears out, and can easily increase production 3-4 x, easily permitting blood donation every 8 weeks. Donating is a simple way to give life healing blood to those with greater need.Only healthy donors can provide this material, so donation is a simple way to matter to someone.

Not much: Its good for your spirit. Blood has its own way of replenishing itself. All blood cells have limited life span, after which, the spleen degrades them naturally.

Possible benefit surrounds the opportunity to exchange the body's iron molecules (see "The Iron Elephant," among others, or google "coordination chemistry" for the concept). Just being a hero to three people who you don't know and don't know you should be good!

Usually < 24 hours: Donating blood is a great thing for the community but occassionally one sometimes experience mild side effects from donating. One can experience lightheadedness, dizziness, weakness, and tiredness. These symptoms nearly always resolve within 24 hours, faster if you stay very hydrated and don't skip any meals.

Donating: You will feel a slight high because of the good deed and realizing that someone else will benefit. You will have to replace the volume of fluid removed from your body, and this will equilibrate within 1-2 hours, and you can use any non alcoholic beverage. Remember that people were made with excess blood forming capacity to allow them to bleed a bit from injuries.
