Health professionals give the guideline to avoid exercise after giving blood for 24 hours, and to avoid heavy exercise such as marathons or triathlons for at least 2 weeks. If you've got a marathon or a big weight lifting comp coming up, then it's probably not a good idea to donate anytime soon.
High-intensity exercise after donation can cause fainting and may increase the risk of excessive bleeding from the area where the needle enters your skin. We highly suggest drinking a lot of fluids and waiting 24 hours after your blood donation to perform physically-strenuous activities.
Healthy people can donate platelets every 2-4 weeks, as platelets are replaced within a few days of each donation. There is a lower risk of iron depletion because the red cells are returned. Regular blood tests are taken to check your platelet count is adequate.
Meats, fish, nuts and peanuts are common protein-packed foods rich in iron. In addition, foods such as raisins, beans, whole grains, rice flakes and watermelon can help restore your body's iron to keep you healthy.
Don't go for a hard run before you donate, the blood service asks us to avoid strenuous exercise beforehand. Even if you feel fine don't go for a run just after giving blood. It's best to wait 24 hours. Bear in mind you won't get your best performance within two or three weeks of donation.

After donating blood, it's likely you'll experience some physical weakness, especially in the arm into which the needle was injected. For that reason, the nurses will advise you to avoid intense physical activity or heavy lifting for five hours after you donate blood.
REPLENISH BLOOD
When you donate blood, your body replaces the blood volume within 48 hours of donation, and all of the red blood cells you lose during donation are completely replaced within four to eight weeks. This process of replenishment can help your body stay healthy and work more efficiently and productively.After donating blood, it's likely you'll experience some physical weakness, especially in the arm into which the needle was injected. For that reason, the nurses will advise you to avoid intense physical activity or heavy lifting for five hours after you donate blood.
Your haemoglobin levels. Before every blood donation we always test your haemoglobin levels. This is because any iron deficiency can result in reduced haemoglobin levels, and eventually, if not treated, in iron deficiency anaemia. This deficiency can make you feel tired.
Side effects of donating blood
Some people may feel nauseous, lightheaded, or dizzy after donating blood. If this happens, it should only last a few minutes. You can lie down with your feet up at the until you feel better. You may also experience some bleeding at the site of the needle.After your blood donation:
- Drink extra fluids for the next day or two.
- Avoid strenuous physical activity or heavy lifting for the next five hours.
- If you feel lightheaded, lie down with your feet up until the feeling passes.
- Keep the bandage on your arm and dry for five hours.
Donated blood is separated into red blood cells, platelets and plasma, and each has different storage needs. "Blood that's donated, we can keep the red blood cells for 42 days. For platelets, we can keep them for five days. For plasma, we can keep it for a full year."
When blood loss nears 30 to 40 percent of total blood volume, your body will have a traumatic reaction. Your blood pressure will drop down even further, and your heart rate will further increase. You may show signs of obvious confusion or disorientation. Your breathing will be more rapid and shallow.
If You Feel Faint While Giving Blood. During a full blood donation, a person gives 450 ml of blood. Infrequently (e.g. 1 percent of donations at our Blood Centre) the donor may experience side reactions during or after the donation: weakness, dizziness, cold sweat, fainting and other symptoms).
Feeling unwell after giving blood? If you feel faint (light headed or dizzy, hot, sweating, trembling, shaky or nauseous) lie down immediately, rest until you feel better and drink plenty of fluid. Any bruising is usually harmless and will disappear over time.

No, blood donation won't become a weight loss fad any time soon. However, researchers at the University of California, San Diego have found that you can lose up to 650 calories per pint of blood donated.
However, in the United States, AB-negative is considered to be the rarest blood type, and O-positive the most common. The Stanford School of Medicine Blood Center ranks blood types in the United States from rarest to most common as follows: AB-negative (.
Platelets in the bloodstream live approximately 8 to 10 days and are rapidly replenished. When levels are low, they most often return to normal in around 28 to 35 days (unless another chemotherapy infusion is received), but may take up to 60 days to reach pre-treatment levels.
The average healthy adult produces anywhere from 400 to 2,000 milliliters a day. Or on average, 34,400 liters in a lifetime.
After giving blood, it is important to follow the post-donation guidelines including to avoid drinking for at least 12 hours following your donation. Alcohol dilates the blood vessels, which causes less blood to be available to circulate to the brain.
That's because there's less water in your blood to dilute the alcohol. As a result, the amount of booze in your blood is more concentrated, so it packs a greater punch.
