Regular blood donation is linked to lower blood pressure and a lower risk for heart attacks. “It definitely helps to reduce cardiovascular risk factors,” says DeSimone.
After at least four blood donations, donors with Stage II hypertensive baseline values (≥ 160 mmHg SBP and/or ≥ 100 mmHg DBP) were found to have the most marked reduction in BP, with 17.1 mmHg (95% confidence interval [CI], -23.2 to -11.0; p < 0.0001) and 11.7 mmHg (95% CI, -17.1 to -6.1; p = 0.0006) for SBP and DBP, ...
Sweating, in fact, causes a further decrease in blood pressure because of vasodilatation, with sequestration of the blood in splanchnic organs and stasis in the lower limbs, due to gravity. All this is added to the fall in blood pressure caused by the removal of blood during the donation (450 mL).
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.
The body can detoxify itself naturally (e.g., with help from your liver), but giving blood may help your body's detoxing potential. For example, blood (and plasma) donations have been shown to have an effect on the levels of perfluoroalkyl and polyfluoroalkyl substances (PFASs).
Giving blood is part of a heart-healthy lifestyle and donating on a regular basis has proven health benefits. In fact, studies have shown that donating blood can be good for your heart.
After a donation, most people's haemoglobin levels are back to normal after 6 to 12 weeks. This is why we ask donors to wait for a minimum of 12 weeks between donations (12 weeks for men and 16 weeks for women) to ensure that we don't risk lowering your haemoglobin levels over the long term.
Don't do any heavy lifting or vigorous exercise for the rest of the day. If the needle site starts to bleed, apply pressure and raise your arm straight up for 5-10 minutes or until bleeding stops.
The health benefits of blood donation include lowering your heart rate, your blood pressure, and weight. Some researchers have also found that donating your blood regularly can lower your cholesterol and triglyceride levels. 1 It may seem to be an effective way to lower your lipid levels.
Drinking water can help normalize blood pressure. If you are dehydrated, it can also help lower blood pressure.
However, researchers at the University of California, San Diego have found that you can lose up to 650 calories per pint of blood donated. That's not a bad deal for kicking back and doing a good deed.
Fatigue may occur in anyone who donates blood, especially as the body recovers. A person who regularly works out should not expect to operate at peak performance in the 2 days following blood donation.
In the short term, a minority of donors may experience light-headedness, fatigue, or nausea due to the iron and water loss related to the sudden absence of blood components, but this will quickly pass as stores are replenished.
Slight fatigue is normal after a blood donation, and some people experience this more than others.
That doesn't mean you should chug coffee before giving blood. "It can be a very mild diuretic at times, so that's probably not a good thing," Gottschall said. Caffeine makes you pee, which means less liquid in your body. Donating blood means losing even more liquid.
Your body will replace the blood volume (plasma) within 48 hours. It will take four to eight weeks for your body to completely replace the red blood cells you donated. The average adult has eight to 12 pints of blood.
You can donate as long as you feel well when you come to donate, and your blood pressure is below 180 systolic (first number) and below 100 diastolic (second number) at the time of donation. Medications for high blood pressure do not disqualify you from donating.
At the end of your donation, you will be given fluids to help replace the plasma. Drink plenty of fluids the day of, such as water or juice and have a healthy breakfast. Avoid drinks such as coffee, tea or alcohol as they can dehydrate you.
You must be in good health at the time you donate. You cannot donate if you have a cold, flu, sore throat, cold sore, stomach bug or any other infection. If you have recently had a tattoo or body piercing you cannot donate for 6 months from the date of the procedure.
AB negative is the rarest of the eight main blood types - just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don't struggle to find donors with AB negative blood. However, some blood types are both rare and in demand.
Arteries have high pressure and puncture will lead to lot of blood loss. Arteries carry carbon dioxide-rich blood to all parts of the body from the heart.
Burns Calories – helps lose weight
A single blood donation can help to shed almost 650 calories, which is equivalent to jumping rope for 50 minutes. Each time blood is donated, the body takes this much calorie effort to replenish itself with blood.
Giving blood can help your liver stay healthy
Research has linked too much iron with NAFLD, Hepatitis C and other liver diseases and infections. Though there are many other factors involved in these problems, donating blood can help relieve some of those iron stores and avoid extra issues in your liver.
