Donating blood offers benefits like a free health check (vitals, disease screening), improved heart health (lower blood pressure/risk), better mental well-being (helper's high, pride), reduced risk of certain cancers, stimulated new blood cell production, healthier liver function (iron reduction), potential calorie burn, and aiding people with conditions like hemochromatosis, while ultimately saving lives for accident victims, surgery patients, cancer/disease sufferers, and new mothers.
A healthier heart and vascular system
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.
According to iformation from the Red Cross and the Mayo Clinic, one pint of blood “burns” between 600 and 650 calories. How? Calories are burned when the body expends energy to replace red blood cells that were removed. Of course, blood donation should not be a part of your weight-loss plan.
Another health benefit of donating blood regularly is lowering cholesterol, so it can help you reduce cholesterol levels in the body. By donating blood, the cholesterol in the blood will indirectly decrease along with a long bleeding. It is great for lowering cholesterol.
Many people – especially men – tend to feel better after donating blood. This is likely because your iron level drops a few points when you give blood. It forces your body to produce “new” blood to replace the “old” blood you donated. Some see this as a natural “oil change” for the body.
Hydration is key! You just gave about a pint of blood, so it's important to replenish fluids. For the rest of the day — and especially the next 24 hours — drink plenty of water or other non-caffeinated beverages. Drinks with electrolytes are great choices.
Offers Possible Detox Effects. The body can detoxify itself naturally with help from your liver. Giving blood may help the body's detoxifying potential.
As many donors can tell you, the most common side effect of blood donation is feeling more tired following donation. This is particularly true of whole blood and double red blood cell donations, as they result in temporarily lowered levels of red cells, which carry oxygen in the blood.
Too much cholesterol in the blood can lead to its buildup in the arteries of major organs like the heart and brain. It can take a few weeks to several months to lower cholesterol levels with appropriate treatment. Treatments to lower cholesterol include diet and lifestyle changes, exercise, and medications.
Types O negative and O positive are in high demand. Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population).
When you donate blood, your body works to replenish the lost blood. This process boosts circulation, which is crucial for healthy hair growth. Improved blood flow ensures that hair follicles receive more nutrients and oxygen. This results in stronger and healthier hair.
Regularly donating blood can improve liver health by removing excess iron from the body. The liver's job is to remove toxins from the body, but it can't do this effectively when it has a buildup of oxidized iron. Excess iron can cause cellular damage, which results in liver cirrhosis and other medical issues.
Temporary boost in metabolism – As your body works to replace donated blood cells, it revs up your metabolism. This temporary boost may not last long, but while it does, you may feel more energized and your body may burn calories at a faster rate.
Free radicals are highly reactive molecules that can damage cells and contribute to ageing. Regular blood donation reduces the number of iron stores in the body, lowering oxidative stress levels. This oxidative stress reduction helps slow cellular damage and promotes anti-ageing effects.
# Did you know that people who donate blood are 88% less likely to suffer a heart attack and 33% less likely to acquire any type of cardiovascular disease. # When you donate blood, it removes 225 to 250 milligrams of iron from your body, hence reducing the risk of heart disease.
Bloodletting was once thought to reduce inflammation, boost immunity, and improve circulation by aiding in the detoxification of the blood circulating throughout the body. Over time, however, bloodletting's harmful impacts made the practice a less preferable form of medicine.
To remove cholesterol from your body, adopt a heart-healthy lifestyle by eating more soluble fiber (oats, beans, fruits) and healthy fats (olive oil, fish), exercising regularly (30 mins most days), losing excess weight, quitting smoking, and limiting alcohol, as these changes lower bad LDL cholesterol and raise good HDL cholesterol, with some people needing medication for more severe cases.
High cholesterol often has no symptoms, but when it causes problems, warning signs include chest pain, shortness of breath, numbness or coldness in limbs, unexplained fatigue, dizziness, headaches, leg pain/cramps, yellowish skin deposits (xanthomas), a grey ring around the iris (corneal arcus), and slow-healing sores/ulcers on feet, indicating poor circulation. These signs often point to related conditions like Peripheral Artery Disease (PAD) or heart issues from plaque buildup, but the only sure way to know is a blood test.
Though brewed coffee does not contain actual cholesterol, it does have two natural oils that contain chemical compounds -- cafestol and kahweol -- which can raise cholesterol levels. And studies have shown that older coffee drinkers have higher levels of cholesterol.
Keep the strip bandage on for the next several hours; to avoid a skin rash, clean the area around the bandage with soap and water. Don't do any heavy lifting or vigorous exercise for the rest of the day.
This positive psychological state can foster the release of endorphins and other mood-enhancing neurotransmitters, contributing to reduced stress and anxiety. Thus, by donating blood, you are not only saving lives but supporting your own neurological well-being.
When you give blood you lose red cells and the body needs to make more to replace them. Special cells in the kidneys, called peritubular cells, sense that the level of oxygen in the blood has decreased (due to the loss of red cells) and start secreting a protein called erythropoietin.
Donating blood at least once a year can help improve your blood flow and reduce arterial blockages. Studies dating back to the late 1990s have found that people who donated blood reduced their risk of experiencing a heart attack by 88%.
Donating blood can improve your liver's health by reducing the amount of iron in it. An iron overload in the liver can damage it and lead to severe complications. An excess of iron in the liver can cause diseases such as Hepatitis C, Hepatitis B, and cirrhosis.
The following medications will prevent you from donating blood:
