Before Blood Donation: Dos And Don’ts

Here are the steps to take before donating blood:

• Get enough sleep the night before you donate to wake up well-rested and energised.
• Eat a well-balanced and healthy meal before blood donation. Avoid eating fatty foods like fries, ice cream, and hamburgers. It’s highly advisable to eat foods loaded with iron, like red meat and spinach, to help your body produce new blood cells after you donate. 
• Drink an additional 16 ounces of water before blood donation as this will help prevent dizziness and fatigue from setting in.
• Make sure that any of the medications you are taking do not prevent you from donating blood. For instance, you shouldn’t take any aspirin for two days before donating platelets. A doctor must be consulted before discontinuing any medication.
• Wear a shirt or top with either half sleeves or full sleeves that can be rolled up for easy extraction of the blood.

After Blood Donation: Dos And Don’ts

Here are the steps to take after donating blood:

• If you feel lightheaded after donating blood, then lie down somewhere and keep your feet up until the feeling passes.
• Don’t remove your bandage and keep it dry for five hours after donating.
• If you experience bleeding once you remove the bandage, then keep your arm raised while putting pressure on the injection site until the bleeding stops. 
• If you experience bruising, then try applying a cold pack periodically for the first 24 hours. 
• Make sure to eat a sugary snack just after donation to avoid getting dizzy due to low glucose levels. Make sure to take an iron-rich diet to replace the lost iron. 
• Stay hydrated as water is one of the major components of blood. Drinking extra fluids helps the body cope with the lost blood. 
• Avoid engaging in intense physical activity or heavy lifting for around five hours after donating blood. This is because manual labour boosts the workload of the body’s circulatory system, which can cause pain, dizziness, and nausea. 
• Avoid drinking alcohol for at least 24 hours as the effects of alcohol are more apparent after donating blood as there would be less blood in your system to dilute the alcohol. Also, blood donation can cause dehydration, which is can get exacerbated by alcohol. 
• Don’t smoke for at least several hours after donating blood as it can cause dizziness. 

Donating blood is a great practice, which can save many lives. Just make sure to follow these tips to make the entire procedure safer and more comfortable for yourself. If you still have doubts,
