When you donate a pint of blood it takes around 24 to 48 hours for the body to replace that pint of blood.

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.

When you donate blood the amount of blood that is taken from your body for blood donation is 0.5 L of blood.

For a whole blood donation, approximately 0.5 L of blood is collected.

For donations of other blood products, such as platelet or plasma, the amount collected depends on your height, weight and platelet count.

Things you should not do before giving blood are eating fatty foods, including hamburger, fries or ice cream.

You should also avoid coffee or other caffeine based drinks.

Drink plenty of water before the blood donation.

Check to see if any medications you are taking or recently took would prevent you from donating.

For example, if you are a platelet donor, you must not take aspirin for two days prior to donating.

You can donate blood even if you have a tattoo as long as the tattoo was done by a certified tattoo artist.

There is a rule though: you have to wait four months from the date of your tattoo or piercing before donating blood.

And if you give blood between four months to a year after having a tattoo or piercing, staff at the donation center might have a few extra safety checks to do.

When you have high blood pressure you cannot donate blood while the blood pressure is high because it can affect your health and the blood may flow to fast out of your body as well.

Once your blood pressure has decreased though then you can donate blood.

Acceptable blood pressure rate for blood donation is below 180 systolic (first number) and below 100 diastolic (second number) at the time of donation.

Even though, the donor is on regular medications, one must understand that medications for high blood pressure do not disqualify you from donating blood.

Provided, you don’t have side effects related to your medication.

Also, the person shouldn’t be suffering from other co-morbid diseases associated with hypertension.

People who have fluctuating blood pressure with irregular treatment must stay away from donating.

As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you're over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.

The stroke level for high blood pressure is any blood pressure reading above 180/120 mmHg.

Blood pressure readings above 180/120 mmHg are considered stroke-level, dangerously high and require immediate medical attention.

Aspirin can help lower blood pressure but aspirin does not lower blood pressure immediately.

It takes a few hours after taking the aspirin before it starts to lower your blood pressure and regularly taking aspirin can help keep your blood pressure from getting too high and an aspirin a day can help prevent blood clots and prevent heart disease, heart attacks, strokes etc.

Some ways ways to bring your blood pressure down quickly are to exercise, avoid too much salt, drink some lemon water, eat garlic or take some garlic extract supplements.

Laying down and taking some deep breaths can also help lower your blood pressure.

If your blood pressure is elevated and you want to see an immediate change, lie down and take deep breaths.

This is how you lower your blood pressure within minutes, helping to slow your heart rate and decrease your blood pressure.

When you feel stress, hormones are released that constrict your blood vessels.

Drinking water can also bring your blood pressure down and help maintain your blood pressure.

Keeping well hydrated by drinking six to eight glasses of water daily (even more if working in hot and humid conditions) is beneficial for the blood pressure.

Yes high blood pressure can cause and lead to a burst blood vessel in the eye.

Sneezing, coughing, stress, anxiety etc can all cause a burst blood vessel in the eye.

A burst blood vessel in the eye is rarely serious enough to warrant medical attention.

A subconjunctival hemorrhage is usually a harmless condition that disappears within two weeks or so but if not then you should see a doctor.

Stress, high blood pressure, anxiety etc can lead to burst blood vessels in the eye.

The time it takes for a subconjunctival hemorrhage which is a burst blood vessel in the eye to heal is between seven to ten days.

If the burst blood vessel or subconjunctival hemorrhage hasn't healed within 10 days then you should go to urgent care or the emergency room to make sure it's nothing more serious.

But most cases of burst blood vessels in the eye heal on their own within one week to 10 days without any medical treatment.

Although a burst blood vessel in the eye can sometimes seem serious they are mostly not serious enough to warrant any medical treatment.
