In life, except for blood donation and trauma bleeding, blood loss is generally not much, at most it is only nosebleeds and blood draws for blood tests, does this small degree of blood draw have any effect on the body?

Does blood sampling have any effect on the body?

Blood sampling can have certain effects on the body. Blood is the body's transport equipment, the human body in the blood accounted for a large proportion, accounting for 7 to 8% of the body weight, the total amount of 4200 ~ 4800ml, a one-time blood draw as long as not more than 10% of the total amount of blood generally will not be harmful to the body, but will be beneficial, but some people are poor health, the amount of blood is very small, the blood draw will appear dizziness, blood fainting, shock and other discomfort.

What are the health benefits of blood draws

Promotes blood regeneration

After the total amount of blood is changed it will stimulate the hematopoietic system and will promote the regeneration of blood, a phenomenon that is good for people in general, the renewal of blood, which enhances the ability to carry nutrients and strengthens one's physical strength.

Increased survival rate

In some special cases, hospitals will give priority to blood transfusions according to individual blood donations. For example, when serious trauma causes hemorrhage, people who donate more blood will have dozens of times greater chances of survival, so just in case, it is better to make more contributions and donate more blood.

Reduce blood viscosity

The total amount of blood will be replenished in a short period of time, and the most replenished is water. People with high blood lipids will have their blood lipids diluted for a period of time after the blood draw, and their blood viscosity will drop, so regular blood draws and blood donations for people with high blood lipids will help lower their blood lipids to some extent.

What is the harm of blood sampling to the body

Anemia

The most obvious one is the lack of oxygen in the blood, and the brain often becomes dizzy from lack of oxygen, especially after eating, and some people even experience anemia and shock.

How to replenish blood after a blood draw

The regeneration of blood requires a lot of protein and the mineral iron, so pay attention to iron and protein supplementation in life. In addition, blood loss can be directly consumed other animal blood, such as chicken blood and pig blood, which have a better blood replenishing effect. Black sesame, red dates, pig's liver, lotus root, cinnamon, black beans, wood ear, etc. in life are all qi and blood replenishing foods.
