Can I reduce my blood pressure by draining some blood?
In: Biology
Yes, temporarily. Blood pressure drops with blood loss. If it drops below a certain point then your heart can’t get blood to the brain. The body doesn’t like this, and so will typically respond by making you get very thirsty so it could then add the fluid you drink to your circulatory system.
Draining blood doesn’t address the systemic problems that typically are responsible for high blood pressure like a high sodium diet or stress. If the problems leading to high blood pressure aren’t taken care of, it’ll just return soon after. It’s a very poor temporary solution to the problem.
