A variety of things can affect blood circulation: blood vessel health, blood pressure, thyroid function, hydration, heart health, exercise, and blood viscosity. (More on this in a moment.)
Potassium, on the other hand, is an important mineral (and electrolyte) that helps the body get rid of sodium through the urine, which helps reduce your blood pressure. Related: 8 Foods With More ...
Blood viscosity is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood. This biophysical property makes it a critical determinant of friction against the vessel walls, the rate of venous return, the work required for the heart to pump blood, and how much oxygen is transported to tissues and organs.
There is an ongoing medical debate over what is the optimal level of blood pressure to target when using drugs to lower blood pressure with hypertension, particularly in older people. [ 13 ] Blood pressure fluctuates from minute to minute and normally shows a circadian rhythm over a 24-hour period, [ 14 ] with highest readings in the early ...
A 2021 study found that yogurt could help reduce blood pressure due to its high concentration of micronutrients calcium, magnesium and potassium, which are all associated with a lower risk of ...
Substances called vasoconstrictors can reduce the size of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitroglycerin) increase the size of blood vessels, thereby decreasing arterial pressure. If the blood viscosity increases (gets thicker), the result is an increase in arterial pressure.
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.

How a varicose vein forms in a leg. Figure A shows a normal vein with a working valve and normal blood flow. Figure B shows a varicose vein with a deformed valve, abnormal blood flow, and thin, stretched walls. The middle image shows where varicose veins might appear in a leg.
