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.)
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.
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.
The first risk is related to blood viscosity. [1] The blood viscosity refers to the resistance to the movement of blood. It is vital to sustaining the vascular homeostasis in disease prevention and medical treatment. [14] Besides, the blood viscosity is greatly influenced by distinct factors, such as haematocrit, the degree of aggregation of ...
The superfood is a good source of potassium, fiber, and the antioxidant lutein — all things that can relax blood vessels and lower blood pressure. Spinach is also magnesium-rich, which has been ...
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 ...
Vasodilation plays a major role in immune system function. Wider blood vessels allow more blood containing immune cells and proteins to reach the infection site. Vasodilation occurs as part of the process of inflammation, which is caused by several factors including presence of a pathogen, injury to tissues or blood vessels, and immune ...
The Fåhræus–Lindqvist effect (/ f ɑː ˈ r eɪ. ə s ˈ l ɪ n d k v ɪ s t /) or sigma effect [1] describes how the viscosity of blood changes with the diameter of the vessel it travels through. In particular there is a decrease in viscosity as the vessel diameter decreases, but only at small diameters of 10–300 micrometers (mainly ...
