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.)
To put this into perspective, some research shows that reducing your systolic blood pressure (top blood pressure reading) by 5 mmHg may lower your risk of cardiovascular events by 10%! The Bottom Line
Over time, high blood pressure can cause damage to the arteries that can lead to health conditions including stroke, heart disease, kidney problems and dementia. There are multiple risk factors ...
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. [4]
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 ...
For this reason, Cunningham emphasizes the importance of yearly blood panels that can help identify if your symptoms warrant further investigation. Heads up: Depleted energy levels affect us all.
Normal blood vessel (left) vs. vasodilation (right) Vasodilation, also known as vasorelaxation, is the widening of blood vessels. [1] It results from relaxation of smooth muscle cells within the vessel walls, in particular in the large veins, large arteries, and smaller arterioles. [2]
