How is blood pressure maintained?
Many factors contribute to controlling blood pressure. Exercise, for one, causes muscles to contract and relax, alternatively squeezing and releasing the blood vessels, causing the blood to move faster and slower. Constant steady movement of the body helps to maintain a regular rhythm in the blood pressure.
This does not mean that people need to do strenuous exercise all day long to stay healthy. Rather, it means that normal bodily movements such as walking, lifting, working or playing can do the job. Straining the muscles can cause the blood pressure to rise as well. Even straining to achieve a bowel movement can create such a rise in pressure.
Blood Vessel Reactions to Natural Remedies
The size of the blood vessels is directly related to the increase or decrease of the blood pressure. The vessels can be dilated or contracted by taking certain types of homeopathic remedies such as vitamin E, coenzyme Q10, L-carnitine, magnesium, calcium, omega-3 fish oil, hawthorn extract, garlic, Ginkgo biloba, grape seed extract and green tea extract. These substances stimulate the contraction-and-release rhythm of the blood vessels to keep the blood pressure at the correct levels to correspond with what you are doing. Daytime levels are naturally higher than nighttime ones. These natural remedies should not be taken in tandem with prescription medications, however, as they can cause the medications to fail or damage to the internal organs. Eating properly and maintaining a healthy weight can help to keep the blood pressure at normal levels, thanks to less stress on the internal organs.
The Nervous System and Blood Pressure Control
Electrical stimulus can help control blood pressure. When the nerves in the veinous system sense that the blood pressure is falling too low, they send signals to the central nervous system. These sensors are called baroreceptors, which signal the brain to either increase cardiac pumping or restrict the blood vessels to increase the flow of blood through them. By the same method, if the pressure gets too high, the brain instructs the vessels to open up to slow the flow of blood and the heart decreases its rhythm to keep the pressure stabilised. Hot and cold temperatures also have an effect on the diameter of blood vessels, causing a differential in the blood pressure itself. Applying heat or cold directly to the skin can cause mild dilation or constriction of the vessels in that region.
