Blood Pressure first invented by N C Korotkoff a Russian scientist. He heard a sound at the sleeve when a stethoscope placed over the brachial vein at flattened sleeve.
Before that Hales invented a ventilation machine as his most important invention. His contributions to plant and animal physiology were equally significant. At a time when the mechanics of respiration and circulation experiments led to the first understanding of blood pressure. He inserted a tube into a mare’s artery and observed the pulsing of blood into a twelve-foot glass tube. Therefore he is the first person to measure blood pressure.
BP, normal, low or high
Body produces blood in the rib of the body. it runs throughout the body. It receives oxygen from lungs , nutrients from liver and runs throughout the body. As the blood in the body is always in running condition. Requirement of force is necessary . Therefore it needs pressure to make it in running condition. That pressure comes from heart. Heart is the pumping station of the body. It does not take rest from birth to death. blood comes at heart to take oxygen from lungs and then again goes out . Every cell of our body takes their food from this running blood. .https://medlineplus.gov/highbloodpressure.html
Heart is divided into 4 parts. 2 upper (atria ), 2 lower (Ventricles). A wall (septum )separates left and right part. Blood enter in the Rt.atria then goes to lung via R. Ventricles for oxygenation. After oxygenation it goes out for performing his duty for the whole body. In between outgoing and incoming, there are two position are there one high(outgoing) ,other is low (incoming Rt,atria). High position is systolic and low position diastolic is Normal. Normal systolic is 120 mmhg and Normal diastolic is 80 mmhg. Therefore 120/80 is BP is normal. Any BP is lower than this that is low pressure and above this is High pressure.
Reason of high or low BP
as we know pumping of heart creates pressure incoming blood pipes are called veins which is blue in the figure. Outgoing blood pipes is known as artery which is red in colour. If blood faces any Obstacle between incoming and outgoing then pressure differs. Heart to work more. therefore high pressure creates . When blood go slow in running condition then low pressure reflects. Pulse is another factor when blood pushes the wall of the vein affects pulse.
Remedy for BP high or low
Take leafy green vegetable,skinless fish, low fat milk, Maximum 2gms of salt a day . If any medicine started then it has to take life long. skips may fatal. When treatment is going on. we need some blood test 1.LDL (low density lypoprotein ). VLDL ( very low density lypoprotein ). Both increases for irregular lifestyle and foods. Triglyceride is an another factor. HDL ( highDl) is good for us. It acts in our body as soldiers do for their country. Increased HDL is safe for us. There are too many other factors which is unknown to us. Because we cannot make a single drop of blood in factory or laboratory.
There are so many remedy in Ayurveda but my opinion is that we should not take risk. Reason is the hypertension or high BP is dangerous disorder and bears life risk. IT may be fatal or paralysis.
Bp stimulates by meditation.
It is fact that many disorder of our body decreases by meditation. Therefore By practicing it we can get good result. Simultaneously it reduces many disorder alongwith BP. As it fatal or main reason of paralysis. Therefore we should not wholly rely on meditation for BP. While walking if feel head goes backward then consult health provider at earliest. Before that blood pressure show by mete also.
