What is Blood Pressure
Blood pressure refers to the pressure exerted by blood against the walls of blood vessels as it flows through them. It is an important physiological parameter of our body, reflecting the efficiency of the heart in pumping blood and the health status of blood vessels. Blood pressure is usually expressed in two values: systolic pressure and diastolic pressure. Systolic pressure refers to the pressure of blood against the arteries when the heart contracts, while diastolic pressure is the period of rest between two contractions of the heart, when blood exerts pressure against the arteries.
How to Measure Blood Pressure
Measuring blood pressure typically requires the use of a sphygmomanometer, which is a common household medical device. During measurement, you need to sit in a quiet environment, ensure your arm is comfortably placed on a table with the cuff around the upper arm, and at the level of the heart. Then, you can follow the instructions on the sphygmomanometer to perform the measurement.
Precautions
While we know what normal blood pressure levels are, it does not mean that our blood pressure should always remain at the same level. Blood pressure can be influenced by many factors such as exercise, diet, stress, etc. If you find that your blood pressure frequently deviates from the normal range, or if you have any concerns about your blood pressure, you should consult a doctor.
In conclusion, understanding and maintaining normal blood pressure levels is crucial for our health. By regularly measuring blood pressure, we can detect and address potential blood pressure issues early, thereby maintaining our physical health.
