[Explanation by eMedTV.com]
It is the 'pressure' in your blood vessels
between heartbeats (when your heart is resting). This is represented by the
bottom number, in a blood pressure reading. It will be
considered 'low', when the BP reading is below 60. Likewise, it will be considered 'high' if the BP reading is higher than 90. Thus, in order to maintain a good level, it is suggested that one should change their lifestyle, such as losing weight and regular exercise.
What is blood pressure
then ? It is actually the amount of 'force' that blood exerts on the walls of our
blood vessels, as it passes through them. There are two types of pressure
measured, namely :
1) pressure, while the heart is beating (known as systolic blood pressure);
2) pressure, while it is relaxed (known as diastolic blood pressure).
- Level of exercise
- Amount of tension
- Nicotine useHowever, it is best to take several BP readings,
in order to derive a person's average blood pressure.
Importance of Diastolic Blood Pressure*
When blood is pumped from your heart into your blood vessels, sufficient diastolic blood pressure is created to send it to all other parts of your body. As blood vessels travel away from the heart, they branch off and gradually get smaller, just like tree branches. One branch may go to the brain, while another may go to your kidneys. Diastolic blood pressure keeps the blood flowing through all these branches so your body's cells get the oxygen and nutrients they need, and waste matters can be removed.
If the diastolic pressure is too low (low blood pressure), the blood is not able to bring oxygen and nutrients to all the body's cells, and remove waste matters. This can cause the cells to die. The diastolic blood pressure is considered low when the blood pressure reading is below 60.
*For those with high diastolic blood pressure, lifestyle changes are the first component of treatment. Such changes will help to lower diastolic blood pressure. Incidentally, they also help to improve a person's quality of life. Some of such changes known, to lower blood pressure include:
- Weight loss;
- Regular exercise;
- Consume more fruits and vegetables & reducing fats and cholesterol;
- Reduce salt intake in the diet; &
- Cut down alcohol intake.
