A low blood pressure or also termed as hypotension is when the blood pressure is low enough that there is inadequate blood flow to the organs of the body.
The Basic Components of the Human Blood
To fully understand how blood delivers the essential substances like nutrients and oxygen to the body’s cells, let us first know the basic components of the human blood. These include the red blood cells, platelets, plasma, and the white blood cells.
The red blood cells comprise 40% to 45% of the human blood volume.It generates from the bone marrow and has about 120 days life cycle in the body. Platelets, on the other hand, are the smallest part of the blood cells that look like small plates. The role of the platelets is that they control the bleeding whenever there is wound in the body. The moment wound occurs, our blood vessel will send a signal that platelets will receive so that it can travel into that area to form clusters in order to plug the wound right until it heals.

Plasma is the yellowish liquid part of the blood. Although made up mostly of water, it also holds salts, hormones, sugars, and proteins. It assists in transporting the nutrients and water to the body tissues.
Lastly, the white blood cells account about 1% of the blood. Even with such percentage, the leukocytes or WBC are essential for protection against disease and illness. WBC also promote good health and attack the foreign bodies, such as the bacteria and viruses, found in the bloodstream.

How Does the Blood Pressure Work?
Blood pressure, as the name suggests, is the pressure of the blood on the arteries' walls as the heart pumps blood all throughout the body. BP is an important part as to how circulation and the heart works. It is natural that the blood pressure goes up and down because it is adjusting to the needs of the heart, depending on the physical activity of the person.
When blood pressure is higher than normal, it is considered as a high blood pressure. The favorable blood pressure reading is below 120/80. However, there is hypotension when the blood pressure is less than 90/60.

Blood Pressure vs. Pulse Rate
Blood pressure and pulse rate or heart rate are two indicators of health. They are separate measurements, which means that the blood pressure and heart rate do not necessarily increase at the very exact time. Even if the pulse is beating more times than the normal minute, healthy vessels just get larger to enable more and easy blood flow. When a person exercises, the pulse also speeds up.
In short, taking your pulse rate does not suggest low or high blood pressure.

What is Blood Pressure Monitoring?
Doctors often suggest their patients undergo a blood pressure monitoring by wearing a BP monitor for 24 hours during sleep and day-to-day activity. It utilizes a small digital BP machine that can be attached to a belt around the body that is connected to the cuff on the upper arm. This easy-to-wear and light-weight monitor will help the doctor to determine the accurate information about the person’s blood pressure.

When is There Hypotensive Breathing?
Hypotensive breathing is a respiratory impedance. This can happen to individuals who are suffering from a reduced central blood volume. It affects the cardiovascular system, depending on the cause of the reduced blood volume.

Low Blood Pressure Exercise Tips
A low blood pressure exercise is an effective way to control the blood pressure. While it may trigger the associated symptoms linked to the drop of blood pressure because the muscle needs more oxygen and blood during exercise, it does not mean that people with low blood pressure should avoid keeping fit and healthy. What is important is to begin the exercise routine slowly and also gradually slow down before you end the exercise.
Low blood pressure exercises can include resistance exercises and aerobic. These exercises include rowing, swimming, walking, jogging, cycling, lower limb resistance training, pilates, and light weight-lifting. If you are into yoga, avoid moving from the supine poses to seated poses or from seated poses into standing poses. The yoga poses that involve twisting are the ones more suitable for people with low BP.
