Blood Pressure

What is Blood Pressure ?

The force applied by circulating blood on the walls of blood vessels is known as blood pressure (BP). During each heartbeat, BP varies between a maximum (systolic) and a minimum (diastolic) pressure. Each time the heart beats (about 60-70 times a minute at rest), it pumps out blood into the arteries. BP is at its highest when the heart beats, pumping the blood, it is systolic pressure. When the heart is at rest, between beats, BP falls, it is called diastolic pressure.

The most common blood pressure values for a healthy adult human are approximately 120 mmHg systolic and 80 mmHg diastolic. However, normal blood pressure varies from person to person. In some people, the BP levels fluctuate widely, either rising or falling to abnormal levels. As this may lead to other health problems such as heart disease, it is important to always keep BP under control.

The term BP generally refers to the pressure measured at a person's upper arm. It is measured on the inside of an elbow at the brachial artery, which is the upper arm's major blood vessel that carries blood away from the heart.

Common precautions to reduce high blood pressure are :-

  • Stop smoking
  • Keep your body weight at a healthy level.
  • Follow a healthy diet, stressing on fruits, vegetables and low fat dairy foods
  • Get involved in some physical activity.
  • Consume alcoholic drinks in moderation.
