What is A Normal Blood Pressure Level in a Human?
The normal blood pressures are believed to be somewhere around 120/80 mm of Hg, whereby 120 is the systolic pressure, i.e. the numerator while 80 is the diastolic pressure, i.e. the denominator. The pressure of the blood changes in each of us throughout life, and on a minute-to-minute basis. It tends to get higher as we age, and is usually lowest when we sleep. As we go through a normal day, it fluctuates and becomes elevated in response to stress, pain, hormonal levels, meals and exercise. These are normal responses to our environment. The human heart pumps blood through the blood vessels in a wave-like pattern. The peak of the wave corresponds to the heart’s contraction. The pressure of the blood at the peak of the heart’s contraction is known as the systolic blood pressure. When the heart relaxes, the pressure of the blood falls, and a lower level of blood pressures occurs, known as the diastolic blood pressures. This systolic and diastolic blood pressures are measured at routine do
