Body Position Affects Heartbeats
Heart is one of the most important organ, this organ serves to pump blood through the arteries to the tissues and other organs in the body.
It takes less than 60 seconds for the heart to pump blood around the body’s cells and the heart will continue beating before the baby is born until they die.
According to the American Heart Association (AHA), resting heart rate is the number heart beats per minute when a person is resting. In most cases, one’s resting heart rate are around 60-100 beats per minute.
Someones heartbeat depends on various factors, such as cold weather, altitude, level of fitness and hydration status of a person. But postures such as sitting, standing or lying down also affects how fast the heart beats per minute.
When someone is lying, then the heart will beat less than when they are sitting or standing. It is because when people are lying, then the effect of gravity on the body is reduced which makes more blood flows back to the heart through blood vessels.
If there are more blood returning to the heart, then the body is able to pump more blood per beat. This means the heart beats per minute needed to meet the needs of blood, oxygen and nutrients will be minimal.
However, heart rate will increase when a person stands, because the blood returning to the heart would be less. This condition may cause a sudden increase in heart rate when a person moves from sitting or lying to a standing position.
In some individuals, especially the elderly, such rapid change in position from lying to standing can cause the body to become dizzy or even faint. Because this rapid movement makes the heart unable to pump enough blood to the brain.
When falling or fainting one should be in a lying position, which is an advantageous position for the heart because of the effects of reduced gravity and more blood flowing to the brain.
