The heart is the muscular organ that is at the center of the cardiovascular system. He is in charge of pumping blood, through the whole body and delivering nutrients and oxygen.
Despite its small size, the heart must do an arduous job to be able to pump the liters of blood required for the proper functioning of the human system.
So that you are sure that you are doing the best to care for and protect your heart, know 6 surprising truths that make the heart can perform its functions within the body and how it can be affected by emotions.
6 Surprising truths of the heart
1.Work hard without resting
The heart of a baby begins to form from the fourth week of its development, from that moment begins to work without resting. Some people believe that the heart pauses when sneezing, however that theory is not scientifically proven.
On the other hand, incredible as it may seem, some research says that a woman’s heart rate is faster than that of a man, since she can perform eight beats per minute. This means that, depending on the sexual gender, a person’s heart can beat about 100,000 times a day and 40 million times a year.
2.It has its own energy charge
The heart is so amazing that it does not require the other parts of the body to beat. In fact, if the heart separates for a few seconds from the body, it would keep beating because it contains its own electrical supply.
This phenomenon occurs because the myocardium (the muscle of the heart) sends the electrical impulses that cause the heart to contract. In this action, the sinus node also participates, also known as ” natural pacemaker “.
3.It is a powerful blood pump
Although the heart is a small muscular organ, it is very powerful, since it has the capacity to pump more than 300 liters of blood through the body every hour . That means that in the course of 75 years, the heart will be able to pump around 1 million barrels of blood.
4.Pumping blood quickly to all body cells
In the human body there are 75 trillion cells, and the heart is in charge of pumping the blood to all of them except the corneas.
It is surprising that when the body is at rest, the heart takes only six seconds for blood to flow from the heart to the lungs and back; eight seconds to go to the brain and back; and 16 seconds to go to the toes and vice versa.
5.Emotions can trigger cardiomyopathy
Despite being so powerful the heart can be affected by emotions, such is the case of cardiomyopathy.
Cardiomyopathy is a disease that attacks the heart muscle and causes the heart to increase in size and become stiffer and thicker than it normally is. This disease is commonly known as the “broken heart syndrome “.
Research says that the emotional charge can cause these physical changes in the heart and trigger a stress cardiomyopathy. This disease occurs when a stressful emotional event induces some symptoms similar to those of a heart attack such as shortness of breath and pain in the chest.
In addition to this, one study found that people who have lost a loved one have a higher risk of suffering from atrial fibrillation, or the development of an irregular heartbeat. Within the first year this risk is especially high among younger people and if the loss was sudden or unexpected.
Many people believe that nothing but pain emotions trigger this type of illness, however, a recent study in the European Heart Journal found that happy events like surprise parties or winning the lottery can put a sudden strain on the heart – a condition which has been baptized as “happy heart syndrome “, which seems to affect mainly postmenopausal women.
6.Cold climates can affect the heart
When people are traveling through cold or stormy weather stations, the heart begins to make a greater physical effort because it begins to decrease the internal heat of the body.
The American Heart Association recommends that, to take care of the heart, wear coats and hats in cold or windy climates to keep warm and prevent the heart from pushing harder than normal.
