10 unique facts about the human heart that you need to know

Everyone knows that the heart is the most vital organ owned by humans. The reason is, if the heart stops beating, a person will lose his chance of life. However, only a few people know the unique facts regarding the heart, the key organ of human life. Check out the following heart facts that you must know.

1. The heart size of men and women is different

Men's heart is known to weigh 10 ounces, while women's hearts 8 ounces. You can predict the size of your heart, from how big your fist is. Therefore, the size of the heart of each person is different.

2. The heart is a giant pump

The heart will pump about 5 liters of blood in one minute. Blood flows through the entire vascular system in just 20 seconds. In a day, the heart pumps about 2,000 gallons of blood as far as 60,000 miles into the blood vessels.

3. The average heart beats 60-100 beats per minute

An adult heart beats about 100,000 times each day and 3,600,000 during the year according to American Heart Association . Whereas people who had a shorter heart rate of 60 beats per minute (bpm), their hearts beat about 86,000 times a day.

4. The heart beats slowly when you sleep

At night, the heart will beat below 60 beats per minute. Some people even have only 40 times per minute. This occurs because the body's metabolism is weakened and the parasympathetic nervous system is more active, which slows down the performance of the heart and makes you more relaxed.

5. The symptoms of a heart attack in men and women are different

Not only is a woman's heart smaller than a man's, but women experience heart attacks more slowly than men. When women have a heart attack - and more than half a million women experience it each year - they are more likely to experience nausea, indigestion, pain in the lower chest or upper abdomen, or back pain, than shortness of breath.

6. Daily activities affect the risk of developing heart disease

People who have low activity, such as rarely exercising or moving, have twice the risk of developing heart disease than those who are more active. When you are active even with small movements such as walking from side to side, your muscles activate genes that make chemicals and proteins help process blood sugar and cholesterol more efficiently, thus creating a healthy structure in the walls of blood vessels.

7. Laughter is the best medicine for the heart

When you laugh, the lining of your blood vessel walls relaxes and expands. Laughter sends 20% more blood around your body. One study found that when people watched comedy movies, their blood flow increased. That's why laughter can be an antidote to stress.

8. Heart attacks are more common on Monday mornings

You will be more likely to have a heart attack on Monday morning than any other time. Doctors say that morning is the prime time for heart attacks. This happens because levels of the stress hormone called cortisol increase in the morning.

When this happens, cholesterol plaque that has built up in the arteries can burst and block blood flow to the heart, giving rise to an increase in blood pressure and an increased heart rate due to the stress of getting back to work after a weekend off.

9. Sex can reduce the risk of heart attack

Having sex regularly can reduce a man's risk of dying from heart disease. For men, having orgasms three or four times a week may provide powerful protection against a heart attack or stroke, according to one British study. However, it is unclear whether this applies to women as well.

For one thing, sexual activity is an excellent stress reliever, as well as a means of exercise as it burns about 85 calories per half hour session. If you find it difficult to have sex, it can be a warning that something is wrong with your heart. For example, some researchers think erectile dysfunction may be an early sign of a heart attack.

10 Heart disease can affect anyone

Another heart fact is that heart disease is the biggest killer for both men and women. However, no matter what gender you are, this disease clearly provides equal opportunities for both men and women. Therefore, it is very important to adopt a healthy lifestyle by not smoking, exercising regularly, eating healthy foods, maintaining blood pressure and cholesterol levels, thereby minimizing the chance of developing heart disease from an early age.
