Having two or more children can cause heart diseases to both the father and mother. One child is a source of comfort and protection for the parents but two or more children can increase economical strain, a new study reveals.

For mothers, multiple pregnancies mean rapid changes in hormones and for fathers, more stress. New researchers have found a new factor to be added in the already existing factors responsible for increased heart diseases. The study included 500,000 people and discovered that there is a close link between the number of children and coronary heart diseases - the leading cause of death, according to Daily Mail.

Parents are at less risk with one child but multiple pregnancies put the heart at risk. The body would start reacting to additional cardiovascular risk factors because of the alteration that happens in the body due to multiple pregnancies.

But the study does not focus on biological factors only; it highlights socioeconomic factor, too. Based on the data of this new study, the number of children will be a future focus of investigations. One child provides many benefits to the parents including protection but two or more would double the financial burden and stress.

There are many factors for heart diseases and when they "gang up" and become worse, the results are dire. Having one factor only means you have double risk of coronary heart disease but having two factors mean the risk is fourfold. If you smoke and have diabetes, you have a greater risk of heart disease, reports NIH.

Another study found that bearing more than one child puts a woman at risk in later years of life. She suffers from irregular heartbeat which is known as atrial fibrillation. This ultimately leads to blood clots, stroke and heart failure.

Researchers from McMaster University, Canada, and Brigham and Women's Hospital, Boston, assessed 34,639 participants. The study revealed that women who had been through four or more pregnancies were 50 percent more vulnerable to heart diseases. Circulation published that hormonal changes in the body during pregnancy explain the link of child bearing to coronary heart disease (CHD).
