This is the main cause of aging women; reveal

According to the new study of scientists from Northwestern University Illinois United States, having many children accelerate aging body cells Researchers analyzed data from key markers of cellular aging such as telomere length and epigenetic age in more than 3,000 women between 20 and 22 years of age.

Scientists have revealed that pregnancy accelerates aging between 5 months and 2 years of age and that having more than four or five children increases the risk of suffering from certain diseases and reduces life expectancy.

However, they assert that the epigenetic age of pregnant women during the investigation was younger than they should be. 39; be.
