\" \" A new study has shown that the cells of women who've had multiple pregnancies age faster than women who've had no pregnancies. According to a study published in late July in the journal Scientific Reports, multiple pregnancies may make your cells age more quickly. They looked at two specific markers of age: telomere length and epigenetic age. But while women are pregnant, the researchers were surprised to find, their cells actually appear younger than their chronological age. All the same, when women had multiple pregnancies, their cells began to appear older — from about 6 months to 2 years older for each pregnancy.
