Clinical studies link having more children with faster biological aging and shorter lifespans. Biological aging peaks between having no children and having many children. The optimal longevity range is two to three children, with pregnancies occurring between ages 24 and 38. High fertility is believed to accelerate cellular aging in mothers due to energy expenditure and physiological stress from pregnancy and child-rearing. Research also connects additional pregnancies with shorter telomeres and higher epigenetic age, indicating increased cellular aging with each child. These findings suggest that reproductive preferences may be influenced by longevity considerations.
"Clinical studies find that having more children is associated with faster biological aging and shorter lifespans. The optimal range for longevity is two to three kids, among those who had their pregnancies between the ages of 24 and 38. 1 It is believed that high fertility causes accelerated cellular aging in mothers due to the significant energy expenditure and physiological stress of pregnancy and child-rearing. 2 Be still your Play-Doh'd heart: There's more."
"Research specifically showed that women with more pregnancies had shorter telomeres (protective DNA caps, like plastic tips on shoelaces) and higher epigenetic (biological) age with each additional child, potentially aging a mother's cells by up to t"
