A new study suggests that women who work more than forty hours a week, or frequently lift heavy objects, may not get pregnant as fast as women who don’t. Researchers observed 1,739 nurses who tried to get pregnant, and estimated 16 percent of them will fail to conceive within 12 months, and five percent still hadn’t conceived after two years.
Women who worked more than 40 hours a week were linked with taking 20 percent longer to get pregnant, as compared to women who only worked 21 to 40 hours. Lifting and doing other similar physical activities with at least 25-pounds, several times a day, were also tied to delaying pregnancy, lengthening the time of having a baby to nearly 50 per cent.
According to the lead researcher, Audrey Gaskins, who’s a researcher at Harvard University, she says “Our results show that heavy work, both in terms of physical strain and long hours, appears to have a detrimental impact on female nurses’ ability to get pregnant.” Some women are forced to work more than 40 hours a week, but they should be more aware of the risks.
