Sleep and Time to Conception

Adapted from a press release of the American Society for Reproductive Medicine, October 2018.

For women trying to conceive, going to bed on time may reduce the time it takes to become pregnant.

Researchers from Washington University in St. Louis found that women who were trying to become pregnant, who had more regular bedtimes, took less time to conceive than those whose bedtimes were more erratic.

They recruited women who were planning pregnancy and issued them watches capable of recording the women’s times of sleep onset, waking, and sleep duration.

Participants’ results were divided into groups based on how much their sleep onset time varied from day to day. Women in the lowest variation group had fluctuations of less than 67 minutes in the time they went to sleep each night. Bedtimes for women in the highest variation group varied by more than 138 minutes.

Of 176 participants, 75 were pregnant by the end of the year following the initiation of the study. Participants with less variation in the time they went to sleep had significantly shorter time to conception than women whose sleep onset was less predictable. Neither sleep duration nor wake-up time was associated with shorter time to conception.

This study indicates that, for women planning to conceive, the establishment of regular sleep habits could shorten the time to their conception
