Get More Sleep, Get Pregnant Faster?

No news here: We need to sleep to ... well, function. Maintaining a regular sleep schedule will not only help you feel more rested in the morning, fall asleep faster at night and, as it turns out, it could help you get pregnant quicker, according to a new study.

The results of a recent study by researchers at Inje University in South Korea were presented at a conference of the American Society for Reproductive Medicine. They showed that women who got between seven and eight hours of sleep each night and stayed on a normal sleep regimen boosted their chances of conceiving.

The study examined the sleeping habits of over 650 women who were receiving IVF treatment (though researchers believe the results would be similar for women who weren't doing IVF, too). Those who slept just seven or eight hours were 25 percent more likely to get pregnant than those who slept nine or more hours, and 15 percent more likely than those who got less than seven hours of sleep. Dr. Daniel Park presented the findings and said, "Most commonly, people think that sleep can only have a good impact on fertility, but my study showed excessive amounts—more than eight hours—can be bad."

Researchers are unsure as to why sleep habits affect fertility, but they think it could be because of lifestyle habits or certain hormones produced during sleep. Women who sleep too much could have unpredictable schedules—drinking, not exercising, etc.—and those who get too little sleep could be stressed (which also hinders the ability to get pregnant). Also, certain hormones are produced with too much sleep—or too little.
