Have you ever heard this old wives' tale: If you have heartburn during pregnancy, it means you will have a hairy baby. That may sound way too far-fetched to be legit, but according to a study done at the Johns Hopkins University, there is a correlation between the two. The study followed 64 women--all pregnant. About 78% of the women suffered from heartburn during their pregnancy, and once the babies were born photos of the newborns were given to third-party participants to rate on the scale of "hairy" to "not hairy".

Of the 12 women who reported that they suffered from NO heartburn, 10 of the babies were born with no hair--or very little. How extra-hairy babies cause heartburn, doctors still aren't certain. All they know is that there is a legit correlation between heartburn in pregnant women and hairy babies!
