What the Yuck: Cold water stops my flow

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.

Q: I’ve noticed that when I swim in cold water with my period, it stops. Why?

A: It doesn’t actually stop; the lining of your uterus continues to shed. But the counterpressure of the water can stop the flow from coming out of your body.

Oh, and the temperature of the water has nothing to do with it - this can happen whether you’re in a freezing-cold lake or warm Caribbean waters.

Plus, if you’re floating or swimming horizontally, gravity isn’t able to pull the flow down and out as well as it would if you were in a more vertical position. (The same thing can happen when you’re lying down.)

Once you’re out of the water and standing upright for several minutes, your period should return to normal.
