Chills or shaky, jittery feelings during labor are very common. Usually they happen as a woman is going through transition -- that's when her cervix is dilated about eight or nine centimeters -- or sometimes it happens after delivery.The chills are probably caused by a number of things that are happening -- an endorphin release, body temperature changes and/or a reaction to anesthesia. The chills tend to go away about a half hour after labor.
