ATLANTA (CBS Atlanta) - New research suggests that the phenomenon of premenstrual syndrome, known more commonly as PMS, may not occur the way many have thought over the years.
Researchers working under the direction of Dr. Sarah Romans of the University of Otago in New Zealand asserted that the correlation between an impending menstrual cycle and symptoms such as mood swings is far more tenuous than previously stated, according to Time Health & Family.
“The human menstrual cycle … has historically been the focus of myth and misinformation, leading to ideas that constrain women’s activities,” authors of the study wrote. “We wished to examine one pervasive idea, that the [menstrual cycle] is a cause of negative mood, by studying the scientific literature as a whole. We briefly reviewed the history of the idea of premenstrual syndrome and undertook a systematic review of quality studies.”
