Birth-control pills affect the body's ability to regulate stress : Researchers
Women have used birth-control pills since the 1960s, but researchers still do not know everything about the body's complex reaction to the small, hormone-laden pill.
Researchers from Aarhus University and the United States have studied the stress response of 131 young women when having a blood sample taken. Some of the women were on birth-control pills, while others were not. The researchers specifically measured the levels of the stress hormone ACTH in the women’s blood.
