A novel study indicates that engaging in social activities such as participating in board games or singing, diminishes levels of the stress hormone ACTH in women who do not use contraceptive pills. This effect, however, is absent in women who do. The findings suggest that birth-control pills might interfere with the body’s natural mechanisms for managing stress, possibly due to their role in hormone modulation.
The use of contraceptive pills among women dates back to the 1960s, yet the multifaceted interactions between these hormone-based tablets and the human body remain incompletely understood.
Scientists from Aarhus University along with their American colleagues conducted an investigation to assess the stress response in a sample of 131 young women during blood sampling. The study encompassed women who were both on and off birth control pills. The researchers specifically zeroed in on ACTH levels in the women’s blood.
Results demonstrated that a 15-minute period of social interaction post blood sample collection led to a decrease in stress hormone levels in women not using birth control pills. Conversely, no such reduction was observed in women using these contraceptive tablets.
In order to minimize additional stress to participants, an intravenous catheter was used for the first blood sample, allowing subsequent blood sampling to occur without additional needle pricks post social activities.
“Our findings can potentially lead to more effective treatment and prevention strategies for stress-related conditions in women. Moreover, this research expands our understanding of how gender and stress hormones interact,” states Michael Winterdahl, a visiting scholar at the Translational Neuropsychiatry Unit at the Department of Clinical Medicine.
In the study, participants had an average age of 20.5 years. After the initial blood sample, they engaged in a variety of group activities, ranging from board games to church services.
Winterdahl adds, “Social interaction is a potent stress reliever. These findings are crucial as they demonstrate that birth control pill users do not experience the same reduction in stress hormone levels through social activities as those who are not on the pill.”

Competing Theories
Unlike previous studies focusing predominantly on cortisol levels under extreme conditions, this research measured ACTH levels, which change more swiftly than cortisol, allowing for the observation of rapid changes in stress responses.
The study represents a novel approach to exploring how birth control pills impact the stress response by examining ACTH levels during social activities.
“Our research edges us closer to a better understanding of the complexities of stress regulation in the brain, specifically related to ACTH dynamics,” says Winterdahl.
The study confirms that birth control pills have an impact on the hypothalamic-pituitary-adrenal (HPA) axis, which is a critical pathway for stress signal transmission from the brain to the adrenal glands. Despite this, the reason for the observed disparity in stress hormone reduction among pill users and non-users during social activities remains inconclusive.
Winterdahl states, “We hypothesize that contraceptive pills may suppress the body’s natural production of progesterone, a hormone that breaks down into allopregnanolone, known to exert calming effects and influence stress responses.”
Phase-Related Differences
The study included women at various phases of their menstrual cycles and noted that stress responses in non-pill users were influenced by their cycle phases. For example, women in the proliferative phase, following their menstrual period, did not experience a reduction in ACTH levels when engaging in stress-reducing activities.
Winterdahl elaborates, “During the proliferative phase, progesterone levels are typically low, which results in limited conversion to the calming hormone allopregnanolone. This could explain why ACTH levels remain unaffected in women who are not on birth control pills immediately after their menstrual period.”
He also indicates that the stress response appears to be disconnected in women on contraceptive pills, and cannot adapt to specific situations. Further studies are needed to clarify the intricate mechanisms linking hormone levels and stress response.
“It is essential to note that contraceptive pills serve multiple functions and come in various formulations, which means they have differing side-effect profiles. Therefore, further research involving a larger and more diverse set of participants is vital,” concludes Winterdahl.

Frequently Asked Questions (FAQs) about birth control pills and stress management
What is the main finding of the new research on birth control pills?
The primary discovery of the study is that birth control pills may interfere with the body’s natural ability to manage stress. Specifically, social activities reduced ACTH stress hormone levels in women not on contraceptive pills, but had no such effect on women who are using them.
Who conducted the study and who were the participants?
The study was conducted by a team of scientists from Aarhus University and their counterparts in the United States. The participants consisted of 131 young women, both users and non-users of birth control pills, with an average age of 20.5 years.
What methodology was used in the study?
The researchers collected blood samples from 131 young women to measure the levels of the stress hormone ACTH. After the initial blood sample was taken, participants engaged in 15 minutes of various social activities like playing board games or attending church services. A second blood sample was then taken to assess any changes in ACTH levels.
How did birth control pills affect stress hormone levels?
The study found that women who were not using birth control pills experienced a reduction in ACTH stress hormone levels after engaging in social activities. However, those who were on contraceptive pills did not show any reduction in their ACTH levels.
What is ACTH and why is it significant in this study?
ACTH stands for Adrenocorticotropic Hormone. It is significant because it acts as a neurotransmitter that controls the body’s stress response mechanism. In this study, ACTH levels were used as an indicator of how effectively the body is managing stress.
How does this study differ from previous studies on stress hormones?
Unlike previous studies that focused predominantly on cortisol levels under extreme conditions, this study specifically measured ACTH levels, which change more swiftly than cortisol, thus allowing the researchers to observe rapid changes in stress responses during social activities.
What are the implications of these findings for stress-related conditions in women?
The findings could potentially lead to more effective treatment and prevention strategies for stress-related conditions in women. However, more research is needed to understand the full implications.
Does the study make any hypotheses about why birth control pills affect stress management?
Yes, one of the hypotheses suggested by the researchers is that birth control pills may suppress the body’s natural production of progesterone, a hormone that influences stress responses.
Are further studies needed to confirm these findings?
Yes, the study calls for additional research involving a larger and more diverse set of participants to validate these findings, especially given that birth control pills come in various formulations with differing side-effect profiles.
What is the relevance of the menstrual cycle phase in this study?
The study notes that women who are not on birth control pills experience stress responses that are influenced by the phase of their menstrual cycle, especially during the proliferative phase when progesterone levels are low.

I’ve been on the pill for years and honestly, it kinda explains a lot. Stress management has always been a struggle for me. Makes me reconsider my choices.
This is concerning, especially for women who are already dealing with stress-related issues. Could this mean changes in prescriptions for birth control?
Wow, this is eye-opening. Never really thought birth control pills could have such an impact on stress management. Makes ya think, huh?
Super interesting. The whole hormone regulation thing is complicated but this research could be a game changer. Would love to read more studies like this.
So many unknowns still… But the article does a good job of breaking down complex biochemical processes. Definitely think more research is needed tho.
I wish this kind of information was more readily available before. Women should know all the pros and cons of birth control pills, not just the contraceptive aspects.
Didn’t knw that birth control pills could affect the body’s natural stress responses. Really gotta pay attention to the side effects of medication.
