Hormonal imbalances are becoming increasingly common, affecting many individuals with a range of distressing symptoms. These symptoms can include night sweats, sleep issues, anxiety, hair loss, skin and vaginal dryness, and low sex drive. The prevalence of these issues is significant, with estimates indicating:
- Approximately 20 million Americans have some form of thyroid disease, with up to 80% of these cases occurring in women.
- Between 2-6 million men in the U.S. suffer from low testosterone levels.
- Around 6-12 percent of U.S. women of reproductive age are affected by polycystic ovarian syndrome (PCOS), which disrupts hormone levels and can lead to irregular menstrual periods, excess hair growth, and weight gain.
A critical yet often underestimated factor in maintaining optimal hormonal health is the management of stress. Stress is an inevitable part of life. However, when the body remains in a prolonged state of stress, it can lead to bodily dysfunction and degeneration. The primary hormone produced in response to stress is cortisol. Elevated levels of cortisol can increase blood sugar, affect inflammatory markers, and impact vital organs such as the thyroid and reproductive organs, resulting in further hormonal imbalances.
To achieve optimal hormone health, it is essential to address stress and regulate the autonomic nervous system. For more applicable tools on regulating the nervous system, check out my Masterclass on Nervous System & Stress Support, where I delve into the role of stress and trauma in chronic disease.
The Autonomic Nervous System’s Role in Stress Response
The autonomic nervous system (ANS) operates automatically, managing vital functions such as heart rate, digestion, respiratory rate, pupillary response, and more, without the need for conscious effort. It consists of two main branches: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The SNS, often referred to as the “fight or flight” system, prepares the body to respond to perceived threats by increasing heart rate, dilating airways, and redirecting blood flow to muscles. In contrast, the PNS, known as the “rest and digest” system, promotes relaxation, reducing heart rate, enhancing digestion, and conserving energy.
Chronic stress can disrupt the balance between these two branches, often tipping it toward sympathetic dominance. This state of constant alertness can be detrimental to overall health, leading to issues such as high blood pressure, anxiety, digestive problems, and impaired immune function to simply name a few. Prolonged activation of the SNS depletes the body’s resources, undermining the restorative and regenerative functions governed by the PNS.
Heart rate variability (HRV) serves as a crucial indicator of autonomic nervous system health. HRV measures the variation in time between consecutive heartbeats, reflecting the body’s ability to adapt to changing circumstances. A higher HRV is associated with greater flexibility and resilience, indicating a well-balanced ANS and a greater capacity to manage stress. On the other hand, a lower HRV suggests reduced adaptability and potential autonomic imbalance.
Many wearables available today, like the Oura Ring and Whoop, track HRV and offer valuable insights into daily stressors and how the body is adapting and recovering. By monitoring HRV, individuals can gain insights into their stress levels and autonomic function. Practices such as meditation, rhythmic breathing exercises, sauna bathing, and regular physical activity can enhance HRV, promoting a healthier balance between the sympathetic and parasympathetic systems – both acting as major players when it comes to our hormonal systems.
What Happens When We’re Stressed? The HPA Axis and Cortisol
The hypothalamic-pituitary-adrenal (HPA) axis is a central component of the body’s response to stress, involving the hypothalamus and pituitary gland in the brain, and the adrenal glands above the kidneys. This system is critical for maintaining homeostasis and ensuring survival in the face of stressors. When the body perceives stress, the hypothalamus releases a hormone called corticotropin-releasing hormone (CRH). CRH then travels to the pituitary gland, prompting it to secrete a secondary hormone called adrenocorticotropic hormone (ACTH). ACTH then travels through the bloodstream where it subsequently stimulates the adrenal glands to produce and release cortisol, the primary stress hormone. It is inside the adrenal cortex at the level of the mitochondria that cortisol is synthesized.
Cortisol is essential for survival as it helps mobilize blood sugar and influences energy metabolism, ensuring the body has the necessary resources to respond to stress. It also affects immune function, reducing inflammation and aiding in the body’s recovery from stress. However, when cortisol levels remain chronically elevated due to persistent stress, it can lead to several adverse effects.
Chronic cortisol elevation impacts blood sugar regulation. By promoting gluconeogenesis, which is the process of making glucose from protein breakdown, and inhibiting insulin secretion, high cortisol levels can lead to high blood sugar and increase the risk of developing insulin resistance and type 2 diabetes. Elevated cortisol also reduces protein synthesis, impairing muscle growth and repair and potentially leading to muscle wasting over time.
Cortisol alters overall metabolism by promoting fat storage, particularly in the abdominal region, which is associated with increased cardiovascular risk. It also suppresses the function of the thyroid gland, reducing the production of thyroid hormones that regulate metabolism. This suppression can lead to symptoms such as fatigue, weight gain, and depression.
Chronic cortisol elevation can also disrupt the balance of sex hormones like progesterone and testosterone. In women, this may result in irregular menstrual cycles, reduced fertility, and symptoms of estrogen dominance, such as weight gain, painful menses, and mood swings. In men, it can lead to decreased testosterone levels, contributing to reduced libido, stunted muscle growth, and low energy.
Supporting Your Adrenal Glands
Since the adrenal glands are responsible for the synthesis and release of cortisol, supporting these hat-shaped glands atop the kidneys is crucial for effective stress management. Additionally, the adrenal glands secrete other important hormones such as epinephrine (adrenaline), norepinephrine, dehydroepiandrosterone (DHEA), and aldosterone. When faced with chronic stress, these glands can become overworked, leading to hypothalamic-pituitary-adrenal (HPA) axis dysfunction and a host of related health issues.
Adaptogens are natural plant substances that help the body adapt to stress and exert a normalizing effect upon bodily processes. Two well-known adaptogens, ashwagandha and rhodiola, have been extensively studied for their ability to modulate the body’s stress response. Ashwagandha (Withania somnifera) is a medicinal herb that has been used for centuries, tracing back to Ayurvedic medicine. It has been elucidated in the literature to lower cortisol levels, reduce perceived stress and anxiety, and improve overall mood and cognitive function. Rhodiola (Rhodiola rosea), another common adaptogen, enhances the body’s resilience to stress by improving its ability to adapt. This helps buffer the threshold of stress reactivity, thereby reducing the likelihood of burnout while still maintaining a sense of energy.
Adaptogens work by supporting the HPA axis, which regulates the stress response. By promoting balance within the HPA axis, ashwagandha and rhodiola help maintain optimal cortisol levels and support adrenal health. This enhanced resilience not only mitigates the effects of stress but also promotes overall well-being and energy levels.
Incorporating adaptogens into your daily routine can be a beneficial strategy for managing stress and supporting adrenal function. To help you get started, I have curated a selection of my favorite supplements in my Stress Support Protocol. You can explore these recommendations and purchase high-quality adaptogens through my Fullscript dispensary.

Mind-Body Exercises and Mindfulness
Engaging in mind-body exercises and mindfulness techniques is an effective way to significantly reduce stress and enhance overall well-being, which will ultimately have a positive impact on your hormonal system. Practices such as yoga, meditation, and intentional breathing exercises are particularly beneficial as they not only improve heart rate variability (HRV), but also promote a parasympathetic state, which is essential for relaxation and recovery.
Yoga combines physical postures, breathing exercises, and mindfulness to create a holistic approach to stress management. Regular yoga practice helps increase flexibility, strength, and balance while simultaneously calming the mind. The focused breathing and mindful movements involved in yoga stimulate the parasympathetic nervous system, encouraging a state of relaxation and stillness, reducing the impact of chronic stress.
Meditation is another powerful tool that encourages a state of focused attention and awareness. By being an observer of our thoughts, meditation helps to quiet the mind and reduce the constant bombardment of stressors that can trigger a physiological response. Meditators have been shown to exhibit lower circulating cortisol levels, improved autonomic nervous system coherence (HRV), and better emotional stability. Various forms of meditation, including mindfulness meditation, loving-kindness meditation, and body scan meditations, offer different approaches to centering the mind.
All forms of meditation focus on creating space to bring non-judgmental awareness to your body and what it is trying to communicate with you. To practice this, lie flat on your back with your arms at your sides and your eyes closed. Take a few deep breaths until you feel relaxed, feeling the weight of your body grounding you. Allow your attention to roam freely over any sensations you notice—tension, restriction, or discomfort in different parts of your body. When your attention is drawn to a specific area, pause there and invite the sensation with curiosity. Is there an emotion attached to it? Identify the emotion and ask your body for permission to feel it. Take deep, easy breaths and let your attention soothe the area. If you fall asleep during this practice, it’s a sign of stress relief and is perfectly normal.
Breathing exercises, such as diaphragmatic breathing, box breathing, and alternate nostril breathing, are simple yet effective techniques for reducing perceived stress and improving HRV. The breath is a direct link to our autonomic nervous system. By consciously controlling the pace of our inhalations and exhalations, we can instantly lower heart rate and blood pressure, promoting a sense of calm.
One innovative tool that leverages neuroscience technology to enhance relaxation and mental well-being is NuCalm. This app uses a combination of audio therapy and neurofeedback to help reduce stress and promote a sense of calm. NuCalm’s audio therapy involves listening to specially designed tracks that use binaural beats and other sound frequencies to guide the brain into a deep state of relaxation. Neurofeedback monitors and optimizes brainwave activity, retraining the brain for improved self-regulation and enhanced plasticity.
Consistent incorporation of mind-body practices and utilizing tools like NuCalm into your daily routine can lead to lasting benefits for HRV and overall well-being. These practices help create better autonomic nervous system regulation, counterbalancing the effects of stress and promoting recovery.
The Connection Between Stress and Metabolic Health
As you have learned, stress management is crucial for maintaining regulated blood sugar levels and overall metabolic and hormonal health. As previously mentioned, when the body is under stress, it releases hormones like cortisol and adrenaline, which can raise blood sugar levels. This response is part of the body’s natural “fight or flight” mechanism, designed to provide a quick energy boost in times of need. However, chronic stress can lead to prolonged elevation of these hormones, contributing to insulin resistance, making it harder for cells to absorb glucose effectively, and increasing the risk of developing conditions like type 2 diabetes and polycystic ovarian syndrome (PCOS).
PCOS, at large, is a manifestation of insulin resistance in the ovarian theca cells. Insulin can influence theca cell function, including the production of androgens, which are precursors to estrogens.This increased sensitivity and subsequent overproduction of androgens can contribute to the hormonal imbalances seen in PCOS, leading to irregular menstrual periods, excess hair growth, and weight gain. This connection highlights the importance of mindfulness interventions to help mitigate stress and promote better insulin sensitivity and metabolic health.
To support metabolic health, maintaining balanced blood sugar levels is paramount, and dietary modifications play a crucial role in this. A balanced diet rich in whole foods, fiber, healthy fats, and lean proteins is essential for regulating blood sugar levels and managing body weight. It is important to minimize the intake of highly processed foods, excessive sugar, particularly sugar-sweetened beverages, and unhealthy/inflammatory fats, as these can contribute to inflammation and insulin resistance. Check out our more detailed blog post on diet and lifestyle interventions for metabolic health here.
Regular physical activity is also critical for managing blood sugar levels as it increases glucose uptake by muscles, improves insulin sensitivity, and helps prevent insulin resistance. Activities such as resistance weight training not only aid in weight management but also help tone and build muscle, which acts as a glucose disposal sink. For individuals with diabetes and PCOS, regular physical activity is essential for blood sugar control. Beyond glucose metabolism, exercise also improves cardiovascular health, enhances mood, and reduces the risk of many chronic diseases and cancers.
Quality supplementation can be supportive in maintaining healthy blood sugar levels, especially when combined with diet and lifestyle interventions. Certain supplements, like berberine, inositol, and bitter melon, have been studied for their potential benefits in improving insulin sensitivity and glucose metabolism. You will find my favorite supplements in my Metabolic Support Protocol that I use to optimize blood sugar and metabolic health. As always, individuals should consult with a healthcare professional before starting any new supplement regimen, especially if you are already on blood sugar lowering medications.
