When it comes to managing PCOS, many people immediately think of food and exercise. But if I had to choose one thing to focus on, it would be managing stress. Every. Single. Time.
Because stress has a direct impact on your hormones, and for women with PCOS, learning to manage stress can be an absolute game-changer.
Our nervous system has two key components: the
Sympathetic Nervous System (SNS), which triggers the “fight or flight” response, and the
Parasympathetic Nervous System (PNS), which governs “rest, digest, repair, and detox.” Under normal circumstances, these systems work in harmony, taking turns to keep us balanced. However, when we're constantly in stress mode—living that go-go-go, busy-as-a-badge-of-honor lifestyle—the SNS takes over. This keeps us stuck in survival mode, with stress hormones like cortisol and adrenaline flooding our system.
For women with PCOS, this is particularly concerning. Imagine your body is facing a life-threatening situation, like encountering a wild tiger. All your energy is diverted into survival mode—sending resources to your muscles so you can fight, run, or flee. Digestion, reproduction, and your monthly cycle? Not a priority. Your body literally shuts down these functions because it's not the right time to make babies or digest food when you're fighting for survival.
In today’s world, we’re not typically facing wild tigers. But rushing to meetings, over-scheduling, and constant demands? Your body doesn’t know the difference. It still reacts as though it’s in danger, keeping you in survival mode. As a result, reproductive and digestive health take a backseat.
Cortisol and Insulin Resistance
Chronic stress elevates cortisol levels (source), which can contribute to insulin resistance—a major concern for women with PCOS. Research shows a direct link between high cortisol and insulin resistance in PCOS patients. When insulin levels rise, they stimulate an increase in androgens, which can trigger symptoms like acne, hair thinning, and hirsutism (unwanted hair growth).
Hormone Disruption and Irregular Cycles
Stress also disrupts the
Hypothalamic-Pituitary-Adrenal (HPA) axis, which plays a key role in regulating hormones. When the HPA axis is out of balance, it can lead to irregular cycles or even missed ovulation (source). If your body perceives constant stress or danger, it prioritizes survival over reproduction, effectively shutting down reproductive functions. Studies have shown that HPA axis dysregulation can lead to hormonal imbalances that interfere with reproductive health.
While nourishing your body and moving are essential, managing stress is often the most powerful factor in balancing PCOS. A balanced nervous system leads to balanced hormones, and when your body feels safe, it can thrive—not just survive.
Small, consistent changes like mindful movement, eating the right foods, and getting quality sleep – help create a calmer internal environment, making it easier to manage PCOS. Your body is resilient. Give it the tools to relax and rest and it will work for you, not against you.
