If you have polycystic ovary syndrome, you already know that hormones can feel like a constant balancing act. Androgens—often thought of as “male” hormones—are naturally present in all women, but in PCOS they tend to run high. This can drive stubborn symptoms like cystic acne, thinning scalp hair, excess facial or body hair, and irregular periods. While medication and genetics play a role, certain everyday choices can quietly push those androgen numbers even higher. The good news: recognizing two of the most common missteps can give you a real edge in managing your levels.
Mistake #1: Skimping on quality sleep—or sleeping at the wrong times
Sleep and hormones have a powerful two-way relationship, and it’s often overlooked in PCOS management. When you don’t get enough deep, restorative sleep—or when your sleep schedule is erratic—your body’s stress response kicks in. This triggers a rise in cortisol, the primary stress hormone. Cortisol and androgens are produced from the same precursor molecules (pregnenolone and 17-hydroxyprogesterone), so when cortisol demand goes up, the pathway can shunt into excess androgen production.
In one study published in the Journal of Clinical Endocrinology & Metabolism, women with PCOS who reported poor sleep quality had significantly higher levels of total testosterone and free androgen index compared to those who slept well, even after adjusting for body mass index. The effect was most pronounced in women who also had high stress scores.
But it’s not just about how many hours you log. The timing matters, too. Shift work, staying up past midnight regularly, or inconsistent bedtimes confuse your circadian rhythm. This disruption can lower melatonin (which normally helps dampen cortisol at night) and further fuel the adrenal-androgen pathway. For many women, a simple shift—aiming for a consistent 7–9 hours with a wind-down routine that starts before 11 p.m.—can lead to noticeable improvements in both energy and skin clarity within a few weeks.
A quick caveat: If you struggle with insomnia or sleep apnea (common in PCOS), talk to a sleep specialist. Improving sleep hygiene is a good first step, but underlying conditions need proper evaluation.
Mistake #2: Over-relying on high-sugar, high-glycemic carbs without enough protein or fiber
The connection between blood sugar and androgens is one of the most well-documented mechanisms in PCOS. When you eat a meal or snack that’s heavy in refined carbohydrates—think white bread, sugary cereal, instant rice, or sweetened drinks—your blood sugar spikes. In response, your pancreas releases a surge of insulin to bring that sugar down. In PCOS, many women already have some degree of insulin resistance, meaning their cells don’t respond well to insulin. The body compensates by pumping out even more insulin.
High circulating insulin directly stimulates the ovaries to produce more androgens. It also suppresses sex hormone-binding globulin (SHBG), the protein that normally mops up free testosterone in the bloodstream. Lower SHBG means more unbound, active testosterone floating around, which worsens PCOS symptoms.
This doesn’t mean you need to go zero-carb or adopt a strict keto diet—extreme restriction can backfire by increasing cortisol. The smarter approach is to pair any carb-rich food with a source of protein (eggs, Greek yogurt, tofu, chicken, legumes) and fiber (vegetables, chia seeds, nuts). Protein and fiber slow digestion, blunting the insulin spike. For instance, swapping a plain bagel for a half-bagel with smoked salmon and avocado, or adding a handful of almonds to an apple, can make a measurable difference.
One 2019 randomized trial in Nutrients found that women with PCOS who followed a moderate-carb, higher-protein diet (30% protein, 40% carbs, 30% fat) for 12 weeks had significantly lower free testosterone and higher SHBG compared to those on a standard low-fat diet, even though total calorie intake was similar.
Putting it together: small shifts, real impact
These two mistakes might seem basic, but they’re the ones that come up over and over in clinical conversations—and they’re also the most actionable. You don’t need a prescription to start sleeping more consistently or to upgrade your snack choices. Over time, addressing both can lower the background noise of high androgens, potentially reducing the need for higher doses of medications or more aggressive interventions.
Of course, this is part of a bigger picture. Stress management, regular movement (especially resistance training and walking), and a nutrient-dense diet with plenty of anti-inflammatory fats (think omega-3s from fish or flax) also support healthy androgen levels. But if you’re feeling overwhelmed, starting with these two areas—sleep and blood sugar balance—gives you a clear, evidence-based entry point.
And remember: every body responds differently. If you’re already taking medication like spironolactone, metformin, or an oral contraceptive, don’t stop or change anything without talking to your healthcare provider. These lifestyle adjustments work best as a complement, not a replacement, for medical care.
