As we enter 2026, millions are embracing Dry January, a month-long break from alcohol that originated in the UK in 2013 and has since become a global phenomenon. While many participate for clearer skin, better sleep, or weight loss, the deeper benefits for hormonal health are profound and long-lasting. At Glow Health and Wellness, we specialize in functional medicine and bioidentical hormone replacement therapy (BHRT), and we frequently guide clients through lifestyle changes like reducing alcohol to restore natural balance.
Alcohol, even in moderate amounts, disrupts key hormones including cortisol, insulin, estrogen, progesterone, and testosterone¹. Chronic or heavy consumption burdens the liver, alters metabolic pathways, and interferes with the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-adrenal (HPA) axes². Taking a break, whether for January or longer, allows your body to recalibrate, often leading to improved energy, mood stability, sleep quality, and reproductive health.
This comprehensive guide explores the science behind alcohol's hormonal impacts, the specific benefits of going dry, practical strategies for success, and how these changes can support year-round wellness.
Alcohol is metabolized primarily in the liver, where it competes with hormone processing. This leads to imbalances that affect nearly every system in the body.
Alcohol acts as a central nervous system depressant initially but ultimately elevates cortisol, the primary stress hormone³. Acute intake disrupts sleep architecture, reducing REM sleep and causing rebound cortisol spikes the next day⁴. Chronic consumption dysregulates the HPA axis, leading to persistently high cortisol levels that contribute to anxiety, weight gain (especially abdominal fat), and adrenal fatigue.
Studies show that even moderate drinking increases cortisol secretion, exacerbating stress-related disorders⁵. Abstaining normalizes these rhythms, promoting resilience and better emotional regulation.
Alcohol impairs glucose metabolism by inhibiting gluconeogenesis and promoting insulin resistance⁶. Sugary mixers and beer exacerbate spikes, while the liver prioritizes alcohol detoxification over blood sugar regulation. This cycle can worsen PCOS symptoms, contribute to metabolic syndrome, and increase diabetes risk⁷.
Reducing alcohol improves insulin sensitivity within weeks, stabilizing energy levels and reducing inflammation that indirectly affects sex hormones.
Alcohol significantly alters reproductive hormones. In women, it increases estrogen levels by impairing liver clearance and enhancing aromatization of androgens⁸. This can lead to estrogen dominance, manifesting as PMS, heavy periods, fibroids, or heightened menopausal symptoms⁹. Progesterone often decreases, disrupting ovulation and fertility¹⁰.
In men, alcohol suppresses testosterone production via direct testicular toxicity and elevated estrogen¹¹. Chronic use is linked to reduced libido, erectile dysfunction, and infertility¹².
Postmenopausal women may see temporary estradiol spikes, potentially influencing hormone therapy efficacy¹³. Overall, alcohol disrupts the HPG axis, affecting LH, FSH, and gonadotropin-releasing hormone¹⁴.
The liver detoxifies excess hormones, particularly estrogen. Alcohol overloads phase I and II detoxification pathways, leading to buildup of harmful metabolites¹⁵. Cruciferous vegetables support these pathways naturally, but alcohol hinders their efficiency.
Alcohol interferes with thyroid hormone conversion (T4 to active T3) and can induce hypothyroidism-like states¹⁶. It also affects growth hormone and prolactin, influencing metabolism and mood.
The positive changes often unfold in phases:
Week 1–2: Better sleep quality as alcohol’s sedative-rebound effect fades. Lower morning cortisol, reduced bloating, clearer thinking, and improved hydration status.
Week 3–4: Noticeable stabilization of blood sugar and energy. Mood lifts as serotonin and GABA systems recover. Liver enzymes begin normalizing, and estrogen metabolism improves.
Beyond January: Sustained participants frequently report regular menstrual cycles, fewer PMS symptoms, reduced hot flashes, higher libido, easier weight management, and greater emotional resilience. Many find these improvements so significant that they choose to maintain low or no alcohol intake long-term.
Success isn’t about willpower alone—it’s about creating an environment and routines that make abstaining feel natural and enjoyable.

These options feel celebratory rather than restrictive.
Many participants find Dry January so rewarding that they naturally shift toward mindful or minimal drinking afterward. Others adopt a “damp” approach with occasional, intentional consumption in small amounts.
At Glow Health and Wellness, we encourage clients to use this month as a diagnostic tool: pay close attention to how your body responds without alcohol. If symptoms like fatigue, irregular cycles, mood swings, low libido, or stubborn weight dramatically improve, it may indicate that ongoing reduction would serve you well.
For those with persistent imbalances despite lifestyle optimization, we offer comprehensive hormone testing, nutritional guidance, and personalized BHRT to restore equilibrium at the root level.
Dry January is far more than a temporary cleanse—it’s an empowering opportunity to experience your body’s natural state of balance. By giving your hormones a break from alcohol’s disruptive effects, you create space for deeper sleep, stable energy, emotional resilience, and vibrant reproductive health.
Whether you choose complete abstinence or conscious moderation moving forward, the insights gained this month can profoundly shape your wellness journey throughout 2026 and beyond.
Here’s to a clear-headed, balanced, and energized new year. Cheers—with sparkling water, herbal tea, or your favorite mocktail!
