#205 Stop Nighttime Peeing

Dec 25, 2025

Delve into the world of nocturia, a common sleep disruptor, as the host explores its root causes like sleep apnea and enlarged prostate. Learn about the important roles of hormones in nighttime urination. Discover practical behavioral modifications, from fluid timing to bladder training, that can help reduce nighttime trips. The discussion also covers helpful supplements like pumpkin seed extract and beta-sitosterol, along with pharmaceutical options such as Desmopressin and alpha-blockers, ensuring a comprehensive approach to tackling this issue.

INSIGHT

Nocturia Is Mechanistically Diverse

Nocturia means waking to urinate more than twice per night and often harms sleep quality.
Different mechanisms (volume, bladder signal, sleep-driven) can coexist and require different treatments.

INSIGHT

Heart Hormones Link Sleep Apnea To Nighttime Peeing

ANP released when the heart stretches suppresses ADH and increases nighttime urine.
This explains why sleep apnea (airway collapse → negative intrathoracic pressure → atrial stretch) causes nocturia unrelated to bladder health.

ADVICE

Fix Sleep Apnea With CPAP

Treat sleep apnea to stop the ANP–ADH cascade; CPAP is the highest-evidence treatment.
Use CPAP to prevent airway collapse and subsequent atrial stretch that drives nocturia.

In this solo episode, Dr. Mike discusses the common issue of nocturia, where individuals frequently wake up at night to urinate, which disrupts sleep. The episode covers the root causes including sleep apnea, enlarged prostate, and overactive bladder, and dives into the roles of antidiuretic hormone (ADH) and atrial natriuretic peptide (ANP). It provides a comprehensive guide on addressing nocturia through behavioral modifications such as fluid restriction and sleep hygiene, supplements like pumpkin seed extract and beta-sitosterol, and pharmaceuticals including Desmopressin and alpha-blockers. The host also touches on treating sleep apnea with CPAP machines and mandibular advancement devices, emphasizing the importance of targeting the root cause for effective treatment.

The Hart2Heart podcast is hosted by family physician Dr. Michael Hart, who is dedicated to

cutting through the noise and uncovering the most effective strategies for optimizing health,

longevity, and peak performance. This podcast dives deep into evidence-based approaches to

hormone balance, peptides, sleep optimization, nutrition, psychedelics, supplements, exercise

protocols, leveraging sunlight light, and de-prescribing pharmaceuticals—using medications only when absolutely necessary.

Beyond health science, we tackle the intersection of public health and politics, exposing how

policy decisions shape our health landscape and what actionable steps people can take to reclaim control over their well-being.

Guests range from out-of-the-box thinking physicians such as Dr. Casey Means (author of "Good Energy") and Dr. Roger Sehult (Medcram lectures) to public health experts such as Dr. Jay Bhattacharya (Director of the National Institutes of Health (NIH) and Dr. Marty Mckary

(Commissioner of the Food and Drug Administration (FDA) and high-profile names such as

Zuby and Mark Sisson (Primal Blueprint and Primal Kitchen).

If you're ready to take control of your health and performance, this is the podcast for you. We cut through the jargon and deliver practical, no-BS advice that you can implement in your daily life, empowering you to make positive changes for your well-being.
