Could retraining your body's hormonal system be the key to unlocking improved fertility, weight management, and overall well-being? In this episode, host Meredith Oke and Sarah Kleiner, a quantum health practitioner, explore this intriguing possibility. Sarah shares her journey from personal health challenges to founding a coaching business dedicated to hormonal energy management, transforming her struggles into a path of healing and empowerment.   Sarah emphasizes the importance of leptin as a master circadian signaling hormone, affecting everything from thyroid function and sex hormones to insulin signaling and immune system function. She brings attention to the scarcity of discussion around leptin in mainstream health circles, encouraging listeners to explore its role in common conditions like PCOS and hot flashes.   The conversation also touches on the essential practice of healthy light habits. Sarah shares her own experiences in implementing these changes, particularly avoiding blue light after sunset, to bolster melatonin production, which significantly improved her fertility and overall health.   Sarah's story, from overcoming personal health issues to building a successful wellness practice, serves as a testament to the transformative power of understanding and managing the body's hormonal system.   If you're interested in learning more about quantum biology and incorporating these principles into your own life or wellness business, be sure to check out Sarah's podcasts, Evolving Wellness and Quantum Conversations, and explore the resources available at QuantumBiologyCollective.org.   Quotes: “Leptin is a master circadian signaling hormone that really impacts thyroid, sex hormones, signals insulin, your immune system, your heart. I mean, it's a key hormone that often gets ignored and people say it's your satiety hormone and they kind of just look at it as this hunger satiety thing and they don't actually see all the other implications.” (12:15 | Sarah Kleiner)  “Darkness is healing. We need darkness, like we require darkness in the same way that we require light and food - it is a foundational requirement for the health of our bodies.” (34:13 | Meredith Oke)  “The more that you become connected to those light dark cycles, as well as cold cycles and heat cycles, you know, the natural cycles of nature, the more you're able to tap into that inner knowing, that inner voice, your intuition, and say no to things or know that something isn't right for you.” (40:23 | Sarah Kleiner)    Links Connect with Sarah Kleiner: Website: https://www.sarahkleinerwellness.com Instagram: @sarahkleinerwellness Podcast: https://podcasts.apple.com/us/podcast/the-evolving-wellness-podcast-with-sarah-kleiner-wellness/id1550150550 Podcast: https://podcasts.apple.com/us/podcast/quantum-conversations/id1697538368   To find a practitioner who understand the health principles of quantum biology: www.quantumbiologycollective.org    To become a QBC member and get invites to live deep dives & access to our video library: www.quantumhealthtv.com    To take our 8 week practitioner certification in the science of quantum biology so that you can add it to your existing area of expertise: www.appliedquantumbiology.com    Follow on Twitter, Instagram & Facebook: @quantumhealthtv    Podcast production and show notes provided by HiveCast.fm
