The Winter Light Diet: How to Fix Your Rhythms and Thrive in the Cold | Heidi Sime

<p>Sarah Kleiner welcomes Heidi Sime, CEO of DreamWalkers, to discuss circadian living—especially through fall and winter in northern Wisconsin where extreme cold and short days make light management critical. Heidi shares her health journey, relationships, and how her husband Thaddeus Owen (a circadian rhythm expert who improved insomnia and anxiety with blue light blockers and gave a TEDx talk) introduced her to red evening lighting and consistent post-sunset blue light blocking. They emphasize non-negotiable morning sunlight even in winter, banking summer sun exposure, and consider winter strategies such as travel south, UVB lamps, and carefully chosen tanning/solarium options. Heidi describes seasonal internal practices like three months of morning journaling rituals, and seasonal eating shifts including ketogenic or carnivore phases. The conversation also touches on parenting, reducing screen reliance, avoiding rigid health dogma, and Heidi’s women-focused blue light glasses, Morning Light Club hat, and related products.</p><p><br /></p><p>— </p><p>Connect with Heidi </p><p><a href="https://dreamwalkerz.ai/discount/SarahK" target="_blank" rel="ugc noopener noreferrer">https://dreamwalkerz.ai/discount/SarahK</a> </p><p><a href="https://www.instagram.com/heidisime_/?hl=en" target="_blank" rel="ugc noopener noreferrer">https://www.instagram.com/heidisime_/?hl=en</a> </p><p><br /></p><p>_________ </p><p>Sponsored By:</p><p>→ Kēpos | For a limited time, you can get 47% off your first order, PLUS free gifts valued at $62.
