About 🌞Brighter Days, Darker Nights🌚
This is a bestselling publication on Substack written by doula & perinatal quantum biology practitioner Nikko Kennedy.
This space is held in devotion to the rhythms of light. Light illuminates from without and radiates from within. It’s for those who feel called to live in alignment with light that heals, reveals, and nourishes. I publish to help you re-establish relationship with the aspects of nature that are cyclical, restful, and radiant. Learning and transforming life in this way is for ourselves, our families, and the wider world. We all benefit from better relationships with natural light.
Subscribe to explore circadian & quantum wellness solutions for things like relieving pregnancy symptoms, transmuting childbirth pain, bolstering postpartum care, giving circadian rhythm support for newborn babies, optimizing puberty hormones, increasing fertility, and getting good sleep across the lifespan 🧡
Why subscribe to Brighter Days, Darker Nights?
If you’ve ever wondered what light has to do with your hormones, why some babies just won’t sleep, or how to feel like yourself again after giving birth, this is your invitation into circadian and quantum-informed care through the birthing year and beyond.
Anyone can read the most recent posts for free on the web and in the Substack website and app. You can find my archive here and follow my Substack Notes here (Substack Notes is social media, but only for Substack readers and writers—a thoughtful crowd, for the most part).

“Such a great first lesson! And I really appreciate the recommended reading list! My ah-ahs: the synergistic relationship of melatonin and oxytocin to support an easier labor and the importance of a strong circadian rhythm in even pair bonding and gender differentiation. My question would be so do you feel like this may be playing a role into why there is such a high divorce rates as well as this emergence of gender fluidity because our circadian balance is so skewed?”
