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 — the kind that illuminates from without and the kind that radiates from within. It’s for those who feel called to live in alignment with what heals, what reveals, and what nourishes. We gather here to remember that wisdom is cyclical, rest is sacred, and care can be radiant — for ourselves, our families, and the wider world.
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.

“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?”
