How to improve your family's circadian rhythms

An evidence-based protocol for stabilizing and strengthening circadian rhythms and optimizing wellbeing at all ages, beginning in the womb

I created this protocol as part of my certification process through the Quantum Biology Collective.

I encourage you to take their course if at all interested in applying this circadian material professionally! Here’s where you can learn more:

The following protocol I created sums up everything we have been talking about here at Brighter Days, Darker Nights in one simple list of ideas. For 1-1 support, you can book a complimentary consultation with me here: Virtual Meet & Greet.

Like everything published here, this protocol is for informational purposes only. This information is not intended to diagnose, prevent, or cure any medical condition, nor to replace medical advice offered by qualified health care providers. Any application of the material provided is at your own discretion and is your own, sole responsibility.

For a downloadable and printable version, either become a subscriber for free, or if you are already a subscriber but haven’t downloaded your copy yet, just email me and I’ll send it to you. Here’s the protocol, complete with evidence from peer-reviewed literature.

Protocols for taking care of your family’s circadian rhythms

I know that’s a lot of research, but I thought it was important to share so that you could find more information and evidence about the aspects of the protocol that most relate to you and your family’s unique situation. If you are (or become) a founding member, you are welcome to start a chat with any questions!
