How does understanding your brain's ultradian rhythms help you structure your most productive skincare formulation sessions?

Title: How Can Ultradian Rhythms Optimize Skincare Formulation Sessions?

Lately, I’ve been curious about how our brain’s natural energy cycles those 90-minute ultradian rhythms might impact focused work like skincare formulation. I’ve noticed my focus tends to ebb and flow, and I’m wondering if anyone else has experimented with timing their creative or technical sessions around these cycles.

Do you structure your formulation work in shorter, intense bursts to align with peak focus? Or have you found ways to leverage the natural downturns for less demanding tasks, like research or note-taking? I’d love to hear how others balance productivity with their brain’s natural rhythm, especially in such a detail-oriented field. Any tips or personal experiences to share?
