INSIGHT

Work With 90-Minute Brain Cycles

Our brains run on 90-minute ultradian cycles that drive peaks of focus and dips of recovery.
Working with these rhythms (deep work in peaks, breaks in dips) boosts productivity and preserves energy.

ADVICE

Block A Morning Deep Work Slot

Schedule one 90-minute deep work session about 90 minutes after waking to use your peak focus.
Protect that block for cognitively hard tasks rather than shallow busywork like email.

ADVICE

Take Real Screen-Free Micro Breaks

Take micro recovery breaks that avoid screens and look far into the distance to activate restorative brain networks.
Walk outside when possible to combine distant focus, movement, and fresh air for a real reset.

If all you want to do by 3 PM is nap... this one’s for you. I share 5 powerful, science-backed hacks I personally use to feel more energized and clear-headed, fast. You won’t hear “get more sleep” or “cut sugar”. These are unique, practical tools you can use today.

I’ll walk you through everything from how your brain’s ultradian rhythm impacts focus and fatigue, to the truth about why most of us don’t get impactful rest during our breaks (and how to fix it). You’ll learn how to close mental loops draining your energy, why peppermint tea works better than a third cup of coffee, and how a simple dose of sunlight can recharge your battery, resetting your entire day.

🎧What you’ll learn:

The 90-minute brain rhythm that boosts productivity and prevents burnout
How to get the quickest re-charge during a break
Why unfinished tasks drain your brain—and how to shut the loop
My favorite natural energy drink
The light hack I swear by to feel more awake, focused, and stable

✨Homework: Schedule in one, 10-minute break to step outside or look far into the distance, and take 2 minutes of this time to exhale longer than you inhale (no phone, no scrolling, no multitasking). Notice how you feel after.
