What if the key to peak performance isn't working harder, but working with your biology instead of against it?

Andrew Huberman's 90-minute focus protocol isn't just another productivity hack. It's based on how your nervous system actually operates, and Nina breaks down the surprising science that makes it work.

What you'll discover:

• Why getting sunlight in your eyes within an hour of waking creates a natural energy boost that lasts all day

• The exact breathing pattern (4-7-8) that switches your brain from stress mode to focus mode in under two minutes

• How 11 minutes of cold exposure per week increases your dopamine by 250% and why timing matters more than temperature

• The evening light trick that optimizes melatonin production without any supplements

This isn't about forcing yourself into someone else's routine. Nina explains which parts of Huberman's protocol actually have solid research behind them and how to adapt them for real life. She's treated enough patients running on caffeine and willpower to know what sustainable energy actually looks like.

You'll learn why your afternoon crash happens at the same time every day, how to use your natural cortisol rhythm instead of fighting it, and which "wellness" trends are backed by actual neuroscience.
