How to Control Your Cortisol & Overcome Burnout

About this video

Huberman reframes cortisol as a hormone that deploys and directs energy to tissues that need it, not simply a stress hormone. He says the central rule is rhythm: cortisol should be high early in the day, shortly after waking, and low in the hours before sleep and during early sleep. Huberman links a flattened or shifted rhythm to the wired-and-tired pattern of burnout, low morning energy, and nighttime insomnia or morning anxiety, and argues fixing the rhythm can largely resolve those patterns. He describes cortisol as a wave you can amplify early using light, hydration, caffeine, and exercise. On foods, Huberman says grapefruit inhibits the enzyme CYP3A4 that breaks down cortisol, extending cortisol’s life in the bloodstream by 25 to 50 percent in human studies he cites, which is why people instructed to elevate cortisol medically are told to avoid it.
