Your body's natural rhythm, decoded.

Your cortisol should follow a diurnal curve, peaking in the morning to give you energy and tapering toward bedtime to support recovery.  When levels peak and dip at the wrong times—or stay elevated due to chronic stress—your body can’t perform optimally.

07:08 AM

Wake up energized,
not exhausted.

A healthy morning cortisol surge powers your energy, focus, and mood for the day ahead. If your levels don’t follow the optimal curve, you’re probably hitting snooze.

11:48 AM

Train smarter.
Recover faster.

Cortisol rises during intense exercise. Testing after exertion shows whether you're recovering properly or pushing toward burnout.

03:28 PM

See stress as it happens.

Spot-check after a tough meeting, flight delay, or argument to see exactly how your body responds—and what’s helping you bounce back.

09:58 PM

Finally wind down for
deep sleep.

Cortisol should hit its lowest point before bed. An evening reading reveals if late screens, snacks, or racing thoughts are keeping you wired.

“Cortisol shapes how our bodies respond to stress, impacting sleep, immunity, metabolism, performance, and recovery. Gaining insight into its patterns is key to optimizing long-term health and well-being.”

Cortisol: the stress hormone

Understanding cortisol:  
the hormonal powerhouse.

Regular tracking reveals hidden imbalances, so can resolve issues before they become real problems—not just manage symptoms.

It's not just about stress. Cortisol orchestrates your entire day.

Think of cortisol as the backstage manager of your body's daily performance. It doesn't just spike during stress—it actively regulates:

ENERGY LEVELS
SLEEP QUALITY
EXCERCISE RECOVERY
IMMUNITY AND HEALING
METABOLISM
EMOTIONAL BALANCE

What disrupts your cortisol rhythm?

Symptoms like fatigue, poor sleep, brain fog, energy crashes, metabolic issues, or low immunity often trace back to cortisol imbalances.

Five daily habits that disrupt your optimal curve ↓

Behavior	Cortisol Symptom	Intervention
Work overload + worry	Chronically elevated → wired but exhausted	3×30-sec box breaths
Screens before bed	High at night, low in morning → poor sleep + fatigue	Phone-free after 9 pm
Sleep debt	Delayed morning peak, elevated → poor alertness	Aim for 7-9 hrs, same wake time
Over-training	Chronically elevated → burnout + fatigue	Add a rest or lower-intensity day
Caffeine + alcohol	Irregular spikes → disrupted rhythm	Cut coffee at 2 pm, 2-drink max

Over time, these create a cycle where you're exhausted but can't rest, hungry but can't satisfy your appetite, motivated but can't focus
