See your body’s response

Your cortisol levels, your daily patterns, and the habits shaping how you feel during hormonal transitions.

Hormonal shifts change how your cortisol curve responds.

Morning

Cortisol peaks after waking to boost energy. If that peak flattens, mornings can feel like wading through mud.

Evening

By night, cortisol should drop. If it doesn’t, you stay awake, feeling tired, wired, and unable to sleep.

The curve tells the real story

A flattened or shifted curve often shows up as fatigue, mood changes, or broken sleep. Eli shows you the full shape of your cortisol curve.

I was curious to check my cortisol levels knowing how much it affects females in their 30s. Glad they're in the range. Eli strips are easy to use, and the app sends you reminders so you don't forget to do the test on time.

I was able to monitor my cortisol and see what affects it. For example overtime, I realized that my mindfulness routine was bringing my cortisol back into range. I also saw how stress or sickness affects my cortisol cycle.
