Morning

Cortisol peaks after waking, priming your body for the day ahead. On low energy mornings, this window is worth checking.

Evening

By night, cortisol should drop. Test before bedtime to learn if cortisol is staying high, impeding sleep and recovery.

Easy to use tests and I exported the data and shared with my doctor as a part of my health care plan.

I found it super helpful to be able to mesure salivary free cortisol on my own, since my doctor’s test only measures one day and I’ve wanted to see what my cortisol looks like with different activities, symptoms, and times.
