What it's worth.
A single 4-point saliva cortisol panel at a lab costs $170–$440, and it only shows you one day. LumeCoach gives you four, one every week, plus 1-on-1 coaching and a wearable, for $995. That's about $36 a day for 4 weeks. Ask yourself what it's worth to stop guessing why your energy crashes.

LumeCoach questions, answered.
Cortisol is your body's main stress hormone, but it also plays an important role in your circadian health. It shapes your energy, focus, sleep, and mood throughout the day. When its rhythm is off, you can feel “flat" or “off” because your body's chemistry is out of balance.
Hours aren't the whole story. Cortisol should rise in the morning and fall at night. When that pattern shifts, sleep doesn't restore our energy in the same way.
Yes. Elevated cortisol changes how your body regulates appetite, stores fat, and metabolizes glucose. That's partly why it can feel that your weight is stuck when you are doing all the right things.
Struggling to wake up. Waking at 3am and not getting back to sleep. Feeling "tired but wired." Afternoon energy crashes. Weight that won't budge. Or just not feeling like yourself. Everyone's pattern is different, which is why seeing your own matters.
Your circadian rhythm is your body's internal ~24-hour clock. It governs many of your body's processes including when hormones like cortisol rise and fall, sleep, energy, and metabolism, which is why tracking it can reveal so much about why your days feel the way they do.
No. Most wearables estimate "stress" from heart rate and compare you with population averages. Lume is built around cortisol itself, and a few of your own saliva samples calibrate it, so what you see is your rhythm, not an average. It adds to the wearable you already have instead of replacing it. Next, we're building toward reading cortisol directly from sweat, the same direct approach a continuous glucose monitor takes, without the needle.
Yes, and the field is moving fast. Sweat carries hormones like cortisol, and research groups, including scientists on our team, have built sensors that detect them without blood draws or lab visits. Lume's first product estimates your cortisol rhythm from wearable signals, calibrated to gold standard cortisol measurement from your saliva samples, while our lab develops sensors that read cortisol directly from sweat.
A typical blood or saliva test gives you one data point. Lume shows the pattern: how cortisol moves across your whole day, not a single reading. And that's where most of the important information lives.
