It’s not as if any period in human history was particularly gentle, but we do seem to live in very stressful times. Maybe it’s not the stress that’s changed, but that we’re more able than ever to notice, monitor and analyze what’s going on in our bodies. Here at CES 2025, startup Eli Health is launching Hormometer, an at-home kit that tests your cortisol and progesterone levels.

Hormometer is a wand with a collection tip at one end that you hold in your mouth for 60 seconds. Once it’s absorbed your spit, you’ll sit it down on a table for 20 minutes while the cartridge’s network of built-in microfluidics gets to work. After that, the assay will start displaying lines in a specific color, which can be read and interpreted by your smartphone camera.

The app will then be able to, presumably once it’s established your individual baseline levels, offer helpful suggestions for how to better manage your health. It’s likely those will get more detailed over time, as Eli Health says it’s creating the first data set of its kind. Which, if you’re unaware, means your hormone levels are likely going into a very large database with all of its users. The company will have to answer many questions about how it’s planning to protect the privacy of its users, especially in the US.
