And isn’t it interesting that even your actual fingerprint itself sweats!? Yes, it’s one way that drug tests are performed.2 Small openings in the ridges that form your fingerprints are actually sweat pores connected to ducts of sweat glands under the skin. The science of poroscopy examines the characteristics of sweat pores on fingerprints to make a personal identification. (So, it’s not just our palms that get sweaty when we’re nervous!)
Isn’t all sweat the same? Well, actually, no it isn’t. Two different sweat glands produce two different kinds of sweat in your body. And, two other types of glands contribute to your unique sweat composition as well. Different conditions trigger different kinds of sweat.
