Stress is often called "the silent killer" because of its stealthy and mysterious effects on everything from heart disease to mental health. Now National Science Foundation-funded researchers have developed a new test that can easily and simply measure common stress hormones using sweat, blood, urine or saliva. Eventually, they hope to turn their ideas into a simple device that patients can use at home to monitor their health. The researchers developed a device that uses ultraviolet light to measure stress hormones in a drop of blood, sweat, urine or saliva. These stress biomarkers are found in all of these fluids, albeit in different quantities. The device measures not just one biomarker but multiple biomarkers. And it can be applied to different bodily fluids.
