The Stress Thermometer lets you see changes in your hand temperature, which is a reflection of your blood flow and a measure of your stress response. When you’re stressed, tiny blood vessels under your skin constrict, and the flow of blood is redirected to your major muscles and internal organs. This is why your hands feel cold when you are under stress. The blood has been rushed away from your fingers, to the more vital parts of your body because of the fight-or-flight response. Hand temperatures can range greatly, from a low of 60° to as high as 99° F. When you’re stressed, 5° changes can take place in seconds. The basic rule for interpreting your temperature change is simple, "Cold hands are tense, warm hands are relaxed." Your temperature is connected to your stress level. When you are tense, the blood circulation in your hands and feet is reduced. This reduced circulation causes a drop in temperature. Relaxing increases your peripheral blood circulation, warming your hands and feet. With simple stress reduction exercises, you can increase your blood flow, raising your temperature. The Stress Thermometer lets you gauge your baseline temperature and stress level, and see moment-to-moment skin temperature changes as they relate to your stress level. Breathing from your lower diaphragm and not your upper lungs, inhale fully through your nose. Hold your breath for a moment, and exhale slowly through your mouth. Repeat, ing for 6-12 breaths per minute. Watch your temperature increase as you relax. Measures temperature 58°-150°F (≈14°-65°C). Reads in increments of 0.1°.
