How do Stressdots™ work?
When you are stressed there is an increase in muscle tension, the blood vessels near the skins surface constrict and the temperature of your hands and feet decreases. Similarly as you relax, your hands and feet become warmer as the blood flows more freely. The colour changes of the Stressdot™ simply and graphically demonstrate the changes in the body’s stress levels.
