BIODOT® - an aid to relaxation and managing stress

Biodot® Skin Thermometers are small self-adhesive, temperature sensitive discs that are placed on the skin to monitor the skin temperature. Changes in skin temperature are due to changes in the amount of blood flowing through the skin. More blood flow - the skin is warmer; less blood flow - the skin is cooler.

When a person is tense the skin blood vessels constrict, reducing the blood flow; the Biodot will appear yellow, amber or black. When a person is calm and relaxed the skin blood vessels dilate, increasing blood flow; the Biodot will appear turquoise, blue or violet. A colour interpretation chart is used to relate the colour of the Biodot to the level of relaxation and tension.

Biodots are particularly useful in biofeedback during relaxation training and for motivating and providing reassurance to the user that they are achieving relaxation and tension reduction.
