Description
Anxiety was originated in 1520's from the Latin word anxietatem (anxieties) meaning anguish, anxiety and solicitude; is when a person is an unpleasant state of mind and is feeling fear, worry and uneasiness. It’s a normal human emotion, which everyone can say they had experience at times, and they will go through great lengths to avoid it. Anxiety can be related to anything that can be triggered by stress, and also can interfere with a person ability to function with their daily life.

Electromyograph- Is a device that you put on your finger or thumb. The process of it is to check your skin temperature.
Feedback Thermomter- It can be attached to your finger or thumb, that senses your body skin temperature. From there it measures the expansion and contraction of your blood vessels.
