PMR30 Custom Ruler


SKU: PMR30 Category:


We love that this is a ruler, bookmark, AND stress test all in one!  The front has the stress test and measurements in inches and metric.  On the back is a reminder to “Breathe to Relax!” with a belly breathing exercise.  We also talk about the effect of stress on the body.

This is a 6″ Ruler on 1.5 inch x 7 inch 14pt heavy cardstock card with a durable glossy UV coating on both sides. The stress chip on this card indicates a temperature range of 81-91°F.


To use:  Place thumb or finger on black stress chip. Wait 10 seconds.  Remove thumb and note the color. Then look at the chart. The color will indicate your hand temperature.  The stress chip will return to black color within seconds and can be used over and over again.  If your hands are cold, the stress chip will stay black. Touch it to your neck so you can see the stress chip show color change.  Your neck temperature is around 90°F so the stress chip will turn green or blue.  The stress chip changes colors as temperature changes which can be an indicator of stress level. Catching stress before it builds into a headache, stomach ache or other health problem is a great life skill.  Best when used at room temperature ranges of 70-74°F.

How hand temperature relates to stress.  The basic rule for interpreting temperature change is simple: “Warm hands are relaxed, Cold hands are tense.” Under stress muscles tense and blood flow is restricted to the main body and shut down from the hands and feet.

When the body’s fight or flight system is activated the muscles tense, heart rate speeds up and blood flow is redirected from the extremities to the muscles, heart and vital organs. As a result finger temperature can show changes of 5 degrees or more in seconds as you prepare to fight or flee a dangerous situation.  Our bodies perceive everyday stressors (traffic, deadlines, money, etc.) as an emergency flight or fight event.  The amount of temperature change depends on the stressor or problem and how you react to it.
