Temperature Biofeedback for home use

The Stress Thermometer shows precisely how your thoughts and feelings affect your body by measuring skin surface temperature.


Within seconds, your hand temperature can rise or plummet, reflecting your psychological changes. You can watch how anger, fear, worry, sadness, taxes, divorce, job loss, joy and other factors affect your body. Stress test yourself and friends.

You can use the Stress Thermometer to learn to increase your hand temperature. As your temperature increases, your thoughts and feelings shift to being calmer and more peaceful. Master your body and you will master your mind.

The basic rule for interpreting your temperature change is simple, "Cold hands are tense, warm hands are relaxed."



  • Measures temperature 58°-150°F (≈14°-65°C)

  • Reads in increments of 0.1°

  • Updates temperature display every 2 seconds

  • Switch between Fahrenheit and Celsius

  • 3/4" high LCD display

  • Clock and room temperature feature

Understanding Temperature

There is no „normal‟ temperature, but a range over which temperature fluctuates and changes.

  • High tension - below 79 degrees

  • Slight tension - 79 – 84 degrees

  • Mild/calm - 84 – 90 degrees

  • Quietly relaxed - 90 – 95 degrees

  • Deeply relaxed - over 95 degrees



Temperature Variables

The first and most obvious is to avoid touching the thermometer to the cold table top or laying it against a warm leg. Secondly, steroids, tranquilizers, alcohol, hypertensive medication and other drugs in the body will tend to elevate extremity temperature. Third, in the summer, hand temperatures tend to be warmer because the blood vessels are nearer the surface of the skin.

Are your hands always cold? Everyone can train to increase their hand and foot temperature and maintain a higher average temperature.

Your diet – coffee, soda pop, sugary food, lack of eating, eating a big meal before relaxing – can influence your temperature.

Stress and Temperature

The Stress Thermometer will let you see to 1/10 of one degree the stress you experience in different situations. Changes in hand/foot temperature are a reflection of blood flow – a measure of the stress response. For example, while talking about an upsetting incident involving your parents, an employer/employee, or friend, your temperature may drop 5 to 20 degrees.


In contrast, when recalling a minor misunderstanding, you temperature may only drop one degree. And yet, when you recall the warm sun on a recent vacation, your temperature may increase a full 10 degrees. What is most surprising is how quickly temperature changes occur.

The basic rule for interpreting temperature change issimple: “Warmer hands/feet indicate relaxation, while colder hands/feet reflect tension.” When the body‟sfight/flight system is activated, the muscles tense, heart rate and the vital organs speed up and as a result, blood flow is shunted from the extremities and directed to the vital organs to support the increased level of arousal. As a result, changes of 5, 10, or 15 degrees can occur within minutes.

The amount of temperature change depends on the stressor or problem and how you react to stress. You need to observe your temperature over a week in different settings to see that your temperature range is. 72 degrees may be your significant other‟s coldest temperature, while85 degrees may be your best.
