Heat Transference 3
• Body heat is transferred by
conduction, convection,
radiation, and evaporation.
• During exercise, evaporation
is the main means of heat
loss; during rest, radiation is.
• Humans maintain a constant
internal temperature of 36.1

to 37.8 °C (97.0 to 100.0 °F).
37. (97. 100.
• Higher humidity reduces
potential evaporation and
thus affects heat loss.

Basic, (E. Green), Temperature Training
1. Discuss the rationale and answer questions to patient.
2. Explain biofeedback machine.
3. Apply the thermistor.
Peripheral Temperature Biofeedback:
Basic Methodology
4. At least 15 min of relaxation followed by warming visualization
(for instance heaviness and warmth autogenic exercises).
5. Visualize desired changes with closed eyes.
6. Expose patient to temperature feedback (sometimes with
autogenic affirmations.

Temperature Biofeedback Session Sources of artifact
• Outside temperature (baseline status)
• Room temperature (sets lower limit)
• Breeze (removes heat and evaporates
sweat)
• Probe contact and “blanketing effect”
