What is the Origin of Core Temperature Elevation?

The therapeutic use of heat dates back to ancient cultures, but the scientific understanding of core temperature elevation originates from modern thermophysiology and the study of hyperthermia. Clinical application in wellness is based on the recognition that transient, controlled thermal stress activates protective molecular pathways. This strategy leverages the body's innate defense mechanisms for systemic benefit.

What is the Mechanism of Core Temperature Elevation?

Raising the core temperature stimulates the expression of heat shock factors (HSFs), which then transcribe heat shock proteins (HSPs) to protect existing proteins from denaturation. This elevation also acutely increases heart rate and cutaneous blood flow, mimicking cardiovascular exercise. Hormonally, it can lead to transient increases in growth hormone and prolactin, supporting tissue repair and recovery.

Core Temperature Elevation

Meaning

Core Temperature Elevation is the intentional, controlled increase of the body’s internal, deep-tissue temperature above its normal homeostatic range, often achieved through environmental means like sauna use or intense exercise. This physiological change acts as a systemic hormetic stressor, triggering a cascade of adaptive cellular and hormonal responses beneficial for health and longevity. It is a potent stimulus for heat shock protein synthesis and improved thermoregulatory function.
