Thermal Resilience

Meaning

Thermal resilience is the physiological capacity of an individual to rapidly and effectively adapt to and recover from exposure to environmental temperature extremes, maintaining core body temperature and stable internal homeostasis without excessive strain on the metabolic or cardiovascular systems. This metric reflects the robust function of the autonomic nervous system and the efficiency of metabolic processes, including the hormonal regulation of thermogenesis. High thermal resilience is a key indicator of overall physiological fitness and a reduced allostatic load, correlating with better long-term health and vitality. Enhancing this resilience is a goal of many longevity and wellness protocols.
