Heat Acclimation

Meaning

Heat Acclimation is a physiological adaptation process achieved through repeated, controlled exposure to environmental heat stress, leading to beneficial adjustments in thermoregulatory and cardiovascular function. This process enhances the body’s ability to tolerate high temperatures, reducing core body temperature and heart rate response during exertion. In the context of hormonal health, heat acclimation can modulate the endocrine system by increasing plasma volume, improving insulin sensitivity, and upregulating the expression of heat shock proteins. These systemic changes contribute to overall metabolic health and stress resilience.
