Living through desert seasons causes the human body to physiologically acclimate to heat.
"I tell everyone, you live here through the seasons, you acclimate and your body changes." (said at 0:33:25)
Living through hot seasonal transitions leads to natural physiological heat acclimatization in healthy adults. Systematic review evidence demonstrates that seasonal exposure to elevated environmental heat induces measurable physiological adaptations, including reduced resting core temperature, increased sweating rate, reduced sweat sodium concentration (improved electrolyte conservation), and decreased heart rate during heat stress. The magnitude of acclimatization is influenced by environmental conditions and the duration and intensity of outdoor activity.

"Seasonal heat acclimatisation is induced across various climates in healthy adults. The magnitude of adaptation is dependent on a combination of environmental and physical activity characteristics. Providing environmental conditions are conducive to adaptation, the duration and intensity of outdoor physical activity, along with the timing of exposures, can influence seasonal heat acclimatisation."
