Giving your body time to adjust over a few days or a week can promote physiological adaptations to heat, such as increased perspiration efficiency, increased blood flow to the skin, and the ability to move around with a lower heart rate and core body temperature. increase. “Your body is a wonderful machine,” said Gandhi. “The longer it takes to adapt, the better.”
