During pregnancy, a woman's body undergoes several physiological changes to support both her own health and the developing fetus. One of these changes is an improvement in the body's ability to dissipate heat. This occurs due to increased blood volume and enhanced vascularity, particularly in peripheral areas, which facilitates greater skin blood flow.

Moreover, hormonal changes, particularly increased levels of estrogen and progesterone, also play a role in enhancing a woman's sweating response and thermoregulation. These adaptations allow the pregnant body to maintain a stable internal temperature, which is crucial for the health of both the mother and the fetus.

The physiological need for efficient heat dissipation becomes more pronounced as metabolic activity increases during pregnancy, leading to greater heat production. The body's capacity to manage heat effectively is essential, especially during physical activity or hot environmental conditions, making the improvement in heat dissipation a vital adaptation during this period.
