What part of the body has 500000 sweat glands?

The human skin has approximately 500,000 sweat glands, primarily concentrated in areas such as the palms of the hands, soles of the feet, and the forehead. These glands play a crucial role in thermoregulation by producing sweat, which cools the body as it evaporates. The distribution and density of sweat glands can vary between individuals and different regions of the body.
