The body dissipates heat 4 ways:
Your body's “temperature regulation center,” called the hypothalamus, adjusts during this period. Changes during this period include sweat rate increases, sweating begins earlier, better distribution of sweat over the whole body, sweat becomes hypotonic (less salty), and blood volume increases.
*Sweating during exercise is very important and a great benefit to body temperature regulation, provided the sweat can evaporate easily. Be careful during hot and humid conditions because there is so much moisture in the air that it’s hard for your sweat to evaporate and your body temperature can raise quickly. The average person has between 2-4 million sweat glands throughout the surface of our bodies.
