<span>The answer is ‘radiating excess body heat into the
environment’. Vasodilation of cutaneous

of heat to the environment. This is also ideal if there is a breeze in the environment
to facilitate this process (the reason why people us fans in hot days). If the
body is unable to shed this heat (maybe because it is too hot in the environment)
then the person may experience heat stroke</span>
