Good point. The more work you do, the more energy you dissipate as heat.
Since your body will try to maintain it's temperature at 98.6 degrees, as
soon as you generate heat faster than your skin can dissapate it, you will
begin to sweat. Usually, when you shovel snow, you are bundled up with
winter clothes and believe it or not, the temperature of the air under the
clothes has risen to above 98.6 degrees when you start to sweat... removing
your winter coat will allow the heat to escape and the sweating will stop.
