Why is 98 degrees too hot?

How come that even though ur body temperature is 98.6 degrees, if it is 98 degrees outside, then we are uncomfortable. You would think that would be the perfect temperature

Someone else with more expertise will probably be along shortly to go more in depth but to put it simply, we need a lower temperature outside our body to vent our extra heat, otherwise we’ll get too hot.
