The condition of "thick feeling" heat in a small place that you have to enter; also an exclamation of the same when experiencing it.
When it's very hot outside and your car has been shut up all day, and you open it for the first time to get in and the temperature takes your breath away - that first blast of heat escaping is "heatness".
