If the eternal temperature of the lens is the problem, the lens hood will have little or no effect. Heat will dissipate much faster through the metal lens barrel than it will through the glass element at the front.
Erm, I dunno. Did you watch the video by Steve Perry? It's not the faster rate that the heat may be leaving the lens body, it's the fact that heat haze is occurring in the hood. In Alberta last week, I had the hood off at all times when shooting.
