[Star Wars] Shouldn't getting hit by a lightsaber or blaster bolt cause the human body to explode instead of cauterize as shown in the movies?

I often hear it tossed around that the lightsaber cauterizes the wound when it passes through. However if the blade is hot enough to fuse blood vessels shouldn't it also boil your liquids and cause them to expand as gasses? This should lead to messy explosions of blood and guts instead of neat cauterized wounds. And this is shown in the universe as well when Hans explodes the wall with his gun and the clone troopers shoot down columns and rocks. However when they hit a person they just turn into neat holes.

**ENERGY DENSITY.**  


Being hit with a lightsaber imparts a lot of heat on the cut surface, but does not transfer enough energy to boil tissues more than 1-2 cm from the cut.  


Notice that in the majority of lighstaber fights, the stabs and slashes are extremely fast. The actual time of contact between flesh and the lighsaber is *fraction of a second.*  


However, recordings show a few instances of people being **impaled** with a lightsaber, and then the **blade being left in their body for a second or two**. This is infamously how Master Qui Gon died, or how Han Solo met his end. In such situations, the heat of the saber has enough time to penetrate the body and boil the organs, and cause steam to run through the victim, causing internal burns and hemmorhages. In such an instance, the person cannot be saved and dies in seconds.
