Its that an observation is always an energetic interaction. You can't measure a system without interacting with it and at the particle scale every interaction has enough energy to affect the particle in some way. Like when you light up a room you're slightly heating the molecules in it.

If your room is small enough that the light bulb is bigger than the room, this effect becomes very noticable.
