I would, but that's me...
And think about it a second. For Improved Invisibility to work with visual spectrum light, it's going to be keeping it from coming in, notionally like you seem to think, because it's the reflection of that light that we interpret as sight. Thermographic vision, on the other hand, relies on EMITTED energy, not REFLECTED, so the sight shield would have to TRAP it, right? In which case, since the (meta)human body is highly exothermic, you wouldn't freeze to death, you'd braize in your own juices!
*grin*
Given that Magic can create sustenance from pure mana, it wouldn't be a stretch to assume it works in reverse... turn that exothermic radiation into mana which dissipates in the environment.

Keep in mind that a lot of the Manipulation spells seem to break the (currently understood) laws of inertia, gravity, thermodynamics and countless others. That's why they call it "magic". The general description of Improved Invibility talks about light bending, but that's a scientific description; I expect what the spell is really doing is just keeping light from reflecting, not keeping it from getting to you. Thermal's a little harder, but compared to, say Levitate? Or Dragons (that can fly), or telepathy or ... for that matter, how is science going to explain ANY Mana spell? There's nothing there to quantifiably measurable, so how do you fit it anywhere into a physics equation in the first place?
The only physical law Magic can't break apparently is anything related to space/time. No teleportation, extradimensional pockets or time travel.
Honestly, I wouldn't be surprised to find that Magic *does* break Space/Time but that we simply haven't figured out *how* to get it to do so as of yet.
Prime example: The spirit power of Movement. That has to break space/time. The object under the effect of Movement doesn't move faster yet covers more space. Space/time was bent to make that happen. It's very much like Warp Drive from Star Trek. The relative speed of the vessel doesn't change. It simply went to a dimension where the distances between points A & B were smaller.
Ex: I can travel at 100 meters / sec.
In Dimension 1, I need to travel from Point A to Point B. The distance between them is 1,000 meters. At my movement speed, that would take 10 seconds.
But if I go to Dimension 2, the distance between those two points is only 500 meters. So I transit from D1PA to D2PA and then travel from D2PA to D2PB and then transit back to Dimension 1 which has me arriving at Point B... in 5 seconds instead of 10 seconds.
So perhaps further research needs to be done to determine how exactly spirits are able to bend space/time to accomplish the feat of faster travel without extra speed or altering the flow of time.
**Edit: BTW, scientists have apparently managed to get mice to levitate in an anti-gravity field. Saw an article on it on Live Science yesterday. So Levitation isn't so far out there...
