A lot of people are mentioning fluids and air-fuel ratios, but I think the other issue is also the metal that makes up a lot of the engine parts that need to warm up.

Taking cold metal and applying a sudden increase in temperature and pressure to it could potentially lead to catastrophic (and premature) failure of those parts.
