Hard to say, depends on how the experiments were going. For example, if you stand on snow and melt it you're going to lose body temperature quickly, so it seems better not to melt the snow. However, if you melt the snow quickly enough and form a puddle the water will distribute heat equally resulting in no perception of cold. Also, below freezing it's a lot more comfortable and warm on top of snow than bare concrete.
There's two key things here. Humans perceive hot & cold through differences in temperature and the human body, when on automatic pilot, usually defaults to worst-case-scenario.
On perception of cold, the body panics and changes blood flow to keep heat in the core. This automatically makes you more easily damaged by the cold because now you have insufficient heat in your extremities and it 'feels' colder. It's a vicious cycle.
That's on auto-pilot. If you don't let your body go in to panic mode, made easier by reducing temp differences between body parts, you'll find that the human body functions quite well in the cold. Learning to increase/decrease heat distribution in your body is key here along with being able to shut the machine up. It's one of the easiest body systems to access. Just requires a little simple visualization a la "my hand is getting hot/cold".
