Replying to Heat - What is it?

So I randomly decided to fill my sink with hot water and watch ice melt in it. I filled it, put some ice in, and was amazed. (OOOO AHHH) I then stuck my hand in and realized that, in fact, it was hot. But then I wondered, what makes it 'hot'? Temperature is a measure of the energy of particles. 'Hot' describes high energy, meaning the particles are moving back and forth faster. But what about these particles moving makes you feel the sensation called 'Heat'. Is it that the particles collide with your hand, causing some sort of stinging feeling? Or is it that the particles collide with eachother which makes them lose some energy to heat? If it was the latter, what is this energy? What makes the energy given off by particles colliding get to your hand? Wouldn't it need more high-energy particles to transfer through 'space'? I'm stumped. If heat is some sort of 'energy' that somehow gets to your hand through some transportation, how can it be that you actually feel this 'heat'? Then I started thinking about snow, and how it melts. Does the energy of particles hit against the snow particles and transfer energy to them that way? Makes sense to me, which would show that the particles are the 'heat' and that that is what you're feeling against your skin. This then made me think about body temperature. Do you need body temperature because it is the energy in which everything happens? Like your blood flowing, nerves sending signals to your brain, and such. If you lost temperature would everything stop functioning properly because you lost 'energy' and thus the blood flows slower since the particles do not collide, the sensations from nerves don't get to the brain as fast because they are lower energy? Makes you think....Now back to my baked potatoes.
