When we eat or drink a hot thing or spicy thing, the heat flows from it to our body and we feel its sensation. Our body is made up cells and cells are made up of molecules. At normal body temperature these molecules are in motion but when hot substance enters our body their motion gets accelerated causing vibrations which results in cell breaking and this breaking of cells gives us the hot burning sensation.

Ram about what you are talking I cannot understand it. Tell me briefly.

Mirchi has red chilly flakes which irritates the normal lining of oral cavity which burns due to excess irritation. This leads to heat in the tissue and thats why we feel more hotter when we eat mirchi..

That means mirchy leads to hot.
But I think separate taste buds are there for mirchi and hotness :unsure:

My doubt not cleared yet :S

As i mentioned before there are different taste buds and receptors on our tongue. When we eat spicy or sweet foods the taste buds are immediately activated and thus we get taste to the food. Hence if u eat mirchi the receptors on the tongue immediately capture that heat through taste buds and we get hot and spicy taste from mirchi. But due to excess spiciness the lining of our oral cavity get damage. So this time if u eat spicy again the irritated mucosa will burn, taste buds will get activated and u will feel more spicy and hotness.

That's great information Sheetal.If i correlate it,it means chilly and hot things are alike for the taste buds of our tongue. :)

I need a help will you give a appointment with that Doctor.It is Urgent.............. :P :P :P :P :P :P :P
