Everyone is familiar with the feeling when you chew a mint cheese and feel cool in the mouth. An even greater effect can be achieved, having walked in the mouth of mint leaves and drinking water after that: a feeling appears as if hecy was in the mouth. But why does cold effect occur if the language remains room temperature?
It's all about the substance called "Menthol". As is well known for the perception of various feelings (heat, cold, touch, etc.) corresponds to millions of receptors located on the skin and mucous membranes. Among them there are cold receptors, whose task is to prevent the brain on the temperature drop. When it becomes cold, the receptors immediately give the signal to our brain. He, in turn, narrows the vessels for which less blood begins to the freezing place. It is on these receptors that Menthol affects, making them more sensitive than others. Cheated receptors think that the temperature dropped, and signals the brain about this, and we, in turn, we feel cool.
The greatest amount of menthol is contained in the peppermint. Of course, it is known to marketers who are writing "with taste of mint" on their gums, sucking candies or toothpaste. But if Menthol for production was really obtained from mint, thousands of hectares would be planted with this plant. Now almost all menthols are made artificially. But trying real mint is still very simple: it can be raised without any problems in the country, especially she is unpretentious in care and can grow in a cool climate.
This is interesting: similar, but the pepper chili pepper is possessed by the effect: it makes the receptors reacting to hot, actively transmit nerve impulses into the brain. And what will happen if they first eat chili pepper, and then chew mint? If you tried to do so, then share your feelings with us!
