Whichever type of alcohol you consume, they all cause burns, not
literally but they give a burning sensation. In extreme cases like dry
shots, you might feel like your mouth and the entire throat are being
scalded. The reason why alcohol burns you when you drink it is because
it messes with the heat receptors found in the mouth, which normally
react to heat from boiling water and/or fire.
These cells, known
as VR1 receptors, usually react when exposed to heat by shooting up
signals that there is something to the brain. You eventually feel the
nerve as a burning sensation and sometimes pain. This is basically the
same sensation that you experience after consuming some spicy sauce.
So
now, what is the actual reason why alcohol burns you when you drink it?
Let us try to answer this. Alcohol lowers the threshold of temperature
that the receptors need to send the signal, which is normally 42 degrees
to 32 degrees.Normal body temperature is around 37 degrees. This leaves
you feeling like the alcohol is actually burning you. Even if the
alcohol is chilled, it will still cause a sting on cuts. This explains
why water causes no stings on a cut since there is no reaction involved.
Alcohol
drains water from the skin cells causing them to dry out and they
indicate the stress as a burning sensation. Once you take alcohol, it
makes you feel warm because when consumed, it acts as a drug and causes
the blood vessels to expand. This causes more blood to flow to the skin,
feet and hands and leave you with a warm sensation. The inflammation of
the cells generates heat, which is the source of the burning and
stinging sensation and the fact that the threshold of the receptors has
been lowered too much leads to pain.
However, this feeling of
warmth does not mean you really are warm! Blood act as a medium for
transferring heat, and if it is at the body surface, then this means
that you are losing heat. It is therefore very risky for someone
suffering from hypothermia to take alcohol. However, if you are just
cold and in a warm place, taking shots of spirit to keep you warm and
make you comfortable does not do you harm.
Exposing these
receptors to alcohol is basically the same as applying an antiseptic on a
cut. There are people who believe that alcohol-based disinfectants are
the best for applying to a cut. This could never be more wrong! What
these chemicals actually do is that they kill all cells, including the
good healthy ones. Don't you think that this is the reason why you feel
that burning pain? Therefore, as much as they clear off the bad
bacteria, they also slow down the whole process of healing. If you want
the best and sure most healing process, do yourself a favor and leave
antiseptics out of the question. Just run some clean, cold water over
the wound. By so doing, you get to clean the wound without killing any
healthy cells.
