Why? Take a look at the scientific principle:
The hot pepper in the material to produce spicy flavor is a collectively known as capsaicin capsaicin. When cutting chili peppers, capsaicin gets on the skin and causes microvascular dilation, leading to redness and heat in the skin and accelerating the local metabolic rate. At the same time, it also stimulates the pain nerve, which is why we usually feel burning hands. It is generally believed that this is caused by the chemical transformation of the nerve endings of the skin by capsaicin.
Capsaicin is soluble in ethanol and alkaline aqueous solutions, but not in cold water. In industry, the extraction of capsaicinoids from chili peppers is done by using edible alcohol as an extracting agent. Therefore, according to this principle, in life, you can take the method of applying alcohol to dissolve the capsaicin on your hands. After cutting chili peppers, available alcohol cotton ball one-way hand rub, and then wash your hands with water, and then dry, and even rub three times until the symptoms can be relieved.
See? In fact, hand soaked in cold water inside, or with ice can only be temporarily anesthetized, once stopped, the hand will still be very hot.
Additionally, some folk remedies, did not personally try, sent out to give you a reference reference:
1 roasted on the fire for a while (this is a little cruel, anesthesia sensory nerves? If cooked how to do ah?)
2 soaked in soapy water
3 apply a little toothpaste
4 put the mouth force sucking (it looks like the chili pepper to transfer to the mouth, is not it more difficult? Might as well go out on the street and get a handshake)
Actually, it's best to put on rubber gloves to cut chili peppers so they don't get hot on your hands. By the way, if you accidentally get hot hands, don't rub your eyes, scratch your butt, and any other sensitive parts of your body such as your ***, or else, uh, the consequences will be severe.
