The pungent substance in pepper is capsaicin, which is collectively called capsaicin. When cutting peppers, capsaicin sticks to the skin, which will dilate the capillaries, lead to redness and fever of the skin, and accelerate the local metabolic rate. At the same time, it will also stimulate the pain nerve, which is why we usually feel burning our hands. It is generally believed that this is caused by the chemical transformation of nerve endings of skin by capsaicin.

Second: an effective way to get rid of spicy feeling.

1, you can apply alcohol to dissolve capsaicin on your hands.

After cutting pepper, you can wipe your hands with an alcohol cotton ball in one direction, then wash your hands with clear water, dry them again, and rub them three times until the symptoms are relieved.

2, you can also wash your hands with a small amount of vinegar.

Vinegar is acidic and can be neutralized with capsaicin.

3. Washing hands with hot water is also good.

Capsaicin will produce irritating evaporation at high temperature, although it is not as good as alcohol and vinegar, but the effect is better than cold water.

4. Soaking your hands in iced milk also has analgesic effect.

5, rubbing with orange peel on your hand can also relieve pain.

6. Apply toothpaste to your hands, and wait for 10 minutes before washing it with clean water. Toothpaste is alkaline and pepper can be neutralized by acid and alkali.
