What should I do if my hands feel hot after cutting peppers for a few hours?
You can use alcohol, vinegar, hot water to wash your hands and other methods to remove the spicy taste.

1, wash your hands with a small amount of vinegar, because vinegar is acidic and can be neutralized with capsaicin. If there is no medical alcohol or vinegar, it is good to wash your hands with hot water, because capsaicin will produce irritating evaporation at high temperature. Although it is not as good as alcohol and vinegar, the effect is better than cold water.

2. 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.

3, pepper can be relieved by salt rubbing, because salt is a neutral substance, and its acidity and alkalinity can take effect on capsaicin. The specific operation method is to grab a small handful of salt for cooking at home, put it in the palm of your hand, and rub your hands with each other. Remember to rub more places where it is difficult. After rubbing, dilute it with a little water and then rub it with clear water.

Extended data:

1 The pungent substance in pepper is 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.

2. Before cutting the pepper, apply cooking oil on the hand holding the pepper before cutting it, so that even if the pepper sticks to the hand, wash the oil on the hand with soap after cutting, and it will not touch the skin.
