Pain caused by chili pepper is roughly a grade 2-3 pain according to the pain numerical grading method, and grade 10 is the most severe pain. However, due to the different pain sensitivity and tolerance of each person, there is a large individual difference in the specific feeling, so it is not possible to generalize. Moreover, there are different criteria for grading pain, and it is impossible to determine a uniform grade. Chili peppers contain capsaicin, which stimulates the peripheral nerves of the fingers and causes a constant pain and burning sensation. For those who are sensitive to pain, they may think that the pain caused by chili pepper is heavier, and the pain is closely related to the contact time, the type of chili pepper, and whether the skin of the hand is broken. After the chili pepper spicy hand should promptly rinse the hand with water to wash the residual chili alkali on the surface to reduce absorption. Because the capsaicin can be dissolved in alcohol, the right amount of alcohol applied to the joint rinse repeatedly several times, the pain can be relieved. In addition, if the hands are in severe pain, swollen and swollen, as well as red spots, it is recommended to consult a dermatologist promptly to prevent serious allergic reactions that may endanger health. It is recommended to use your finger belly to press the pepper when cutting the pepper and avoid pinching the pepper with your nails, which can effectively avoid the situation of hot pepper hands.
