1. Drinking Chili oil to keep warm in cold weather can also be said to be a way. But the prevention of colds can't be said. In a sense, the dry weather in the north is not suitable for eating spicy things like peppers. If you eat too much, you will easily get angry and catch a cold. The way to prevent colds is to strengthen outdoor physical exercise, often open windows for ventilation to keep the indoor air fresh, adhere to good living habits, get enough sleep, be in a good mood and moderately increase or decrease clothes, eat more fruits and vegetables rich in vitamins, have a light diet, and quit smoking or smoke less without drinking strong liquor. 2.

According to traditional medicine, although pepper can dispel cold, stop dysentery, kill insects, stimulate appetite and promote digestion, attention should be paid to the harmony of five flavors (sour, bitter, sweet, pungent and salty) in diet. Too much passion for pepper will easily lead to imbalance between yin and yang of viscera and produce diseases.
