Try not to eat spicy or irritating food in winter, because the weather is very cold and dry. If we eat these foods often, it will definitely cause excessive internal heat. Be sure to eat more protein or foods with more vitamins, which can effectively prevent the occurrence of oral ulcers.

Try not to drink too hot drinks in winter, because there are some heated drinks with a lot of sugar, which will increase the risk of diabetes. If you feel that the drink is particularly cold, you can scald it with hot water.
