What's with the dry mouth? Why is the mouth dry?

1. The weather is dry. I believe many people have a deep understanding that in dry weather, the lips are particularly dry. This is because the lips are mucous membranes without sweat glands and are in direct contact with the external environment. If the external environment is too dry, water will soon be lost. As a result, the lips are getting drier and drier and need to be replenished with water.

2. The body lacks vitamins. If the corners of the mouth start to crack, the reason may be the lack of vitamins, because the human lips are called "lip red edge", and the wetness is maintained by sebaceous glands, and vitamin supplementation is helpful to increase sebaceous glands and keep lips moist.

3, cheilitis. If you always feel chapped lips, you may have chronic cheilitis. Lipitis is often a high incidence among young people, which is mostly caused by bad daily habits, such as lip injury and dry lips licking.

4. Physical factors. Allergic to cosmetics or suffering from certain diseases may also lead to dry lips. In addition, people suffer from diabetes, mood swings, and often eat food that gets angry, which is also easy to cause dry lips.
