Why is your mouth thirsty? Why is your mouth dry?

1, the weather is dry. I believe many people have a deep understanding that in dry weather, lips are particularly dry. This is because 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 they need hydration.

2. The body lacks vitamins. If the corners of the mouth begin to crack, the reason may be a lack of vitamins, because people's lips are called "red lips", and wetness is maintained by sebaceous glands. Vitamin supplementation helps to increase sebaceous glands and keep lips moist.

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

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