What is the cause of chapped lips in children?

Children cannot take care of themselves because they are young. Especially children with anorexia are prone to chapped lips due to malnutrition or vitamin deficiency. This makes the children particularly painful and affects their normal diet, which makes parents even more anxious. Many parents will ask their children what is wrong with their chapped lips after their children have such a situation. Let us understand this situation.

The red area around the human lips is called the "vermilion border". Its moisture is maintained by the local abundant capillaries and a small number of underdeveloped sebaceous glands. Due to the low humidity and strong winds in autumn, the blood circulation of human skin and mucous membranes is poor. If you eat less fresh vegetables, the body's intake of vitamin B2 and vitamin A will be insufficient, and the skin and mucous membranes will become dry and cracked.

Some people like to lick their lips with their tongue to moisten them. In fact, this is a bad habit, because licking the lips can only bring temporary moisture. When the moisture on the lips evaporates, it will take away more moisture from inside the lips, causing your lips to fall into a vicious cycle of "dry - lick - drier - lick again". As a result, the more you lick, the more painful it becomes, and the more cracked your lips become. What's more, saliva contains substances such as amylase. When the wind blows, the water evaporates, taking away the heat and making the temperature of the lips lower. The amylase then sticks to the lips, causing the deep connective tissue to contract and the lip mucosa to wrinkle, making the lips drier. In severe cases, it may cause infection, swelling and pain.

Through the above, we know the reasons why children have chapped lips. Once a child has chapped lips, parents do not need to panic. First of all, do not let the child have the bad habit of licking his lips. Then we need to adjust the child's diet, let the child drink more water, and eat more fresh vegetables and fruits rich in vitamins. After a period of time, this situation will improve.
