It is normal to have creases in the ears, which may be due to creasing during sleep, loss of collagen or normal structure. 1. Folding during sleep: If the posture is not correct during sleep, due to the softness of the auricle, it is easy to be folded, and it is a normal phenomenon that folds appear after waking up, which has nothing to do with the disease. 2. Loss of collagen: After a person gets older, because of the loss of collagen, there is sagging of the skin and other phenomena. It is also normal for people with thicker earlobes or more skin to have sagging skin and thus creases when they get older. 3. Normal structure: The shape of the ear in all people is genetically related. If there is a direct family member with creased ears, the child is more likely to show creases. The relationship between ears with creases and heart disease or other cardiovascular diseases has not been clearly proven, so it is important to seek medical attention if you experience discomfort.
