It is common for children to sleep with their eyes open or not fully closed, especially for those with larger eyeballs or shorter eyelids. This phenomenon is also observed in children with deciduous teeth. Additionally, it should be noted that sleeping with eyes open may be a sign of poor spleen and stomach function. Here are some explanations:

Reasons for Children Sleeping with Eyes Open

1. The majority of children sleep with their eyes open due to larger eyeballs or shorter eyelids. Although they can close their eyes when awake, it is not a relaxed state. When asleep, the muscles naturally relax, resulting in their eyes remaining open.

2. This is a physiological phenomenon primarily caused by relaxed eyelid muscles. It may also be related to genetics, but it is generally harmless. In traditional Chinese medicine, the term "sleeping with eyes exposed" is used to describe this condition, which is associated with dysfunction of the spleen and stomach in children.

3. Physiologically speaking, children's internal organs are delicate, and their five viscera and six bowels are in a state of growth and development. They require a large amount of nutrients, putting significant pressure and burden on the spleen and stomach functions. Dysfunction of the spleen and stomach can easily occur due to various factors such as improper diet or illness. Treatment for children sleeping with eyes exposed may include massage and spinal manipulation. However, parents should not worry too much as this condition is often harmless and does not affect the child's growth and development.

In conclusion, most children sleep with their eyes open due to shorter eyelids. However, some children do not experience this, and it is considered a normal physiological phenomenon. Therefore, parents should not be concerned and can prevent this symptom by properly caring for and cleaning their child's face.
