Several major reasons why girls can't close their eyes tightly when sleeping

Anyone who has been a mother will find that infants, especially younger ones, may keep their eyes open when they sleep, but the degree of this varies. Some children sleep with their eyes narrowed, while others appear to have their eyes open. In this regard, doctors pointed out that this is a physiological phenomenon and may be genetic, but in severe cases it may also be caused by disease. This article briefly explains the reasons why girls cannot close their eyes tightly when sleeping.

1. Muscle relaxation

During sleep, the nerves' weak control over muscles, low tension of the orbicularis oculi muscle, or insufficient relaxation of the levator palpebrae superioris muscle may lead to incomplete eye closure.

2. Disease

Some diseases can also cause incomplete eye closure, such as acute facial neuritis. Some people cannot close their eyes because of certain diseases that cause their eyeballs to protrude, such as scleral staphyloma, orbital tumors, hyperthyroidism, etc.

3. Sheep Eye

Some people have congenital malformations of the orbicularis oculi muscle, or their upper eyelids are too short, which causes the palpebral fissure to not close completely, leaving a gap when they sleep, as if their eyes are half-open, commonly known as "sheep's eyes".

4 Nerve palsy

Some people suffer from facial nerve paralysis, and certain brain diseases cause the facial nerve to lose control. The eyelid muscles lose tension, causing the palpebral fissure to enlarge and making it difficult to close the eyes.

5. Inflammation

Some people have eyelid scar shortening and skin defects due to inflammation, ulcers, trauma, etc., which cause eyelid closure problems and prevent them from closing their eyes completely all day long. Although these people "can't sleep with their eyes closed", because part of their eyelids are closed, the black pupils are always tilted to the closed side, leaving only the white part of the eyes exposed. Therefore, the eyes are no longer stimulated by light and this does not seriously affect sleep. At the same time, Chinese medicine calls the inability to close the eyes when sleeping "unclosed eyes", which was recorded as early as in the medical work "Lingshu Xieke" more than 2,000 years ago. It is believed that it is caused by the lack of interaction between yin and yang.

6. Spleen deficiency

People with weak spleen will keep their eyes open when they sleep. Usually half open. But some people are born to sleep with their eyes half open. For such people, the darker the environment is when they sleep, the better, so as to minimize damage to their eyes. Such people usually have poor eyesight.
