Sleeping with Your Eyes Open: What You Should Know

What Is Nocturnal Lagophthalmia?

Nocturnal lagophthalmos (NLL) is a condition where one’s body temperature rises during the night. It occurs when there are no natural light sources around us, such as candles or street lights. NLL usually happens in the evening and it causes problems for people whose bodies have not been used to low temperatures all day long. People suffering from NLL may experience fever, chills, sweats, shivers and even loss of consciousness. Some people suffer from these symptoms after only a few hours of waking up at night.

The cause of NLL is unknown but scientists believe that it could be due to several factors like lack of physical activity, stress or poor diet. Other possible reasons include hormonal imbalance and psychological issues such as anxiety or depression. There is no cure for NLL.

Treatment involves taking steps to prevent it from happening again. These steps include having a proper diet, practicing deep breaths, meditation, and avoiding stressful situations.
