4. Depression
People suffering from depression are more prone to sleep paralysis. Studies have been conducted that link mental disorders with sleep paralysis, and depression is one of those significant complications.
Epidemiologic research shows that depression is related to other sleep disorders such as insomnia, cataplexy, and hallucinations. A lot of people in this research study reported that they had experienced a sleep problem.
Though depression is not the only psychological disorder that affects sleep, it can cause oversleeping. Giving in to excessive sleep can affect the body in the same way as not having enough sleep, and both these factors contribute to sleep paralysis.
