Some people find that falling asleep is a difficult and unsettling experience, despite the fact that sleep is supposed to be a pleasant trip through the night. Non-Rapid Eye Movement (NREM) Sleep Arousal Disorders are a collection of sleep disorders that are defined by periods of incomplete awakening from NREM sleep. This can lead to strange behaviors and bewilderment in the affected individual. In this blog, we will discuss these disorders in easy-to-understand language, disclosing their causes, symptoms, effects, and solutions.

What are Non-REM Sleep Disorders?

NREM Sleep Arousal Disorders, commonly referred to as parasomnias, are characterized by the occurrence of unexpected actions or activities while the individual is in the NREM stage of sleep. These problems manifest themselves during the deeper periods of NREM sleep, in contrast to nightmares and night terrors, which take place during the REM (rapid eye movement) stage of sleep.

Types of Non-Rapid Eye Movement Sleep

Sleepwalking (Somnambulism):  Sleepwalking, also known as somnambulism, is a condition in which a person unconsciously engages in a variety of activities while sleeping. These actions can include walking, talking, or even eating. They frequently have no recollection of the events in question.

Sleep Terrors (Night Terrors): Sleep terrors, also known as nightterrors, are characterized by extreme episodes of anxiety or restlessness that occur during NREM sleep. Yelling, thrashing, and a lack of reaction to attempts to comfort the individual are all examples of behaviors that may fall into this category. People frequently report that they have no memory of the events that occurred.

Sleep-Related Eating Disorder (SRED):  Sleep-Related Eating Disorder (SRED) is a condition in which individuals eat during periods of sleep, despite frequently being unable to recall doing so. This may contribute to poor eating habits, which in turn can lead to weight gain.
