Sleepwalking, also known as somnambulism, typically occurs during deep sleep stages. During these stages, the brain is in a state of reduced consciousness.
Consciousness and Sleep: According to the study on consciousness, the brain's awareness is lower during deep sleep, which can lead to sleepwalking as the brain does not fully wake up.
Sleep Disorders in Children: In pediatric sleep studies, it is noted that sleep disorders like sleepwalking are more common during deep sleep because the brain is not as active in controlling movement and behavior.
Role of GABA: GABA, a neurotransmitter, plays a role in sleep. It helps keep the brain calm and less active, which is why sleepwalking can happen when GABA is working to keep the brain in deep sleep.
By understanding these aspects, we can see why deep sleep is a common time for sleepwalking to occur.
