Sleep routines should be viewed as a 24-hour process: sleeping well means having a better day, and vice versa, having a better day leads to better sleep. When children with ASD experience poor sleep quality, key symptoms such as aggression, mood swings, sensory hyperresponsiveness, impaired performance and memory, compulsive behavior and rituals, stereotypies, and especially socialization and communication, increase.

It is also important to understand the impact that the lack of sleep in these children has on their families and caregivers, since they too will sleep poorly and, therefore, it will affect their rest and functionality during the day.
