Quick Summary

Sleep disorders encompass a range of conditions that disrupt normal sleep patterns. These include insomnia, characterized by difficulty initiating or maintaining sleep, and sleep-related breathing disorders like sleep apnea, where breathing is repeatedly interrupted. Other categories include hypersomnia (excessive daytime sleepiness), circadian rhythm disorders (e.g., jet lag), parasomnias (such as sleepwalking), and movement disorders like restless legs syndrome. While many disorders affect both children and adults, some are specific to childhood. Chronic insomnia, for instance, may be linked to psychological issues, and treatments often focus on cognitive and behavioral programs rather than solely medication. Sleep is crucial for physical and mental health, aiding in memory consolidation, physical repair, immune function, and emotional regulation.123456
