Insomnia occurs when an individual has persistent difficulty falling asleep and/or staying asleep.
Individuals with chronic insomnia experience problems falling asleep, staying asleep, or feeling fatigued throughout the day. This can often be associated with significant distress and impairment in functioning.
Individuals with insomnia may spend a lot of time worrying about sleep (both during the daytime and nighttime). They may become preoccupied with monitoring their bodies (“Am I tired yet?) or their environment (“What time is it?”) leading to increased arousal. This increase in arousal can be associated with more difficulty sleeping.
