Insomnia is a sleep disorder characterized by the persistent difficulty of falling asleep, staying asleep, or experiencing non-restorative sleep, even when there is ample opportunity for adequate rest. This condition can either be chronic, lasting for an extended period, or occur episodically, with periods of better sleep alternating with periods of insomnia. Insomnia can significantly impact a person's well-being, affecting their daytime functioning and overall quality of life. There are different types of insomnia, and the symptoms, causes, and side effects can vary.

Onset Insomnia: Onset insomnia refers to difficulty falling asleep at the beginning of the night.
