What Are the Symptoms of Insomnia?
Insomnia is a sleep disorder that includes one or more of the following symptoms:
- Having difficulty falling or staying asleep
- Waking up frequently during the night
- Waking up too early in the morning
- Waking up feeling unrefreshed
Insomnia often leads to sleep deprivation, which causes you not only to be tired but also to feel irritable and lethargic and have difficulty focusing on tasks.
People with insomnia may also become anxious about sleeping. They worry about not getting enough rest; for some, just getting ready for bed makes them tense and uneasy. And, not surprisingly, these feelings make falling asleep enormously difficult.
